Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

22 Jun

In this quick review of the Sigma 135mm f1.8 Art Lens, I will go over some of its features and give you my overall impression of this lens.

Photographers like gear

I belong to several photography groups, both online as well as within my local area, and often times when we meet, we end up talking about our gear. Conversations typically revolve around the gear we have, what we would like to have, and what we want to sell off. On several occasions, I have heard my fellow photographers talk about the Sigma Art series of lenses. They always start the conversation with, “Oh, I absolutely love my Sigma Art lens. The bokeh is so dreamy!” Now, I am a Canon shooter – always have been and always will be. But that does not mean that every once in a while, I don’t like to test out gear from other companies to compare performance, specifications, and price.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

The Sigma 135mm F1.8 DG HSM Art Lens comes with a case and a lens hood.

So when I had the opportunity to test out the Sigma 135mm 1.8 DG HSM Art lens, I jumped at the chance. I spent about three weeks with this lens and used it for a variety of photography assignments – both indoors and outdoors. Here is my review based on my personal experiences with this lens.

Technical Specifications

As per Sigma’s website, the Sigma 135mm F1.8 DG HSM Art is a medium range telephoto prime lens designed for modern high-megapixel DSLRs. A new large Hyper Sonic Motor (HSM) delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. This state-of-the-art prime lens touts a dust and splash proof mount for guaranteed performance in any condition and its large 1.8 aperture allows for more creative control over imagery.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

The Sigma 135mm F1.8 DG HSM Art Lens attached to my Canon 1V film camera.

My telephoto lens of choice is my Canon EF 70-200L lens. It’s heavy and bulky but gives me some of the best picture quality in its class. Compared to that lens, the 135mm felt lightweight and comfortable to carry around all day. Being a fixed lens, there are no moving parts, unlike the zoom ring on the 70-200mm. While this meant that I had to move around to get shots at various distances, it was not an inconvenience. I just used pretended to have a zoom lens by moving my feet!

The lens looks very sharp and clean. The smooth matte black finish of the lens gives it a certain visual appeal. The build quality is very clean and it feels like a solid piece of glass. The lens is a little heavy (at about 2.56 pounds or 1.2 kg) but if you are used to walking around with other telephoto lenses, it’s not any different compared to using those.

Sharpness of the Sigma 135mm F1.8 Art Lens

The legendary quality of having the dreamiest bokeh is very true with this lens. It is super sharp even when shooting absolutely wide open. I typically shoot very wide opened with all my Canon L-lenses which fits my style of photography. The aperture of f/2.0 is my personal sweet spot – the one that I really trust to give me a shallow depth of field and dreamy bokeh (blurry background). This lens did not disappoint at my favorite f-stop.

But even at f/1.8 (the widest aperture on the Sigma 135mm), the lens was tack sharp with very shallow depth of field. Once it was stopped down to f/16, there was some softness on the edges of the frame but it’s not very prominent. With a lens of this quality, the best aperture would be between f/1.8 to f/4 (in my opinion) to get the best of the shallow depth of field and bokeh that we all love.

Shot at ISO 200, f/1.8 – wide open – look at that dreamy bokeh.

ISO 200 at f/2.0

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

ISO 200 at f/9 – more of the entire scene is clear and visible – with a wider (deeper) depth of field here.

Vignetting

The Sigma 135mm at f/1.8 Art Lens showed slight edge vignetting when shot wide open. But for my style of photography, it’s minimal and nothing I could not fix in post-processing. I was very impressed with the number of tack sharp images that I could keep even when I used the lens completely wide open at f/1.8.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

The image above left was shot at ISO 200, f/2.0 and on the right, the same scene was shot at ISO 200, f/9. There is no visible softness or vignetting at either aperture. The bokeh at f/2.0 is so dreamy (shallow depth of field) and at f/9 more of the background is visible.

Autofocus

The Sigma 135mm has an electronic hypersonic motor. This makes the autofocus very fast and smooth. I found that the lens locked focus easily and did not hunt while focusing. The AF motor was also relatively quiet and smooth as compared to other telephoto lenses like the Canon 85mm f/1.2L II USM that is really slow while hunting for focus in the AF mode.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

While hiking my two boys decided they would lead the pack. I really wanted to capture this independent streak and both images are shot less than 2 seconds apart. The Sigma 135mm had no problems tracking focus as they moved up the trail. Both images were shot at ISO 200, f/2.0 and both have the subjects tack sharp and in focus in spite of the movement.

