Sigma Releases 24mm f/2 and 90mm f/2.8 Lenses for E-Mount and L-Mount Cameras

Sigma releases 24mm and 90mm lenses

Sigma has unveiled two powerful lenses for Sony E-mount and L-mount cameras: the 24mm f/2 DG DN Contemporary and the 90mm f/2.8 DG DN Contemporary.

The lenses slot into Sigma’s “I” lineup, a series of glass featuring top-notch build quality, portable bodies (Sigma claims the I series is perfect for “everyday use”), and high-resolution imaging on par with even the most demanding mirrorless cameras. 

And the Sigma 24mm f/2 continues this I series tradition, offering outstanding build quality in a portable package. The lens is entirely metal, from the barrel and mount to the focus and aperture rings (and yes, the 24mm f/2 does sport a manual aperture ring, for photographers who prefer a more tactile, analogue method of shooting). 

Sigma 24mm f/2 lens

Sigma notes that the 24mm f/2 works well for “night sky photography, events, and interiors,” as well as “day-to-day use.” It certainly should perform well in low-light situations like indoor events (e.g., weddings) thanks to the wide f/2 maximum aperture, though Sigma might be selling the lens short; in addition to the aforementioned uses, I’d also peg the 24mm f/2 as an excellent street photography lens – it’s compact, fast, and sharp, even if its 24mm focal length is wider than the 35mm/50mm street photography standards – a capable landscape lens, especially for photographers looking to lighten their load, and an ideal travel lens.

The 24mm f/2 aims for optical perfection. Sigma explains that “lens resolution is extremely high and is uniform from the center to the periphery of the image,” while the lens features “the highest level of optical performance even at its maximum aperture of f/2.”

And the price is a quite reasonable $ 639 USD, ideal for budget-conscious photographers in need of a second or third lens.

The 90mm f/2.8 features a similar design – all metal, to match existing I-series lenses, plus a manual aperture ring, a compact build, and a “sleek, stylish finish.” At 90mm, I hadn’t expected the lens to be quite as travel-ready as its 24mm counterpart, yet the 2.4 inch (59.7 millimeter) barrel is ultra-slim and even pocketable.

Sigma 90mm f/2.8 lens

Who should buy the 90mm f/2.8? Sigma advertises the lens as ideal “for portraits, close-ups, weddings, and events,” and I’d probably add product and still life photography to that list, thanks to the short telephoto focal length, not to mention the “exceptional resolving power that can keep up with the latest ultra-high-resolution cameras.” Plus, the lens offers a 1:5 magnification ratio; it’s no true macro lens, but can certainly get you a close perspective for detail shots.

Like the 24mm f/2, the 90mm f/2.8 sells for a very reasonable $ 639 USD. And both lenses should begin shipping at the end of September, so if you’re a Sony or L-mount shooter looking for a well-built, compact prime, I highly recommend you take a look.

Now over to you:

What do you think of these new lenses from Sigma? Do either of them appeal to you? Share your thoughts in the comments below!

Sigma Announces the “Reborn” 35mm f/1.4 Art for E-Mount and L-Mount

30 Apr

The post Sigma Announces the “Reborn” 35mm f/1.4 Art for E-Mount and L-Mount appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

Sigma announces the "reborn" 35mm f/1.4 for E-mount and L-mount

Earlier this week, Sigma announced its latest lens, the 35mm f/1.4 DG DN Art for L-mount and Sony E-mount cameras. 

It’s a redesign of Sigma’s popular 35mm f/1.4 DG HSM Art lens, but “reborn for mirrorless and empowered through Sigma’s [latest] technology.” Specifically, you can expect superior optical performance compared to the original 35mm f/1.4, especially in terms of bokeh quality and aberration reduction; Sigma also promises “fast and quiet AF,” plus “a professional feature-set” packed into “a compact body.”

I’m a fan of the Sigma Art line, but I’ve been frequently frustrated by the size and heft of the lenses. Fortunately, the 35mm f/1.4 addresses these problems. Sigma rates it as “significantly smaller and lighter than the existing 35mm f/1.4,” and while I wouldn’t go that far (it’s about 0.6 in/15 mm shorter and 0.7 oz/20 g lighter), the lens should balance better on Sony mirrorless cameras – especially Sony APS-C models – than its predecessor. 

