Kamlan 28mm F1.4 for APS-C sample gallery

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_6947377912″,”galleryId”:”6947377912″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The Kamlan 28mm F1.4 is an all-manual prime lens for APS-C (and Micro Four Thirds) mirrorless cameras. Following a successful Kickstarter campaign, it’ll go on sale to the public for $ 200, and after a bit of shooting we’d say that’s not a bad deal. It boasts a solid feel, and rings are smooth to turn and feel well-damped. A lack of optical coatings creates some unusual effects when shooting into the sun, and the lens provides no electronic communication with the attached camera body. That said, it’s hard to argue with a $ 200 price tag.

Take a look through our gallery to see what this budget-priced prime can do on Fujifilm and Sony bodies.

Samyang releases 85mm F1.4 AF lens for Canon DSLRs

18 Jun

Exactly one week after dropping its 24mm F2.8 AF lens for full-frame Sony cameras, Samyang is back at it again. Today, Samyang announced the release of a new 85mm F1.4 AF lens for Canon DSLRs.

The telephoto prime is yet another addition in Samyang’s growing portfolio of autofocus lenses. This lens in particular uses an upgraded dual-motor system to deliver faster, more accurate autofocus performance, according to Samyang. The minimum focusing distance is 90cm/35.43in, roughly 5cm more than Canon’s 85mm F1.4 IS USM lens, which has a minimum focusing distance of 85cm/33.46in.

The Samyang AF 85mm F1.4 EF lens weighs 485g/1.07lbs and measures in at 72mm long without the lens hood or rear cap. It’s constructed of nine optical elements in seven groups, including hybrid aspherical elements and an “ultra multi coating” designed to eliminate flares and ghosting. Samyang has also included weather-sealing, which should make it a little more robust in tough environments.

The Samyang AF 85mm F1.4 EF lens, which sells under the Rokinon brand name in the United States, will be available in July 2018 for £599.99 (~$ 800). This puts it at roughly half the price of Canon’s 85mm F1.4 IS USM lens, which retails for $ 1,600.

More information released on Yongnuo YN 50mm F1.4 II

02 Jun

Yongnuo has unveiled a new version of its 50mm F1.4 lens – the upcoming YN 50mm F1.4 II. The new model follows an update to the company’s 50mm F1.8 offering (predictably called the 50mm F1.8 II), giving photographers a new and inexpensive alternative to Canon’s venerable EF 50mm F1.4.

Yongnuo’s new lens features a USB port for firmware updates, support for live view focusing, electromagnetic aperture, and a new external design. The company emphasizes the 50mm F1.4 II’s bokeh capabilities.

The YN 50mm F1.4 II features 9 elements in 7 groups, electromagnetic aperture with support for M/Av/Tv/P/B modes, gold-plated contacts and a metal mount, glass optics with a multilayer coating for better light transmission with controlled glares/ghosting, as well as both manual and auto focus, a focus distance indictor, and the same DC motor drive system found in the original model.

The Hong Kong company detailed the new lens on its website, but pricing and availability have yet to be announced.

Kamlan 28mm F1.4 APS-C lens unveiled with upcoming Kickstarter campaign

01 Jun

Chinese company Machang Optics is preparing to launch its new Kamlan 28mm F1.4 MFT lens on Kickstarter, where the company currently has its project listed in draft. The latest Kamlan lens is billed as an inexpensive alternative to pricier lenses while offering the same “premium optical quality” paired with a versatile focal length, super-low chromatic aberration, and a full metallic body.

The Kamlan 28mm F1.4 APS-C lens features 7 groups in 8 elements, 11 circular blades, 0.25m minimum focusing distance, 0.15x max magnification, manual focus, 52mm filter thread, and a 348g / 12oz weight. Machang Optics says the manual aperture ring is de-clicked for smooth changes during video recording.

Despite its budget-tier cost, Machang claims its new Kamlan lens provides a “neutral, accurate color rendition” and excellent center sharpness. The company plans to offer its latest model in Canon EOS M, Micro Four Thirds, Sony E, and Fuji XF mounts.

