News: Tamron Announces E-Mount Prime Lenses for a Great Price

Last month, Tamron announced three Sony E-mount lenses:

  • The 20mm f/2.8 Di III
  • The 24mm f/2.8 Di III
  • The 35mm f/2.8 Di III

These new E-mount lenses expand the range of glass for Sony mirrorless shooters while making the Sony full-frame lens lineup more affordable for those who can’t justify Sony prices.

In other words: If you’re thinking of switching to Sony but don’t want to pay a premium for full-frame E-mount glass, you have a way in. Each of these lenses is debuting for an ultra-low price of $ 349 USD; compare this to some of Sony’s full-frame E-mount lenses, and you’ll understand why these Tamron offerings are so exciting.

Of course, there’s always a question of optical quality. Can a sub-$ 500 USD lens really be equivalent to Sony’s current 24mm and 35mm glass? The answer is undoubtedly “No,” but not everyone requires the sharpest, fastest, most perfect lenses money can buy. And Tamron has proven themselves to be very capable lens manufacturers in the past, making me think that these lenses will be optically satisfying, even if they can’t go toe-to-toe with some of Sony’s fastest primes.

According to Tamron, we should expect “superb high-resolution performance,” and that “these lenses can be used with complete confidence for a wide range of applications from casual family snaps to serious professional photography.”

While these are bold words from Tamron, I wouldn’t dismiss them out of hand. Plus, Tamron has made sure to include some extra features that make these lenses impressively flexible. For instance, the lenses themselves are relatively small, which makes them ideal for walkaround shooting and travel photography. And all three lenses also offer 1:2 close-focusing capabilities. This won’t get you to true macro magnifications, but you’ll be able to capture some gorgeous close-ups, even as you use the lenses for more general wide-angle photography.

Speaking of wide-angle photography:

For me, the main drawback of this announcement is the lack of focal length diversity. While lenses in the 20-35mm focal length range are undoubtedly useful for a broad range of Sony photographers, I’d have liked to see a telephoto in the mix.

Here’s the bottom line:

For hobbyist and enthusiast photographers who like to work with lightweight wide-angle primes but don’t require f/1.2-f/1.8 apertures, these Tamron lenses are definitely worth a look. The 24mm f/2.8 is available for pre-order, while the 35mm f/2.8 has begun to ship. The 20mm f/2.8 should hit the shelves in January.

What do you think of this announcement? Are you interested in these lenses? Would you have preferred different focal lengths? Share your thoughts in the comments!

Review: Sigma 35mm f1.2 ART Lens for Sony E-Mount

14 Nov

The post Review: Sigma 35mm f1.2 ART Lens for Sony E-Mount appeared first on Digital Photography School. It was authored by Anabel DFlux.

sigma-35mm-f1-2-art-lens-review

Considering the amount of articles I’ve written about shallow depth of field, it is safe to say that anything wider than f/1.8 is my sweet spot. However, Sony has found itself severely lacking in my favorite fast aperture: f/1.2. Well, my friends, Sigma has come to save the day with the brand new Sigma 35mm f1.2 ART Lens for Sony E Mount! It’s the fastest autofocus lens available for Sony mirrorless cameras to date.

I had the pleasure of taking this lens out for a spin on my Sony A7r IV and Sony A7r III and making all of my creamy bokeh dreams come true.

Lens build

Sigma-35mm-f1.2-ART-lens-review

Upon first glance, this lens is large and heavy. Many people wouldn’t realize this is a wide-angle 35mm focal length. The weight is a bit daunting when you use a mirrorless system, especially since one of the big selling points of mirrorless is the small size of the camera. However, the benefit of mirrorless is that all you’re carrying is the weight of the lens, which I don’t mind.

The weight of the Sigma 35mm f/1.2 ART lens is very worthwhile. The following are the reasons why.

In true ART fashion, the lens is solid, sturdy, and what I’d consider shock-resistant. Give it a bump, you’ll see (no, please don’t do that intentionally!). The lens features a dust and splash-proof structure with additional water and oil-repellent coating on the frontmost surface of the lens. I can personally attest to these, having already taken this optic out in some dire conditions. I put lenses through the wringer, and if they can’t survive me, they aren’t a worthy build!