Above, I mentioned the improved optical performance on the new 35mm f/1.4. Sigma’s anti-flare and anti-ghosting technology, as well as low dispersion elements designed to combat aberrations, guarantees superb clarity even in tricky shooting conditions. And you can expect improvement to the (already impressive) bokeh, thanks to the 11 aperture blades, compared to 9 on the previous version.

Sigma 35mm f/1.4 lens announcement

Interestingly, Sigma has added an aperture ring to the redesigned 35mm. You have the option to adjust the aperture via the camera dials, but for those who prefer a more tactile shooting experience, manual aperture selection is always an option. The lens is also dustproof and splashproof, so the 35mm f/1.4 can be used successfully for outdoor event photography, street photography, and even landscape work. And while I haven’t had the opportunity to hold the 35mm f/1.4 in my hands, I’m confident that it, like all of Sigma’s Art lenses, can take a significant beating.

The Sigma 35mm f/1.4 DG DN Art should appeal to plenty of photographers, especially portrait shooters in need of stunning background bokeh in a portable (and inexpensive) package, street photographers after a wider focal length, and event photographers looking for stunning optics and a fast maximum aperture. But I can also see the 35mm f/1.4 working as a travel lens, an architectural lens, and even a landscape lens.

The brand-new Sigma 35mm f/1.4 DG DN Art is currently available for preorder, and you can grab it for just $ 899 USD. Expect the lens to start shipping in May.

Now over to you:

Are you impressed by the Sigma 35mm f/1.4? What do you think of it? Have you used the older version, and how do you think the new version will measure up? Share your thoughts in the comments below!

Sony Unveils Three Compact Prime Lenses for E-Mount Cameras

02 Apr

The post Sony Unveils Three Compact Prime Lenses for E-Mount Cameras appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

Sony unveils three prime lenses for E-mount cameras

Last week, Sony announced three E-mount lenses:

The FE 24mm f/2.8 G, the FE 40mm f/2.5 G, and the FE 50mm f/2.5 G; all promise to deliver excellent optics in a compact form.

The three lenses will launch this May. Designed as a set, they offer a beautifully wide field of view on the 24mm end for scenic shots and environmental portraits, plus a standard perspective at the 40mm and 50mm focal lengths, perfect for portraits, street photography, and even detail shots.

Sony unveils three prime lenses woman with camera

Sony explains, “The lenses were designed for a wide range of photo and video uses including portraiture, landscape, street photography, and more…With these three dynamic lenses, our customers can capture a wide range of perspectives with the excellent resolution and beautiful bokeh that Sony’s G lenses are known for.”

And while we can’t currently confirm the resolution of these lenses with a hands-on review of our own, sample images look very nice, and Sony’s own tests show tack-sharp results especially when stopped down to f/8. If you’re an APS-C shooter who demands the highest optical quality, or you’re working full frame and want some compact-yet-capable prime lenses, the 24mm f/2.8, 40mm f/2.5, and 50mm f/2.5 will deliver.

Plus, all three lenses offer fast maximum apertures, which translates to lovely bokeh – especially on the 50mm f/2.5, but also on the 40mm f/2.5 and even the 24mm f/2.8 when shooting close-ups.

Of course, f/2.5 and f/2.8 maximum apertures will get you more than just creamy backgrounds. With a wide aperture, you can shoot indoors or at twilight while still maintaining a reasonable ISO, so you can photograph events and night portraits – or record low-light video – and come away with clean results.

Sony also promises “fast, precise AF with excellent tracking performance” and top-notch build quality (all three lenses are dust and moisture resistant).

But while strong build quality, image quality, and focusing do make for a powerful package, even more impressive are the lenses’ compact builds. Travel photographers, street photographers, and videographers will love the pocket-sized design, perfect for on-the-go shooting, long hours behind the camera, and international travel. In fact, all three lenses are identical in size, so you can pack them all without sacrificing weight or space. Check out the lenses next to one another:

Sony unveils three prime lenses

And the prices are surprisingly reasonable. You can grab each lens for just $ 600 USD – not bad at all, given the optics, build quality, and AF capabilities.