Once live, Kickstarter backers will able to pledge $ 149 USD to the campaign for a single Kamlan 28mm F1.4 lens. Shipping to backers is expected to start in August, and the lens has an anticipated $ 199 USD retail price.

In addition to its new 28mm offering, Machang has revealed a product timeline for future lenses it plans to launch: 21mm F1.8 APS-C, 50mm F1.1 Mark2, 32mm F1.3 APS-C, and 15mm F1.8 APS-C. The company indicates it will launch these new lenses later this year.

Sigma announces price and ship date of 105mm F1.4 ‘bokeh master’ Art lens

26 May

Sigma’s special ‘bokeh master’ 105mm F1.4 DG HSM Art lens made quite a splash when it was first announced back in February, and now Sigma is finally revealing when it will ship and how much it will cost. If you’re in the market for this behemoth of a lens—seriously, we got a hands on at CP+… it’s huge—for either Nikon, Canon, or Sigma mounts, you’ll have to pony up $ 1,600 USD and wait until “late June” to get it.

For Canon and Sigma shooters, this is a whole new speed of lens that you’ve never had access to before. For Nikon shooters, it’s an opportunity to save $ 600 on the Nikon 105mm F1.4E ED lens, which is currently going for $ 2,200.

To learn more about this lens, check out our hands-on coverage from CP+, read the full pricing and availability press release below, or visit the Sigma website.

Press Release

Sigma Announces Pricing and Availability for Its 105mm F1.4 DG HSM Art Lens

The “Bokeh Master” will begin shipping in Canon, Nikon and Sigma mounts in late June for a retail price of $ 1,599.00 USD

Ronkonkoma, NY – May 25, 2018 – Sigma Corporation of America, a leading still photo and cinema lens, camera, flash and accessory manufacturer, today announced that its 105mm F1.4 DG HSM Art lens will be available in Canon, Nikon and Sigma camera mounts in late June for $ 1,599.00 USD through authorized US dealers. The Sony E-mount availability will be announced later.

The “Bokeh Master” with Longest Focal Length Among Sigma Wide-Aperture F1.4 Art Lenses

The Sigma 105mm F1.4 DG HSM Art is the ninth lens in the Sigma F1.4 line-up designed for full-frame cameras. To combine outstanding wide-aperture, mid-telephoto performance with F1.4 brightness at maximum aperture, this lens incorporates 17 optical elements in 12 groups, including three FLD glass elements, two SLD glass elements and one aspherical lens element. This optical setup minimizes axial chromatic aberration to deliver ultra high resolution along with ample peripheral light volume, which minimizes vignetting. As a result, the area in focus is extremely sharp, while the out-of-focus area features a beautiful bokeh effect with highly natural colors, making this a desired lens for portrait photography. The optical design also minimizes sagittal coma flare, making it an excellent choice for capturing starry skies.

Featuring the Sports line level dust- and splash-proof design, this lens can be used in varying weather conditions. The high-speed, high-accuracy autofocus helps photographers react in an instant to capture those special moments.

Other lens highlights include carbon fiber reinforced plastic hood for durability and compatibility of the Canon mount lens with the Canon Lens Aberration Correction function.

CP+ 2018: Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

04 Mar

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

Although the changes separating the K-1 Mark II from its predecessor are small in number, the new model occupies a big chunk of the Ricoh-Pentax booth at this year’s CP+ show in Japan. We were able not only to get our hands on the camera, but also the company’s upcoming D FA* 50mm F1.4 SDM AW that we’d only previously seen behind glass.