Also, akin to the ART line is the beautiful glass that is vibrant, sharp, clear, and perfect. It’s very reminiscent of the Canon L-series glass, which I was obsessed with, and was thrilled to find similar in the Sigma ART line.

Lens features

Sigma-35mm-f1.2-ART-lens-review

If you’re a native Sony G-Master user who picks up the Sigma 35mm f1.2 ART lens for the first time, you’ll likely see a familiar feature – an aperture ring. This smooth and easy to use manual adjustment of the aperture is quite a useful feature (especially for those who dabble in video and cinema).

Additionally, what’s really interesting about this lens is the ability to click/de-click the aperture ring, allowing complete silence or clicks to let you know you have turned the ring.

The inclusion of the AFL button adds to the lens’s functionality as you can assign it to various operations.

Lens communication

Sigma-35mm-f1.2-ART-lens-review

You don’t invest thousands of dollars on a camera like the Sony Alpha to not use those features, yes? So why would you grab a lens that isn’t compatible? You just don’t. As such, my deal breaker is whether or not the Sigma 35mm f/1.2 ART lens can speak the Alpha’s native tongue (being a non-Sony-brand lens).

Well, the answer is one that I certainly hoped for: The Sigma is fluent in Sony speak!

As one of the first ART lenses designed exclusively with mirrorless in mind, it’s communication with the popular Sony mirrorless system is key (considering the lens only comes in Sony E mount and L mount). All autofocus features (including eye-tracking [human and animal] and AI autofocus) translate brilliantly between the camera body and optics.

Autofocus

Sigma-35mm-f1.2-ART-lens-review

First of all, the autofocus of the Sony Alpha 7r IV and 7r III are just fantastic. Paired with this lens that is great at communicating with the camera, and you have a recipe for winning. My photo sessions have been so much smoother as a result.

Autofocus has been fast, accurate, and a dream. I have had a hard time putting this lens down, and can always find at least one excuse to bring it along for the ride.

I’ve gone as far as to shoot canine sports with it, even though a focal length of 35mm requires me to get closer to my subject than I’d usually like. However, it’s well worth it for that creamy bokeh, because canine agility fields tend to be quite cluttered with obstacles (which makes for a busy frame without the bokeh).

Whether your subject is running at you, away from you, or to the side, there is no discrepancy in autofocus.

Sharpness

Review: Sigma 35mm f1.2 ART Lens for Sony E-Mount

Edge to edge sharpness doesn’t even begin to describe how crystal clear the Sigma 35mm f/1.2 ART lens is. If I closed my eyes, I’d swear I was shooting with Canon L glass. The ART glass has been truly tremendous, especially in recent lens releases.

I found that my subject was just as sharp in the center point as any corners. This is great for those that want to take advantage of the 35mm focal length width and do some off-center frames.

The full-frame capability gives it a further wow factor. When attached to my Sony A7r IV – a 60+ megapixel camera – the images viewed on a massive print-calibrated 4k screen equals some jaw-dropping moments. Pairing tack sharpness with this lens’s visual sharpness results in an image that would make even the ultimate pixel peepers happy. From my own use, I’d say peak sharpness was around f/2.0 – f/2.8.

What you see is what you get, as the sharpness translated to prints beautifully.

Bokeh

Review: Sigma 35mm f1.2 ART Lens for Sony E-Mount

You don’t buy an f1.2 lens not to use it at its widest aperture! It took a bit of effort on my part to ever take it off f/1.2.

The bokeh is creamy, beautiful, and completely effortless. The subject separation is superb, and the client’s response to these magical images is pure bliss. I loved using this lens with cluttered backgrounds as the distraction smoothed away. Even when the aperture is widened to f/2.8, the bokeh continues to be smooth and satisfying.

There is some slight vignetting at the corners, but I quite enjoy this look and add a bit more of it in post-production. Those photographers that are miffed by vignetting may not be too thrilled. However, the 35mm wide focal length does allow for a wee bit of cropping so you can remedy that situation with some corner snips.

The bokeh balls produced with the Sigma 35mm f1.2 lens are very smooth and lovely. You won’t find yourself trapped with no onion-ring bokeh in the editing room, as seen in many other types of similar lenses.