So if you’re a Sony shooter in need of a new lens (or two, or three) for travel photography, portrait photography, street photography, or handheld videography, I highly recommend you take a closer look at these options. You can currently preorder the 40mm f/2.5 G here, the 50mm f/2.5 G here, and the 24mm f/2.8 G here.

MonsterAdapter’s new LA-KE1 adapter brings autofocus, aperture control to Pentax K-mount lenses on Sony E-mount cameras

25 Nov

MonsterAdapter, a relatively new player in the lens adapter game, has revealed the details of the LA-KE1, a new adapter that will make it possible to mount Pentax K-mount glass to Sony E-mount mirrorless camera systems.

There isn’t much information available about MonsterAdapter. The company’s Facebook page, which appears to be its only online presence, was created on May 20, 2020, when the company announced the development of the LA-EA4r, a modified version of Sony’s LA-EA4 adapter that expanded functionality and support. MonsterAdapters has since released another adapter, the LA-VE1, which makes it possible to adapt Minolta Vectis V-mount lenses to Sony E-mount mirrorless cameras.

Now, the company is promoting its forthcoming LA-KE1, which it claims is the ‘first of its kind in the world.’ The adapter offers full autofocus, aperture control and EXIF data transfer for Pentax K-mount lenses (KAF, KAF2, KAF3 and KAF4) to Sony E-mount cameras. The adapter uses a pair of motors for turning the screw-drive autofocus in older K-mount lenses.

This not only brings the ability to shoot with Pentax lenses to Sony E-mount cameras, but also enables many of Sony’s AI-assisted focusing modes to be used with the Pentax lenses, new and old. MonsterAdapter says the exact functionality will vary depending on what camera you’re using — noting a more powerful camera likely means more features — but both Human and Animal Eye-AF focus modes should be able to work on adapted glass.

MonsterAdapter also notes that due to the limits of screw-drive lenses, this adapter is best suited for still photographs—not video. In addition to the images of the prototype adapter in this article, SonyAlphaRumors has also shared a hands-on video demonstration of it in action:

No price is given for the LA-KE1 adapter, but it is set to ‘hit the market within this year,’ according to the company’s announcement post. You can keep up with the latest news on MonsterAdapter’s Facebook page.

Sigma announces 85mm F1.4 DG DN Art for E-mount and L-mount

08 Aug

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_9099655589″,”galleryId”:”9099655589″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Sigma has launched its 85mm F1.4 DG DN Art, a fast portrait prime for Sony E and Panasonic/Leica/Sigma L-mount. The lens features 15 elements, including one aspherical and five SLD (special low dispersion). It has 11 aperture blades and its focus unit is driven by a high-speed stepping motor. The minimum focus distance of the 85mm F1.4 is 0.85m (34″) and the maximum magnification is 0.12x.

The lens’ aperture ring has a ‘click switch’, allowing users to choose between ‘clicky’ and smooth rotation, as well as a ‘lock switch’ to prevent accidental operation. As one would expect from a modern lens in Sigma’s ‘Art’ collection, it’s very well built and weather-sealed. Despite that, the lens weighs just 630 grams (1.4 pounds).

The 85mm F1.4 DG DN Art will go on sale later this month for $ 1199.

Press release

Sigma Announces the 85mm F1.4 DG DN | Art Lens, the Definitive Portrait Prime for the Mirrorless Age

  • Fast-aperture full-frame prime lens that is surprisingly compact
  • Dust and Splash-proof construction
  • Completely new optical formula with 5 SLD and 1 Aspherical element
  • Stepping motor optimized for contrast and phase detection autofocus
  • Clicked and de-clicked aperture ring with Iris Ring Lock Switch
  • Available in L-Mount and Sony E-Mount
  • MSRP: $ 1199
  • Anticipated Shipping Date: Late August 2020