And though we couldn’t save any pictures taken with the camera, we got a chance to quickly try out the maximum ISO value of 819,200 and hand-held Pixel Shift mode – read on to find our impressions.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

Ergonomically, the K-1 Mark II is to all intents and purposes identical to the K-1, and the control scheme is identical its predecessor. With a UI that’s well-sorted and an impressive amount of direct controls, this isn’t a bad thing.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

Indeed, the only noticeable physical change to the body is the name on the front of the camera, and existing K-1 users that send their cameras in for the $ 550 upgrade will have the new name painted on their older models. Functionally, we’re told that an upgraded K-1 and a factory-fresh K-1 Mark II will be identical.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

Thanks to the new ‘accelerator’ in the imaging pipeline, the K-1 Mark II is able to shoot at ISO 819200, which is an increase of two stops compared with the original K-1’s previous maximum value of 204800. As you might expect, the one sample shot we took at this value showed a very high amount of noise, but it’s entirely possible that more moderately high values will show improvement over the original K-1. This is something we’ll be looking at very closely when we get a production K-1 II in for testing.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

The really big change for the K-1 II is the hand-held Pixel Shift mode, with the menu option shown here. We did a trial shot with the D FA* 50mm F1.4, and were pleasantly surprised by the sharpness of the result – despite shooting at a moderate focal length, there wasn’t any blur from hand-shake to be seen.

Unfortunately, your valuable time is the price your pay for this functionality; while the actual exposures are captured rapidly, the camera takes roughly 20-25 seconds to process the final image, during which time it is effectively locked. Still, we’re impressed by the possibilities of this new Pixel Shift implementation.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

And now, on to the HD Pentax-D FA* 50mm F1.4 SDM AW lens. This is Pentax’s first new prime lens to be developed since the introduction of the K-1 two years ago, and it feels like a really premium piece of kit. The nitty gritty details on the lens are still thin – we still don’t know the optical formula, for instance – but this pre-production model appeared fully functional.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

The ‘D FA*’ label designates this as a flagship lens for Pentax, and it certainly feels like it. It’s quite heavy and solid-feeling, but it balances well on the K-1 II thanks to the camera’s good-sized grip.

Focusing is taken care of internally and with a silent motor, and though it isn’t what we’d call ‘lightning fast,’ we would say it’s on par with other manufacturers’ wide-aperture prime lens offerings.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

The 50mm F1.4’s ‘WR’ label stands for ‘weather resistant,’ which is made most visible by the bright red gasket on the rear of the lens. Although we don’t know the full extent of the sealing, we’d surmise there are a number of other seals against both dust and moisture incursion throughout the rest of the lens.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

Handling on the D FA* 50mm F1.4 is straightforward, with only an autofocus switch and a broad, well-textured manual focus ring. The distance scale is likely to be appreciated by users preferring manual focus, and the lens can focus down to 0.4m or 15.75 inches.

Hands-on with the Pentax K-1 Mark II and D FA* 50mm F1.4

We’re really excited to get both the new D FA* 50mm F1.4 and the K-1 II into the DPReview offices to see what this combination can do. The K-1 II will be available in April, 2018 for $ 1999.95 body-only.

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

03 Mar

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

Tokina released two lenses in advance of the CP+ 2018 show in Yokohama, and we had a chance to stop by their booth and get a closer look. First up is a premium 50mm F1.4 prime, the first in a new series of ‘Opera’ lenses designed for high performance on DSLR cameras.

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

As you can see, the 50mm F1.4 is fairly large. The build quality is extremely solid, fit and finish is excellent and the focus ring is nicely damped.

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

This new lens is just a prototype, and we unfortunately weren’t given any information on the lens’ optical construction or pricing. But the press release does state that the new lens lineup’s name, ‘Opera,’ was chosen because the company hopes to help photographers create photographic works of art.

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

The 50mm F1.4 Opera features a degree of weather-sealing, including a gasket around the lens mount to help prevent dust and moisture incursion. It’s slated to be available in European and Asian markets in the summer of 2018.

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

The E-Mount FíRIN 20mm F2 FE AF is a different beast altogether. Designed for mirrorless cameras, the 20mm F2 AF is a followup to Tokina’s existing manual focus lens of the same specification.

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

Those specifications include 13 lens elements in 11 groups; three of those elements are Super-low Dispersion, and two are aspherical. Despite this, the FíRIN remains compact and lightweight, with a heft of 464 grams. Unfortunately for those that enjoy manual focus, there is no distance scale.