Chromatic aberration

Review: Sigma 35mm f1.2 ART Lens for Sony E-Mount

Much to my positive surprise, I have not experienced any chromatic aberration or fringing with this lens – even on extremely contrasting subjects. This tends to be a common problem with very wide apertures. Whatever magic Sigma did to this particular lens clearly works because I have yet to encounter fringing.

With that said, I’m not saying there isn’t going to be fringing in some peculiar situations, but just that I have not yet personally encountered it. I have encountered fringing immediately with several f/1.4 and f/1.8 lenses from Sony (even the G-Master), unfortunately.

Pros

Review: Sigma 35mm f1.2 ART Lens for Sony E-Mount

  • Fast and beautiful f/1.2 wide aperture.
  • Full-frame lens.
  • Physical aperture ring with click/de-click switch.
  • Excellent communication between Sony E-mount cameras and this Sigma lens.
  • Beautiful creamy bokeh with no onion-ring issues.
  • Fast autofocus and vibrant output.
  • Little to no chromatic aberration.
  • Price is still very competitive, despite being in the four-digit range.

Cons

Sigma-35mm-f1.2-ART-lens-review

  • Heavy, bulky, and large for a 35mm lens (especially on a mirrorless system).
  • Only available in Sony E-Mount and in Sigma/Leica/Panasonic L-Mount (the lens is designed exclusively for mirrorless systems. Some may see this as a con if they don’t own a mirrorless system).

Conclusion

Review: Sigma 35mm f1.2 ART Lens for Sony E-Mount

Sigma 35mm f/1.2 Art Lens Review: Conclusion

My final thought is simple: “this lens will be permanently attached to one of my mirrorless cameras.” The investment is well worth the amount of use you’ll likely get out of this lens, even if you don’t shoot at extremely wide apertures such as f/1.2. I have always found it more worthwhile to invest in lenses that grant you more options and versatility rather than less.

The Sigma 35mm f/1.2 Art Lens can easily become a staple of any kit, with an incredibly vast array of uses from portraits, pets, events, fine art, and everything in between. With the popularity of prime lenses, this one is definitely a top contender.

Tamron 17-28mm F2.8 for Sony E-mount available in July for $900

28 Jun

Tamron has announced pricing for its 17-28mm F2.8 Di III RXD lens for full-frame Sony mirrorless cameras.

The 17-28 is marketed as the ideal companion to Tamron’s excellent 28-75mm lens, adding a useful wideangle range. The 17-28 is 9cm (3.9″) long and weighs in at 420g (14.8oz.). And, since the zoom and focus are internal, it never gets any longer. The lens is sealed against dust and moisture.

The lens has a total of 13 elements, including two low-dispersion and one extra-low-dispersion element. It has a BBAR coating to reduce ghosting and flare and a fluorine coating to resist fingerprints and moisture. It has a minimum working distance of 19cm (7.5″) and maximum magnification of 0.19x. The lens is threaded for 67mm filters, just like the 28-75.

The Tamron 17-28mm F2.8 Di III RXD will ship in late July for $ 900.

Tamron Announces Launch of Large Aperture, Ultra Wide-Angle Zoom Lens for Sony E-Mount Cameras that is Extremely Compact and Lightweight with a Filter Diameter of 67mm

June 28, 2019, Commack, NY – Tamron announces the launch of the 17-28mm F/2.8 Di III RXD (Model A046), a large aperture, ultra-wide-angle lens for Sony E-mount full-frame mirrorless cameras. The Model A046 features a filter diameter of Ø67mm (astonishingly small for a full-frame, large aperture, ultra-wide-angle zoom lens) as well as an unprecedented light weight of 14.8 oz. and diminutive length of 3.9 in. The compact size provides excellent balance on the small profile mirrorless cameras and is easy to carry. The lens will be available July 25 at approximately $ 899 at authorized Tamron USA retailers.

The Model A046 offers a large F/2.8 aperture throughout the entire zoom range and delivers high-resolution and contrast edge-to-edge. The combination of ultra-wide-angle focal length, large constant F/2.8 aperture and an MOD (Minimum Object Distance) of 7.5 in. at the wide-angle end encourages richly expressive and creative photography in a multitude of scenarios.