Macro capabilities

While the Sigma 135mm is not described as a macro lens, it did offer 0.2x magnification with a minimum focusing distance of just under three feet. Since I have a dedicated macro lens that I use for my detail shots, I did not pay much attention to this feature. However, in a pinch, this lens could be used to provide some magnification.

Karthika Gupta Memorable Jaunts DPS Article - Sigma 135mm lens review-11

The 135mm zoom was a little tight when I had to take in-studio headshots but once I got the focus locked, it turned out beautifully. Both images were shot at f/2.0 ISO 640, 1/125th.

Summary

Overall I was really very impressed with the Sigma 135mm 1.8 DG HSM Art lens. It is a superbly built piece of gear that was incredibly fast, easy to carry, handle, and use.

The only thing I needed to get used to was the fact that it was a prime lens and not a zoom, unlike my favorite 70-200mm telephoto lens. This meant I had to move around to get shots at different angles and different focal lengths, but I don’t consider that a con. Instead, I feel that shooting with a prime lens makes you more careful and thoughtful about your compositions since you have to physically move around to get a diverse range of shots.

The Sigma 135mm lens is definitely something to look into if you are in the market for a good quality telephoto lens.

Zeiss formally announces Batis 135mm F2.8

06 Apr

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_1805444245″,”galleryId”:”1805444245″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Zeiss has announced a new medium telephoto full-frame Batis lens for Sony E mount: the Batis 2.8/135. The Apo Sonnar optical design comprises of 14 elements in 11 groups inside a smooth metal body with an OLED display with distance and depth of field information. As with all lenses in the Batis line, it offers AF, and a robust build with weather-sealing. It also features image stabilization, like the Batis 85mm.

The lens will be available in May 2017 with an MSRP of $ 1,999.

Press Release:

The new ZEISS Batis 2.8/135 is the first 135 mm AF focal length for mirrorless full-frame cameras from Sony

OBERKOCHEN/Germany, 05/04/2017.

Fans of Sony’s mirrorless full-frame cameras have a reason to smile: ZEISS has added a further tele lens focal length to its ZEISS Batis lens family. The new ZEISS Batis 2.8/135 is the first 135 mm AF focal length for Sony’s Alpha 7 system with E-mount. Like all lenses from the ZEISS Batis range, this new addition is equipped with fast and precise autofocus. To avoid shaking, which can occur very easily with tele lenses, an optical image stabilizer has also been incorporated into the design. The ZEISS Batis 2.8/135 proves it worth particularly in portrait photography: “The tele focal length means the subject can stand out nicely against the blurred background”, says Product Manager Michael Pollmann from ZEISS. “The bokeh works very well indeed, and the optical design – an Apo Sonnar – ensures outstanding images time and again.” The new ZEISS Batis could also be a great option for event and wedding photography.

“Compact, lightweight, top quality”

“The advantage of Sony’s mirrorless full-frame system is that despite its compact size, it delivers exceptional image quality,” says Pollmann. ZEISS has continued to bring the design of the ZEISS Batis 2.8/135 into line with the needs of Sony photographers. “It was important to build a comparably handy lens – in spite of the rather long focal length. We made a conscious decision to strike a balance between compactness, weight and light intensity.”

OLED display visualizes depth of focus

Like all ZEISS Batis lenses, this latest addition features an OLED display that enables precise visualization of the depth of field. So you can be sure that the image is in focus in all the right places. The metal housing gives the lens its robust and durable character. ZEISS assures us that its dust and dirt shield means photo shoots in poor weather are a walk in the park.

The image quality leaves nothing to be desired: “We have put a lot of effort into the optical design and into correcting our lenses,” says Pollmann. “For example, we are experimenting with special types of glass in order to rule out as many kinds of image errors as possible. We have thus been able to ensure corrected chromatic aberration in the ZEISS Batis 2.8/135 so that we have virtually no image errors.” 14 lenses have been built into 11 groups in the camera lens.

Price and availability

The ZEISS Batis 2.8/135 will be available from specialist dealers starting May 2017 and will retail at 1,999 euros incl. 19 percent sales tax (RRP).

The ‘Crapinon’ is a 135mm lens made from discarded parts

04 Apr

You know what they say about one man’s trash. Well, lens enthusiast and freelance video producer Mathieu Stern took the phrase to heart when he found an old lens tube at his local flea market. It was in a box of unsold items destined for the trash when he rescued it and gave it a new life. With the addition of an ND M42 to NEX adapter, M42 tubes and a couple of rubber bands, the ‘Crapinon 135mm’ was born.