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

The front of the lens accommodates a bayonet-style hood and 62mm filters. The 20mm F2 AF has a nine-bladed aperture diaphragm, and the closest focus distance is 0.28m or 0.9 feet.

CP+ 2018: Hands-on with Tokina’s 50mm F1.4 and 20mm F2

It’s best to take care when using this lens in inclement weather, as there is no rear gasket nor claims of weather or moisture sealing. Despite this, the FíRIN 20mm F2 looks very promising.

The lens will tentatively be available in Japan by the end of April and the rest of the world in May. Pricing information has yet to be announced.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’ & 70mm macro

01 Mar

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

Sigma’s new 105mm F1.4 DG HSM is a beast, weighing in at 1.6 kilos. We’re at the CP+ tradeshow in Yokohama, Japan, where we just got our hands on what Sigma is calling the ‘bokeh master’.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

Even without the hood, the new 105mm is a large lens, with a front filter diameter of 105mm. It’s not particularly long, but as you can see from this shot, which shows the lens mounted on a Canon EOS 6D, it has a very wide diameter of 116mm (4.6 inches). The large tripod ring is included, and can be removed for hand-held shooting.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

With the hood attached, the 105mm gets even larger.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

The new 105mm is unstabilized, which means that the only controls on the lens are an AF/MF switch and a very broad, wide-diameter focus ring. Manual focus is a luxurious experience on all of Sigma’s ‘Art’ series and this lens is no different. Judging purely from our brief experience on the show floor, autofocus speed is similar to the 85mm F1.4: smooth and positive without being as quick and snappy as lenses with fewer pieces of glass to move around.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

And there is a lot of glass inside the 105mm. The new lens comprises 17 elements in 12 groups, including three FLD glass elements, two SLD glass elements, and one aspherical element.

Sigma claims that the lens creates a beautiful bokeh effect, and the well-controlled sagittal coma should make it excellent for capturing ‘starry skies’. A 105mm wouldn’t be our first choice for astrophotography, but we can’t wait to get hold of a shootable sample, and see what it can do.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

Also unveiled at the show was a new macro lens, – a first for the Art range. The 70mm F2.8 DG Macro offers true 1:1 reproduction, and a dust and splash-proof construction.

The lens features an extending, floating, two-group focus mechanism. Optical construction incorporates two FLD glass elements, two SLD glass elements, and one element with ‘a high rate of anomalous partial dispersion and a high index of refraction’. This should minimize axial chromatic aberration. Sigma claims that two aspherical elements ensure ‘razor-sharp’ images at close focusing distances.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

The 70mm macro is a pretty compact short-tele lens when focused at infinity, but gets bigger when the included hood is attached. The front filter diameter is a modest 49mm. Three focus limits can be set, for reducing autofocus ‘hunting’ at short working distances.

CP+ 2018: Hands-on with Sigma 105mm F1.4 Art ‘bokeh master’

When the lens is racked to its minimum focus distance of 26cm (10.2 inches) the lens itself grows considerably in size (but the hood stays put). Focus is ‘focus by wire’.

At 515g (18 oz) it’s reasonably lightweight, and balances well on our A7R III (with an adapter). We got our hands on a Canon-mount version, but the 70mm F2.8 is also available in Sony FE mount natively.

Tokina unveils ‘top premium’ Opera 50mm F1.4 FF lens for Canon and Nikon

01 Mar

Tokina has officially announced the Opera 50mm F1.4 FF lens for Canon EF and Nikon F mounts that was leaked last week. The lens—part of Tokina’s new ‘Opera’ series designed for ‘high-spec full-frame DSLR cameras’—will arrive on store shelves in Summer of 2018, and a prototype is being shown off this week at CP+ in Japan.

This lens, and the Opera series in general, are being billed as Tokina’s ‘premium’ line—sort of like the Sigma Art series. In fact, Tokina goes out of its way to connect the term Opera with ‘Art’ in its press release. But marketing word choice aside, Tokina promises that Opera branded lenses will be “designed to perfectly match recent high-spec full-frame DSLR cameras, which keep requiring high quality optics.”