The new 17-28mm zoom’s AF drive system is powered by the RXD (Rapid eXtra-silent stepping Drive) stepping motor unit that enables it to deliver high-speed, high-precision and superbly quiet operation, making it suitable for shooting virtually noise-free video as well as still photographs.

In addition, the new zoom lens features Moisture-Resistant Construction and a hydrophobic Fluorine Coating that repels fingerprints and dirt. Plus, the Model A046 is fully compatible with various camera-specific features including Fast Hybrid AF and Eye AF. High performance, combined with exceptional portability, make the 17-28mm zoom ideal for daily use.

PRODUCT HIGHLIGHTS

  1. Companion model to the compact, popular Tamron 28-75mm F/2.8 Di III RXD (Model A036) zoom

Sharing the same development concept as the highly esteemed Model A036 that launched in May 2018, the 17-28mm zoom (Model A046) was designed with the top priority of high optical performance in a form factor that is light and compact. Tamron engineers have achieved an unrivaled small size (3.9 in) and light weight (14.8 oz) for a zoom range of 17-28mm. The overall length does not change when zoomed or during focus, thereby creating stable, well balanced operation and excellent mobility. In addition, Model A046 features a filter diameter of just 67mm, very small for an ultra-wide-angle zoom lens. It has the same filter size as its sister lens the Model A036 allowing the use of the same lens cap and filters. The two zooms together create an extremely compact system that covers 17 to 75mm and weighs less than 35.3 oz.

  1. Superb high-resolution performance

The 17-28mm zoom’s optical design consists of 13 lenses in 11 groups, including three aspherical lens elements, two LD (Low Dispersion) lens elements and one XLD (eXtra Low Dispersion) lens element that has properties close to those of fluorite. Together they efficiently suppress chromatic and other aberrations. Additionally, Tamron’s legendary BBAR (Broad-Brand Anti-Reflection) Coating effectively reduces ghosting and flare. Leveraging camera functions*, it provides excellent optical performance matching the latest high-resolution image sensors from edge-to-edge throughout the entire zoom range. The combination of compact size and light weight plus high-resolution performance lets users capture a wide variety of genre including landscapes, architecture and casual snapshot photography.

*When shooting with the camera’s lens correction function enabled.

  1. Extreme close-up capability enables versatile creative expression with ultra-wide-angle zoom

The 17-28mm zoom focuses close. The MOD at the 17mm wide position is 7.5 in (same as Model A036) and the maximum magnification ratio is 1?5.2. At the 28mm end, it achieves the maximum magnification ratio of 1:6 while reaching the MOD of 10.2 in This remarkable performance allows users to create compositions that emphasize perspective (the closer subject is larger and the more distant one is smaller) and that are unique to wide-angle lenses.

  1. 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 pin-sharp focus on continually 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.

  1. Moisture-Resistant Construction and Fluorine Coating

Environmental seals are located at the lens mount area and other critical locations to prevent 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.

  1. Consistent design and operation throughout all Tamron lenses for full-frame mirrorless cameras

Similar to the 28-75mm (Model A036), the 17-28mm (Model A046) has a zoom ring at the front and a focus ring at the rear. Zooming, focusing and other functions are identical in this series to ensure consistent operation. The design is not only beautiful, it is functional as well and features an outer housing hugging the smooth contours of the lens body, deftly worked Luminous Gold brand ring and the precise, rigid metal lens mount. The Luminous Gold brand ring solidifies the characteristic look of a Tamron-branded lens whether on its own or attached to a camera body.

  1. Versatile, exciting combination when paired with the 28-75mm F/2.8 Di III RXD (Model A036)

Two high-performance partners, the 17-28mm combined with the 28-75mm, cover the super-broad range from 17mm ultra wide-angle to 75mm medium telephoto, and maintain excellent speed with an open aperture of F/2.8. The total weight of the two lenses is 34.2 oz, less than 1kg. This compact but potent combo makes the most of the mobility of mirrorless cameras. In addition, both models have a filter diameter of 67mm, so the same filters such as PL (Polarizer) and ND (Neutral Density) may be used with both models, and lens caps are interchangeable.