Sigma announces 14mm F1.8, 24-70mm F2.8 and 135mm F1.8 Art lenses

21 Feb

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_7013646430″,”galleryId”:”7013646430″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Sigma has released a trio of its high-end ‘Art’ lenses: two primes and one zoom. All three are designed for full-frame Canon, Nikon and Sigma bodies.

The first is the ultra-wide 14mm F1.8 DG HSM, which Sigma claims is the ‘world’s first and only F1.8 ultra-wide-angle lens.’  The lens has 16 elements, three of which are FLD (low dispersion) and four are SLD (super-low-dispersion). It also has a large (80mm) aspherical front element to reduce distortion and ‘deliver outstanding image quality from the center to the edges.’ The 14mm F1.8 has 9 rounded aperture blades, a minimum focus distance of 27cm/11in and a ring-type ultrasonic (HSM) focus motor.

Next up is the Sigma 24-70mm F2.8 DG OS HSM Art. This lens features three SLD and four aspherical, nine rounded aperture blades and optical image stabilization. The lens is weather-sealed and made of a combination of metal and ‘thermally stable composite’ material. The minimum focus distance of the 24-70 is 37cm/1.5in and it uses 82mm filters.

Last, but certainly not least, is the 135mm F1.8 DG HSM telephoto prime. Sigma says that this lens ‘offers the […] resolution required for 50MP or higher ultra-high-megapixel DSLRs.’ It has a hypersonic (ring-type ultrasonic) focus motor that delivers fast (and ‘exceptionally stable’) focus speeds, while an acceleration sensor ‘detects the orientation of the lens’ so the AF system can respond to ‘varying loads on the focusing group due to gravity.’

The lens has 9 rounded aperture blades, dust and splashproof construction, and a weight of 1130g/40.2oz.

Pricing and availability for all three lenses will be announced at a date to be determined.

SIGMA 14mm F1.8 DG HSM
Introducing the world’s first and only* F1.8 ultra-wide-angle lens

A true high-speed lens that delivers a new dimension of visual experience

*Among interchangeable lens for digital SLRs as of February 2017

  1. 14mm ultra-wide angle of view and F1.8 brightness deliver a new dimension of visual experience
  2. Seventh 35mm full-frame prime lens to join the Art line
  3. Other features 

A true high-speed lens that delivers a new dimension of visual experience

In taking photographs of starry skies or other celestial scenes at night, or of the seashore with a wide perspective, a large-diameter lens is a strong ally, since it allows the capture of a moving subject by adjusting shutter speed without relying on ISO sensitivity. With its full-frame 35mm coverage, 14mm focal length for an ultra-wide angle of view, F2 barrier-breaking F1.8, the SIGMA 14mm F1.8 DG HSM | Art is the true high-speed ultra-wide-angle lens for which so many photographers have been waiting. Although some zoom lenses are available that can cover 14mm, the large diameter delivering F1.8 brightness is a singular advantage. Going beyond fast shutter speed, this lens can capture a swarm of fireflies with crystal clarity, a beautiful bokeh effect, and outstanding control of light streaking.

?Key features?

  1. 14mm ultra-wide angle of view and F1.8 brightness deliver a new dimension of visual experience

By leveraging its extreme angle of view and the dramatic perspective this creates, an ultra-wide-angle lens can get up close and personal with a subject while at the same time taking in a vast background—an example of photography going beyond normal human vision.

SIGMA 14mm F1.8 DG HSM | Art combines the extremely deep depth of field that comes from an ultra-wide angle of view with the extremely shallow depth of field that comes from F1.8 brightness. The result is a sharply captured subject set against a vast background dramatically blurred with a beautiful bokeh effect. It is a highly impressive mode of photographic expression that until now simply has not existed.

  • Minimized chromatic aberrations

Three FLD (“F” Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help minimize transverse chromatic aberration, which tends to be noticeable in shots taken with ultra-wide-angle lenses. The result is outstanding image quality from the center of the image to the edges.

  • Featuring a large-diameter aspherical lens element

The SIGMA 12-24mmF4 DG HSM | Art was the first SIGMA lens to feature a large ?80mm aspherical lens element. Building on the expertise derived from this success, the new lens features a large ?80mm precision-molded glass aspherical lens as its front element. This technology has made possible the 14mm F1.8 specification—the first of its kind.

  • Minimized distortion

Serving as the front lens element, the large ?80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.