Ronkonkoma, NY – August 6, 2020 – Redefining the portrait lens category, the Sigma 85mm F1.4 DG DN | Art lens is a completely new design for full-frame mirrorless cameras, as the “DN” designation indicates. Announced today by Sigma Corporation, this is a complete reinvention of the definitive fast-aperture portrait prime that pairs class-leading optical performance with a compact, dust-and splash-proof design. Offered in both L-Mount and Sony E-Mount, this lens features a completely new optical formula that includes five Special Low Dispersion Elements and one aspherical element for exceptional edge-to-edge image sharpness. This new optical formula also thoroughly corrects aberrations, resulting in visually pleasing images with no color bleed, even at maximum aperture. Plus, the 11-blade rounded diaphragm ensures smooth, attractive bokeh. The 85mm F1.4 DG DN | Art lens is handcrafted to the most exacting optical and mechanical tolerances in Sigma’s Aizu, Japan production facility.

“Briefly put, the Sigma 85mm F1.4 DG DN | Art pairs large-aperture, professional-caliber optical performance with a lightweight, sturdy, and compact body, a combination which has long been difficult to achieve,” reports Mark Amir-Hamzeh, President of Sigma Corporation of America. “This vision is finally realized with the new 85mm F1.4 DG DN | Art lens.”

A smaller focusing lens is paired with the stepping motor, which is optimized for both phase detection and contrast detection autofocus, allowing for this lens to be notably smaller than the 85mm F1.4 DG HSM | Art lens — over an inch shorter and more than a pound lighter than the previous version — while achieving a higher degree of edge-to-edge sharpness from F1.4 and through the entire aperture range.

The Sigma Art line has been consistently redefining both imaging excellence and pleasing in-the-hand experience, and this new lens continues that legacy. Dust and splash-proof design, aluminum and TSC (Thermally Stable Composite) construction, a brass bayonet, plus well-damped switches and rings demonstrate the level of build quality that the Art name represents. Additional benefits include an aperture ring that allows for clicked and de-clicked operation, a programmable AFL button on the lens barrel, and a new Iris Ring Lock Switch that prevents unintended movement of the aperture ring during image capture.

This combination of imaging characteristics, build quality, and compact size for its focal length and aperture combine to make this the class-defining portrait lens for full-frame mirrorless camera systems.

The lens will begin shipping late August 2020. / MSRP: $ 1,199.00

SIGMA 85mm F1.4 DG DN

Designed exclusively for full-frame mirrorless cameras

Redefining the Classic

  1. The record-high performance worthy of the name of 85mm F1.4 | Art
  2. Lightweight & compact – A new perception of F1.4
  3. A full range of functionalities and excellent build quality

Mark a new chapter of the Art line F1.4 in the mirrorless age.

Large-diameter, unparalleled optical performance, compact and lightweight, and high-speed AF ? all in your hand.

The 85mm F1.4 DG DN | Art combines a clear and delicate rendering performance, which is requisite for portrait photography, with beautiful, rich bokeh effects only possible with lenses such as a large-diameter F1.4, at a level that will satisfy both professional and advanced amateur photographers. The focal length of 85mm and significant bokeh effect at F1.4 brightness allow the users’ subjects to stand out in a complementary fashion, which is one of the essences of taking portrait photography, so users can enjoy it to the fullest.

In addition to the fast and consistent AF response, the mirrorless-exclusive design of the 85mm F1.4 DG DN | Art has realized a lightweight and compact lens body that defies convention. And its small body is packed with a range of functionalities, including a dust- and splash-proof structure, supported by an excellent build quality.

The 85mm F1.4 DG DN | Art is SIGMA’s new “ultimate portrait lens” for the mirrorless age. And with it, SIGMA proposes a whole new world of possibilities provided by this “85mm F1.4 lens for everyday use,” thanks to the unprecedented level of portability, free from size- or weight-related limitations.

[Key features]

  1. The record-high performance worthy of the name of 85mm F1.4 | Art

85mm F1.4 is a specification almost synonymous with a portrait lens. With the Art line lenses, SIGMA pursues the highest optical performance possible and has devoted the latest optical design technologies, as well as the production technologies of the Aizu factory, SIGMA’s only production site, to the development of these lenses. The result is a detailed image critical for portrait photography that is achieved at a level that will satisfy both professional and advanced amateur photographers.