The Opera 50mm F1.4 FF is the first in this lineup, and already Tokina has put more tech into the lens than you’re probably used to from the third-party manufacturer. The lens boasts a ring-shaped ultrasonic AF motor, weather sealing to protect internals from dust and moisture, an electric diaphragm mechanism for the Nikon version (a first for Tokina), and a focus ring that turns the same direction as your native Nikon and Canon glass.

Unfortunately, Tokina hasn’t revealed one of the most important details yet: price. But with the official release scheduled for summer 2018, it won’t be long before we find out if (or by how much) Tokina has undercut Nikon and Canon’s 50mm F1.4 options.

Press Release

Kenko Tokina Co., LTD. is Proud to Announce the New Tokina Opera 50mm F1.4 FF, a Premium Full-Frame Lens for High-End DSLR Cameras

February 28, 2018

About opera series

With the debut of opera 50mm F1.4 FF we are launching a new series of next generation premium full-frame lenses for high-end DSLR cameras called “opera” series.

Opera series is designed to perfectly match recent high-spec full-frame DSLR cameras, which keep requiring high quality optics to be used with. In addition to originally high-valued Tokina AT-X series, this new opera series is positioned as top premium series of full-frame size lenses and will be further expanded with other lenses of related specifications and performance.

In modern society the word “opera” is commonly used to express general genres of stage art. In Italian it means work or work of art. As an omitted art genre definition opera comes from “opera musicale” that means a piece of music work. In Latin opera comes from “opus” and in contemporary language “magnum opus”, “opera magna” still has a meaning of “great literary, artistic or intellectual work”. We chose the name “opera” for a new premium full-frame DSLR lens series thinking of a lens that will help photographer in creating real “work of art”.

About the product

The debuting premium full-frame lens for high-end DSLR cameras in opera series is 50mm F1.4 FF (FF – Full-Frame). Designed for full-frame format DSLR cameras, opera 50mm F1.4 FF adopts a ring-shaped ultrasonic motor for autofocus drive module. Weather sealing prevents from dust and moisture to come inside the lens body. For the first time in Tokina line up Nikon mount model incorporates an electric diaphragm mechanism. The direction of the focus ring rotation fits the genuine Nikon and Canon lens.

Mounts: Nikon F, Canon EF

Sensor size: full frame format

About sales release

Sales release: summer 2018

A prototype of Tokina opera 50mm F1.4 FF will be displayed at CP+2018 Kenko Tokina booth location: Exhibition Hall(1F), booth # G-57

Sigma unveils 105mm F1.4 Art ‘bokeh master’

27 Feb

The Sigma 105mm F1.4 DG HSM is the longest F1.4 lens in the Art series to date, comprising 17 elements in 12 groups. It is, of course, dust- and splash-resistant, and includes an Arca-Swiss tripod collar. Sigma boasts that the 105mm delivers ‘unsurpassed F1.4 performance’ and ‘exceptional peripheral brightness.’ No pricing or availability is given at announcement.

SIGMA 105mm F1.4 DG HSM

Introducing the “bokeh master”—featuring incredible resolution and designed for full-frame sensors, this is the longest focal length of the Art line’s F1.4 lenses

1. Optical system delivering unsurpassed F1.4 performance

2. Exceptional peripheral brightness

3. Professional specifications

4. Ease-of-use specifications

5. Compatible with full-frame Sony E-mount cameras

6. Compatible with Canon Lens Aberration Correction Launch: TBD Accessory: Case, Cover Hood (LH1113-01), tripod socket (TS-111), protective cover (PT-21) Available AF mounts: SIGMA, Nikon, Canon, and Sony E-mount Note: Appearance and specifications are subject to change without notice.