  • Distinctive bokeh effect

Even at the 14mm ultra-wide-angle of view, F1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a bokeh background. It’s the unique mode of expression that only a large-diameter lens can deliver. 

  1. Seventh 35mm full-frame prime lens to join the Art line

Launched in 2012, the SIGMA 35mm F1.4 DG HSM | Art was the first lens in the Art line. Since then, SIGMA has developed a wide variety of lenses for the line, and the SIGMA 14mm F1.8 DG HSM | Art is the seventh prime lens in the line to offer 35mm full-frame coverage. Now even stronger, the Art line sets the new standard for prime lenses in the ultra-high-megapixel era.

  1. Other features
  • Fast AF with full-time manual override

Note: The operation of full-time MF may vary based on mount type

  • Compatible with Mount Converter MC-11
  • Available SIGMA USB DOCK (Makes customization and flexible adjustment possible)
  • Available Mount Conversion Service (Allows use with another camera body)
  • Rounded diaphragm
  • Designed to minimize flare and ghosting
  • High-precision, durable brass bayonet mount
  • Evaluation with SIGMA’s own MTF measuring system “A1”
  • Made in Japan (With outstanding craftsmanship)
  • The lens barrel is engraved with the year of release

SIGMA 24-70mm F2.8 DG OS HSM
Top-level performance optimized for the era of ultra-high-megapixel cameras

  1. The large-diameter standard zoom ideal for today’s ultra-high-megapixel digital cameras
  2. OS functionality and newly designed HSM for success on any shoot
  3. Lens barrel designed for high rigidity
  4. Other features?

The definitive large-diameter standard zoom lens for any shoot

What photographers demand from the 24-70mm F2.8 specification is much more than outstanding image quality. They want all the features that make this a go-to lens for a wide range of photographic opportunities, including optical design ideal for the latest ultra-high-megapixel digital cameras, hypersonic motor (HSM) for high-speed autofocus, optical stabilizer (OS) with powerful stabilization effect, dust- and splash-proof mount with rubber sealing, and a metal barrel for a stable, rigid feel. This all-new 24-70mm F2.8 lens from SIGMA delivers the performance and functionality that help pros succeed in news, nature, and many other fields of photography.

?Key features?

  1. The large-diameter standard zoom ideal for today’s ultra-high-megapixel digital cameras 
  • Outstanding optical performance

Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements help minimize optical aberrations. To ensure outstanding image quality from the center to the edges of the photograph, the optical system minimizes coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control, The optical system also minimizes distortion, which can be particularly evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.

  • A 24-70mm F2.8 lens that meets the high standards of the Art line

SIGMA has continuously pioneered 24-70mm F2.8 lenses that are a step ahead of the times. The first model of this specification, SIGMA 24-70mm F2.8 EX DG ASPHERICAL DF, launched in 2001. Representing the fourth generation of the family, the new SIGMA 24-70mm F2.8 DG OS HSM | Art accomplishes a challenging feat in optical design: incorporating optical stabilizer functionality in a large-diameter standard zoom. By leveraging all of its design and manufacturing expertise, SIGMA has ensured that this new lens fulfills the uncompromising requirements of the Art line for image and build quality.

  • Bokeh that is a cut above

At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are often used at wide-open aperture, SIGMA has paid close attention to the shape of the bokeh, aiming for perfect circularity. 

  • Incorporating advanced aspherical lens processing technology

Aspherical lenses necessitate refined expertise in the design and manufacturing of advanced, high-performance lenses. SIGMA’s first products to feature this technology were the SIGMA 12-24mm F4 DG HSM | Art and SIGMA 14mm F1.8 DG HSM | Art, which both incorporated a large ?80mm aspherical lens as their front lens element. Building on the success of these predecessors, the SIGMA 24-70mm F2.8 DG HSM | Art incorporates an aspherical lens element that helps achieve extremely high resolution. This element is much thicker at the center than the edges, and forming its unusual shape is a feat of manufacturing technology. Moreover, SIGMA processes the surface of this aspherical lens element with ultra-precise tolerances that are measured in hundredths of a micrometer. This extremely fine surface allows the SIGMA 24-70mm F2.8 DG HSM | Art to deliver a very natural and smooth bokeh effect, without the visible concentric rings that afflict typical aspherical lens elements.

  1. OS functionality and newly designed HSM for success on any shoot

Designed for advanced utility in a wide variety of situations, the optical stabilizer (OS) offers a powerful stabilization effect. The newly designed large hypersonic motor (HSM) offers 1.3 times the torque of its predecessor and exceptionally stable performance even at lower speeds.