In addition to five SLD (Special Low Dispersion) elements and one aspherical lens, the 85mm F1.4 DG DN | Art has incorporated the latest high refractive index glass, which works to thoroughly correct aberrations that cannot be handled by the correction functionality on the camera side. With a particular emphasis given to the correction of axial chromatic aberration, users will enjoy sharp images with no color bleeding, all the way up to the maximum aperture of F1.4.

The high resolving power that covers the entire image from the center to the edges ensures sharpness of the area in focus, and coupled with the significant bokeh effect produced by the F-value of 1.4 brings out the users’ subject in an evocative way.

The numerous rounds of ray-trace simulation, as well as repeated real-world testing, have given the 85mm F1.4 DG DN | Art its ability to minimize ghosting, ensuring clear, sharp images even when shooting in backlit conditions.

With the ability to shoot from the maximum aperture of F1.4 without worrying about image quality, users can focus on the camera operations to realize their artistic expressions, such as the adjustment of exposure and depth of field. This new lens indeed delivers a level of optical performance truly worthy of the name of 85mm F1.4 Art.

  1. Lightweight & compact – A new perception of F1.4

The 85mm F1.4 DG DN | Art weighs 630g/ 22.2oz., with a filter size of 77mm and a body length of 94.1mm/ 3.7in.*. Designed exclusively for mirrorless cameras, it has a “large lens diameter and superb optical performance” and “a lightweight and compact body,” a combination which has long been difficult to achieve.

The AF motor system employs a stepping motor which is optimized for both phase detection AF and contrast AF. Not only does this provide a smooth shooting experience only possible with a mirrorless camera, such as face/eye detection AF, but it has also made the lens body itself much smaller, as the focus lens has been made small to better suit a stepping motor. Furthermore, by making the most of the in-camera aberration correction functionalities, SIGMA was able to concentrate on the correction of aberration that could be handled by the optical system alone, which further contributed to making the lens smaller in size.

With such a lightweight and small body, users can now take out a large-diameter 85mm F1.4 lens for an everyday use such as taking snapshots. The 85mm F1.4 DG DN | Art invites users to enjoy photography in an unconventional way.

* For L-mount.

  1. A full range of functionalities and an excellent build quality

This compact lens is packed with a range of functionalities that will satisfy both professional and advanced amateur photographers.

The 85mm F1.4 DG DN | Art has newly introduced an “Iris ring lock switch.” This prevents from unintended movement of the iris ring during shooting, allowing users to devote their attention to the creation of their image. The “Focus Mode Switch” on the lens body and the “AFL button*” that allows various functions to be assigned from a camera body will also assist users’ shooting.

In addition to the dust- and splash-proof structure, the lens uses materials such as aluminum and TSC (Thermally Stable Composite) where they are best suited, achieving a level of build quality that is worthy of the Art line. In addition to the durability of the body, the lens pursues quality in terms of how users “feel” as well, such as the smooth motion in which each ring or switch works, and the precise hand feeling. The 85mm F1.4 DG DN | Art helps ensure users a smooth shooting experience in every condition.

*Limited to compatible cameras. Also, the functions depend on the camera.

[Additional features]

  • Lens construction: 15 elements in 11 groups, with 5 SLDs and 1 aspherical lens
  • Compatible with high-speed autofocus
  • Compatible with lens-based optical correction

*Only on camera models that support this functionality. Scope of correction varies depending on

  • Iris ring
  • Iris ring click switch
  • Iris ring lock switch

*When turned ON at the position A, the iris ring is locked at A. When turned ON at a position other than A, it is locked within the range between the maximum to minimum apertures and will not engage at the position A.

  • AFL button
  • Focus Mode Switch
  • Dust-and splash-proof
  • Hood with lock
  • Compatible with SIGMA USB DOCK UD-11 (sold separately / for L-Mount only)
  • Designed to minimize flare and ghosting

19 Jun

Sigma has announced the launch of its first ultra telephoto lens specifically for full-frame mirrorless cameras, as well as a pair of teleconverters, a new USB dock and a new mount options for three of its prime Contemporary lenses.

100–400mm F5–6.3 DG DN OS Contemporary

While this new lens might look similar to its previous 100-400mm lens, the 100-400mm F5-6.3 DG DN OS Contemporary has been designed ‘from the ground up for mirrorless camera systems.’ Specifically, the lens will be available in Sony E-mount and L-mount.