  1. Compatible with main camera-specific features and functions

Tamron’s new 17-28mm zoom is compatible with many of the advanced features that are specific to certain mirrorless cameras. This includes 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

* Features vary by camera. Please consult your camera’s instruction manual for details.

* As of May, 2019.

Yongnuo reveals YN560TX Pro TTL flash and EF-E II Adapter for Sony E-mount

31 May

Chinese camera gear manufacturer Yongnuo has announced two new products: the EF-E II Adapter for Sony E-mount cameras and the YN560TX Pro TTL flash. The new adapter is available to purchase from online retailers now for $ 99.99 USD, but the YN560TX Pro flash won’t be available to buy until some time in June.

The Yongnuo EF-E II adapter makes EF and EF-S series lenses compatable with Sony E-mount cameras. This model supports AF and mixed-focus systems, and also offers a function key, USB interface (for firmware updates) and a 1/4-in screw hole for tripods.

Voigtländer Nokton 21mm F1.4 Aspherical lens for E-mount officially announced

21 May

Voigtländer has officially announced its 21mm F1.4 Nokton lens for the Sony E mount after showing the concept at the CP+ show in February. The company says the lens will have electronic contacts to transfer EXIF data to the camera and distance information from the lens will help the camera’s image stabilization system. Turning the focus ring on the manual focus lens will activate focus assist modes in the camera, and the aperture ring offers click-less operation for those shooting videos.

The lens is constructed of 13 elements in 11 groups, features a 12-blade aperture diaphragm, has a minimum aperture of F16 and a shortest focus distance of 0.25m. It weighs 560g, measures 70.5mm x 79.5mm (2.78in x 3.13in) and takes a 62mm filter. Below is a (nowhere near full-res) gallery of sample images provided by Voigtländer:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_2385738060″,”galleryId”:”2385738060″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The Voigtländer Nokton 21mm F1.4 will be available in June for ¥165,000 (approx. $ 1,500).

Viltrox announces 85mm F1.8 autofocus lens for Sony E-mount cameras

27 Apr

Chinese camera accessory manufacturer Viltrox has announced a new 85mm F1.8 autofocus lens for Sony E-mount camera systems.

The lens, which has an aperture range of F1.8 to F16, is designed for full-frame Sony cameras, but also works as a 127.5mm equivalent on APS-C cameras. It’s constructed of ten elements in seven groups, including one extra-low dispersion element and four specialty elements made from ‘highly transparent glass,’ which Viltrox says reduces aberrations and improves color rendering. Viltrox also uses an ‘HD Nano’ multi-layer coating on individual elements to minimize ghosting and flares.

A stepping motor (STM) is used to drive the autofocus and the lens features a minimum focusing distance of 80cm (2.62ft). The front filter size is 72mm and integrated contacts power the aperture mechanism and deliver EXIF data to compatible Sony cameras.

Viltrox doesn’t provide the dimensions of the lens, but it weighs 636g (1.4lbs). One of the more interesting elements of the lens is an integrated microUSB port located on the rear metal mount of the lens. This connector is used to upgrade the lens’ firmware, which is currently listed as version 1.01 at launch.

B&H currently has the Viltrox 85mm F1.8 STM Lens for Sony E-mount available to pre-order for $ 379. The expected shipping date is May 6, 2019.

Meike announces an 85mm F1.8 lens for Sony E-mount cameras

06 Mar

Meike has announced the MK 85mm F1.8 lens, a manual focus lens designed for Sony E-mount cameras.

The lens is constructed of nine elements in six groups and features a nine-blade aperture diaphragm. It features a 67mm filter thread and a field of view of 28.5 degrees.

Meike has shared a few sample photos on its product page (shown under the ‘Photo samples’ tab towards the bottom of the page), but they’re not full-resolution and it’s not clear what Sony E-mount camera they were shot with.1

The lens is currently listed on Amazon, but pricing and availability aren’t yet mentioned.

1 We try to share sample photos in our articles when provided, but Meike inexplicably decided to provide their sample images as one long image, which measures 790 x 16,187 pixels.