Leading the way in F1.4 brightness
Since introducing its first SIGMA Global Vision F1.4 lens in 2012, the 35mm F1.4 DG HSM | Art, SIGMA has been adding wide-aperture F1.4 options to the lineup. Now, with the introduction of the new 105mm F1.4 DG HSM | Art, SIGMA offers a total of nine lenses with F1.4 brightness, including six for full-frame cameras and three for APS-C cameras. SIGMA has designed all of these lenses to offer minimal optical aberration and deliver incredible resolution and stunning contrast. Boasting the longest focal length of the F1.4 Art line lenses, the new lens combines outstanding resolution with a beautiful bokeh effect. Designed with great care to ensure that both the in-focus and out-of-focus areas of the photograph are equally satisfying to the eye, this lens is truly a “bokeh master.” The SIGMA 105mm F1.4 DG HSM | Art has earned its place as the flagship of the F1.4 Art line lenses, prioritizing image quality above all to fulfill the promise of the line, delivering truly amazing optical performance.

Key features

1. Optical system delivering unsurpassed F1.4 performance
In order to combine outstanding wide-aperture, mid-telephoto performance with F1.4 brightness at maximum aperture, this lens incorporates 17 optical elements in 12 groups—an uncommonly large number of elements for a prime lens. By including three FLD glass elements, two SLD glass elements, and one aspherical lens element, the optical system minimizes axial chromatic aberration to deliver extremely high resolution along with ample peripheral light volume. The area in focus is extremely sharp, while the area out of focus features a beautiful bokeh effect with highly natural colors, making this lens a powerful choice for portrait photography. The optical system also minimizes sagittal coma flare, making this lens excellent for capturing starry skies.

2. Exceptional peripheral brightness
The most effective method of ensuring ample light is to maximize the diameter of the first element of the optical system. With its large filter diameter of 105mm, the SIGMA 105mm F1.4 DG HSM | Art delivers a significantly greater volume of peripheral light than other lenses in its class. Minimizing vignetting while offering a beautiful bokeh effect, this lens is ideal for portrait photography.

3. Professional specifications
Like SIGMA’s Sports line lenses, the 105mm F1.4 DG HSM | Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection*, manual focus ring, cover connection, and other areas, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy. The high-speed, high-accuracy autofocus helps photographers react in an instant to get those special shots.
*SIGMA mount lens does not include sealing, since sealing is present on compatible SIGMA cameras.

4. Ease-of-use specifications
Instead of conventional ABS plastic, the exclusive lens hood features CFRP (carbon fiber reinforced plastic), a light but strong material used in the interior and exterior fittings of aircraft, among many other applications. The removable Arca-Swiss tripod socket is compatible with Arca-Swiss platforms and clamps, and its exclusive protective cover makes the lens easier to carry and use when shooting hand-held.

5. Compatible with full-frame Sony E-mount cameras The Sony E-mount version of this lens is compatible with Sony mirrorless cameras and contains the same optical system as the versions for other mounts. SIGMA MOUNT CONVERTER MC-11 is not required, as the lens performs the same functions as the converter, including in-camera image stabilization and in-camera lens aberration correction. In addition, the lens is compatible with Sony’s Continuous AF, which is not available via MOUNT CONVERTER MC-11. SIGMA plans eventually to offer Sony E-mount versions of every full-frame prime lens currently available in the Art line, from 14mm to 135mm.
Note: This product is developed, manufactured and sold based on the specifications of E-mount which was disclosed by Sony Corporation under the license agreement with Sony Corporation.

6. Compatible with Canon Lens Aberration Correction
The Canon mount version of this lens is compatible with the Canon Lens Aberration Correction function.* Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
*Function not available on all Canon cameras. Available corrections may vary depending on the Canon camera model.

Other features

  • Rounded diaphragm
  • Fast AF with full-time manual override*
    *The operation of full-time MF may vary based on mount type.
  • Compatible with SIGMA Mount Converter MC-11 Note: SIGMA and Canon mount lens
  • Available SIGMA USB DOCK makes customization and flexible adjustment possible* *Not available for Sony E-mount lens
  • Available Mount Conversion Service