It’s designed to cover fulll-frame image sensors and is constructed of 22 elements in 16 groups including one low dispersion element (FLD) and four special low dispersion (SLD) elements. It uses a stepping motor for autofocus, has a nine-blade aperture diaphragm, a minimum aperture range of F22–29 and a 67mm front filter thread. At 100mm it has a minimum focusing distance of 112cm (44”) and at 400mm it has a minimum focusing distance of 160cm (63”). The lens measures in at 86mm (3.4”) diameter, 197mm (7.8”) long and weighs 1,135g (40oz).

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_1628781788″,”galleryId”:”1628781788″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The Sigma 100-400mm F5-6.3 DG DN OS Contemporary is currently available to pre-order for Sony E-mount (Adorama, B&H) and L-mount (Adorama, B&H) for $ 950. The first units should start shipping on July 10.

Sigma Teleconverter TC-1411 and TC-2011

In addition to its mirrorless ultra-zoom, Sigma has also announced two new L-mount teleconverters: the TC-1411 (1.4x) and the TC-2011 (2x). Sigma says these two teleconverters are ‘Designed to complement Sigma’s renowned optical formulas’ and feature a dust- and splash-proof design ‘comparable to that of the Sigma Sports line lenses.’

The TC-1411 (1.4x) and TC-2011 (2x) are currently available to pre-order for $ 400 (Adorama, B&H) and $ 430 (Adorama, B&H), respectively, and should ship on July 10 alongside the 100-400mm F5-6.3 lens.

Sigma USB Dock UD-11

New lenses and teleconverters also mean new docks for updating firmware and adjusting settings. Sigma’s new USB Dock UD-11 models use a USB Type-C connection and are available for Sigma L-mount and Canon EF-M mount mirrorless lenses. As with Sigma’s other docks, the UD-11 models makes it possible to update firmware and customize settings on Sigma lenses with these mounts.

These EF-M and L-Mount docks are also available to pre-order starting today for $ 59 (Adorama, B&H) with an expected shipping date of July 10.

16mm, 30mm, and 56mm F1.4 DC DN Contemporary lenses

Sigma has also announced it’s made its three F1.4 mirrorless lenses available for L-mount camera systems. The 16mm, 30mm, and 56mm F1.4 DC DN Contemporary lenses are identical to their Sony E-mount, Canon EF-M mount and Micro Four Thirds predecessors, and are currently available to pre-order for $ 450 (Adorama, B&H), $ 340 (Adorama, B&H) and $ 480 (Adorama, B&H), respectively, with a July 10 shipping date.

It’s worth mentioning that the only current APS-C cameras that utilize the L-mount, and therefore would be most appropriate for this trio of lenses include Leica’s TL2 and CL mirrorless cameras released in 2017. But for full-frame L-mount users who primarily shoot video, these lenses do make for compact, affordable Super 35 lens options.

Tamron announces versatile 28-200mm F2.8-5.6 zoom lens for E-mount

11 Jun

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_8657748467″,”galleryId”:”8657748467″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Tamron has introduced the 28-200mm F2.8-5.6 Di III RXD zoom lens for full-frame Sony mirrorless bodies. This compact lens is just 11.7cm (4.6″) long and weighs in at 576g (20.3oz).

It features a total of 18 elements, including glass-molded aspherical, hybrid aspherical, extra low-dispersion (known as XLD) and low-dispersion elements. A ‘BBAR’ coating reduces flare and ghosting. The minimum focus distance is just 19.1cm (7.5″) at wide-angle and 80cm (31.5″) at telephoto.

The 28-200 uses a stepping motor for autofocus (‘RXD’ in Tamron-speak) that the company says keeps focus noise to a minimum, making it ideal for video. It is threaded for 67mm filters. The lens is moisture resistant, and the front element’s fluorine coating helps to repel oil and water.

The 28-200mm F2.8-5.6 Di III RXD is expected to go on sale in late June for $ 729, though Tamron notes that the ship date is subject to change due to possible supply chain issues related to COVID-19.

Press release:

Tamron Announces Launch of the World’s First[1] All-In-One Zoom Lens Starting at F2.8 for Sony E-Mount Full-Frame Mirrorless Cameras

28-200mm F/2.8-5.6 Di III RXD (Model A071)

June 10, 2020, Commack, NY – Tamron announces the launch of the 28-200mm F/2.8-5.6 Di III RXD (Model A071), an all-in-one zoom lens for Sony E-mount full-frame mirrorless cameras. The lens is scheduled to be available on June 25 at $ 729. Due to the spread of COVID-19, the release date or the product supply schedule could be delayed.

In 1992, Tamron demonstrated breakthrough innovation with the release of the AF 28-200mm F/3.8-5.6 Aspherical (Model 71D), a compact and lightweight all-in-one zoom lens. The amazingly compact size, light weight and reasonable price made the lens immediately wildly popular with photographers around the world. In the years since, Tamron has continued to be a pioneer in the category, releasing epoch-making all-in-one zooms tailored to each era, including the recent 18-400mm F/3.5-6.3 Di II VC HLD (Model B028) that boasts the world’s highest magnification of 22.2x [2] and which currently enjoys robust sales. The new 28-200mm F2.8-5.6 is a distillation of all Tamron’s accumulated all-in-one zoom expertise and has been specifically developed as an all-in-one zoom for daily use on a full-frame mirrorless camera. Tamron chose Model A071 as the model name in a nod to “71” representing the world’s original compact all-in-one zoom.

The 28-200mm F2.8-5.6 is the first all-in-one-zoom in the world [1] to achieve a maximum aperture of F2.8 at the 28mm wide-angle end. To assure superb optical performance, it features a precise arrangement of special lens elements that accommodate the increasingly high resolutions of today’s digital cameras. Enabling high quality image rendering throughout the zoom range, the lens responds to users’ photographic expressions in powerful style. Moreover, with its 4.6” length, 20.3 oz. weight, and filter diameter of a mere 67mm, the 28-200mm F2.8-5.6 offers excellent portability. When combined with a compact, lightweight full-frame mirrorless camera, it allows photographers to capture virtually every scene they encounter in daily use, travel, sports and nature.

The 28-200mm F2.8-5.6 takes the convenience of an all-in-one zoom (which incorporates various angles of view from wide to telephoto in a single lens) and adds a fast-maximum aperture of F2.8 and superb image quality to enhance the potential for photographic applications. Breaking conventional limitations and broadening the horizons of photographic possibilities, this zoom lens writes a new chapter in the history of the all-in-one zoom lens.

PRODUCT HIGHLIGHTS

1. The world’s first F2.8 all-in-one zoom lens for full-frame mirrorless cameras
A remarkable first for an all-in-one zoom lens: the 28-200mm F2.8-5.6 achieves a fast F2.8 aperture at the 28mm wide-angle end. Additionally, maximum apertures at intermediate zoom ranges are F3.5 at 50mm, F4.5 at 100mm, and F5.6 at 150mm through 200mm. As an unprecedented all-in-one zoom that combines fast aperture with compact size, the 28-200mm F2.8-5.6 delivers greater versatility and usefulness than ever before available.

2. Lightweight and compact size for superior mobility
Tamron’s series of full-frame mirrorless camera lenses, starting with the 28-75mm F2.8 (Model A036), has been developed with the overall goal of balancing high performance with convenience. In addition to the series-standard 67mm filter diameter, and leveraging the camera integrated image stabilization, engineers concentrated on achieving compact size and light weight. Length is just 4.6”, maximum diameter is 74mm, and the weight is a mere 20.3 oz. With a size that offers excellent portability, the lens lightens your load, allowing you to travel comfortably and shoot unencumbered.

3. Uncompromising image quality that lets you focus on creativity
This new zoom lens contains 18 elements in 14 groups. A generous assortment of special lens elements that includes GM (Glass Molded Aspherical), hybrid aspherical, XLD (eXtra Low Dispersion) and LD (Low Dispersion) lens elements is precisely arranged to effectively control chromatic and other aberrations, enabling high resolving power. Meanwhile, the BBAR (Broad-Band Anti-Reflection) Coating provides powerful anti-reflection properties to effectively reduce ghosting and flare, resulting in clear and crisp images. In-camera correction features are utilized to mitigate distortion and shading to achieve uniformly high image quality from edge-to-edge at all zoom settings. Tamron has concentrated all its all-in-one zoom technologies into achieving optical performance that sets a new standard among existing all-in-one zoom lenses. From casual snaps to serious photos, this single lens lets you enjoy a wide range of shooting situations with complete freedom of composition.

4. Superior up-close shooting performance
The 28-200mm F2.8-5.6 delivers superior close-up shooting performance for an all-in-one zoom. At the 28mm wide-angle end the MOD (Minimum Object Distance) is 7.5”, achieving a maximum magnification ratio of 1:3.1. This performance, combined with the fast F2.8 aperture, allows users to move in close so that the subject is large while simultaneously showcasing a beautifully blurred background. Close-up shooting is remarkable at the telephoto end as well, with an MOD of 31.5” and maximum magnification ratio of 1:3.8. Users can capture impressive images with highly blurred backgrounds and create exceptional compositions.

5. The RXD stepping motor unit is exceptionally quiet?
The AF drive incorporates a sensor that accurately detects the position of the lens while the RXD motor unit delivers optimized AF control. This achieves very fast and accurate autofocus operation, allowing users to maintain tack-sharp focus on continuously moving subjects or when filming video. The exceedingly quiet operation is an important advantage because it virtually eliminates extraneous sounds during video recording. In addition, the compact configuration of the RXD AF drive system contributes to the unprecedented size and weight reduction.

6. A full family of superb, compact lenses made especially for mirrorless cameras
The 28-200mm F2.8-5.6 zoom is based on Tamron’s stratagem of creating a series* of lenses for full-frame mirrorless cameras that leverage the characteristics of compact camera bodies. Consequently, photographers can more easily enjoy various combinations of interchangeable lenses. For example, when the Model A071 is combined with the 17-28mm F2.8 (Model A046), the combined weight of the two lenses is less than 35.1 oz. This lightweight, portable zoom set covers everything from wide-angle to telephoto with a zoom range of 17-200mm. Additionally, when combined with a lens from Tamron’s series of fixed focal lenses such as the 20mm F2.8 (Model F050) or 24mm F2.8 (Model F051), the weight is less than 28.2 oz., expanding the possibilities of shooting at the wide-angle end without adding excessive weight or bulk.

All lenses in the series share the common filter diameter of 67mm, thereby eliminating the hassle associated with using different size filters and lens caps. Costly filters (e.g., PL, ND, etc.) can be shared instead of buying separate units for each lens. In this way, Tamron has expanded its series of lenses to make it truly practical to carry multiple lenses at the same time.

7. Moisture-Resistant Construction, Fluorine Coating, and Zoom Lock switch
Seals are located at the lens mount area and other critical locations to deter infiltration of moisture and/or rain drops and afford Moisture-Resistant Construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions. Also, the front surface of the lens element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, moisture or oily fingerprints, allowing for much easier maintenance. Additionally, the handy Zoom Lock switch prevents unwanted barrel extension during transportation.

8. Compatible with main camera-specific features* and functions

Tamron’s new 28-200mm F2.8-5.6 is compatible with many of the advanced features that are specific to certain mirrorless cameras. These include the following:
– Fast Hybrid AF
– Eye AF
– Direct Manual Focus (DMF)
– In-camera lens correction (shading, chromatic aberration, distortion)
– Camera-based lens unit firmware updates

1) Maximum aperture in zoom range among currently available all-in-one interchangeable zoom lenses with a zoom ratio of 7x or higher (As of May 2020: Tamron)
2) Among interchangeable lenses for DSLR cameras (As of May 2017: Tamron)

* Tamron lineup of lenses with 67mm filter diameter for full-frame mirrorless cameras: 28-75mm F/2.8 Di III RXD (Model A036), 17-28mm F/2.8 Di III RXD (Model A046), 20mm/24mm/35mm F/2.8 Di III OSD (Model F050/F051/F053), 70-180mm F/2.8 Di III VXD (Model A056)