* Based on CIPA’s guideline. Measuring at telephoto end, when it is attached to the camera with 35mm image sensor.

  1. Lens barrel designed for high rigidity

Since large-diameter standard zoom lenses tend to serve as a go-to lens and see frequent use, the SIGMA 24-70mm F2.8 DG HSM | Art is designed to stand up to the challenging shooting environments that pros encounter. To this end, the lens barrel contains a large amount of metal, while the external moving parts feature thermally stable composite (TSC), which is resistant to thermal expansion and contraction. This structure contributes not only to the outstanding optical performance of the lens but also to its high rigidity and confidence-inspiring build quality.

  1. Other features
  • Mount with dust- and splash-proof design

Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing helps provide peace of mind. In addition, the front lens element features a water- and oil-repellent coating that helps the lens perform well in the rain, near water, and in other challenging conditions.

  • Nikon electromagnetic diaphragm mechanism included

The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.

Note: Functionality may be limited on some camera bodies.

  • Fast AF with full-time manual focus
  • Compatible with Mount Converter MC-11
  • Available SIGMA USB DOCK (Makes customization and flexible adjustment possible)

Introducing the ultimate 135mm telephoto featuring top-level performance

135mm telephoto lenses are often categorized as the foundational telephoto, the first one to add to a lens collection. This focal length delivers a strong perspective compression effect, while the large diameter with F1.8 brightness provides a dramatic bokeh effect. By minimizing axial chromatic aberration, the SIGMA 135mm F1.8 DG HSM | Art makes this bokeh effect not only impressive but also beautiful while delivering superb contrast and sharp image quality in every shot. It offers the outstanding resolution required for 50MP or higher ultra-high-megapixel DSLRs. By incorporating its latest innovations in design and optical glass and rethinking every aspect of the lens, SIGMA has ensured outstanding image quality all the way to the edges, establishing the new standard in 135mm telephoto lenses.

With resolution so crystal-clear that individual hairs can be discerned in a portrait, this large-diameter lens also delivers a beautiful bokeh effect, giving photographers everything they need. It is ideal for close-ups and full-body shots, with subjects standing out against a pleasantly blurred background. In addition to standard portraits, including bridal shots, this lens is a top performer for live events, with its super-fast autofocus capturing subjects with ease.

?Key features?

  1. The ultimate 135mm telephoto designed to prioritize optical performance
  • Image quality optimal for ultra-high-megapixel DSLRs

To deliver the ultra-high resolution that brings the best out of 50MP or higher ultra-high-megapixel DSLRs, the focus mechanism features SIGMA’s floating system. No matter what the distance from the subject, this lens offers top performance from the center to the edges of the image. By minimizing distortion as well, the lens delivers impeccable image quality—no need for digital adjustment during image processing.

  • Ideal for portraits requiring a dramatic bokeh effect

The 135mm focal length delivers a stunning compression effect: even fairly close to the subject, the telephoto ring allows the photographer to establish a variety of dramatic perspectives. The compression effect truly shines in both close-ups and full-length portraits, making composition easy. Moreover, the large diameter with F1.8 brightness makes possible a body shot with an impressive bokeh background. In sum, this lens puts a full menu of compositional options at the photographer’s fingertips.

  1. Fast and nimble autofocus photography

The large hypersonic motor (HSM) offers two benefits. It delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. The acceleration sensor detects the orientation of the lens, allowing the autofocus system to respond to varying loads on the focusing group due to gravity. Along with the optimized AF algorithm, these features deliver fast autofocus photography. In addition, the focus limiter makes AF highly responsive to distance from the subject for even more nimble performance.

  1. Sixth 35mm full-frame prime lens to join the Art line

Launched in 2012, the SIGMA 35mm F1.4 DG HSM | Art was the first lens in the Art line. Since then, SIGMA has developed a wide variety of lenses for the line, and the SIGMA 135mm F1.8 DG HSM?Art is the sixth prime lens in the line to offer 35mm full-frame coverage. Now even stronger, the Art line sets the new standard for prime lenses in the ultra-high-megapixel era.

Master of one: Mitakon Speedmaster 135mm F1.4 pre-production sample gallery

09 Dec

You might remember us getting our hands on the Mitakon Speedmaster 135mm F1.4 at the Photo Plus Expo back in October. We handled the lens and wrote up some quick impressions at the show, but we were lucky enough to be given one of the prototype lenses to take home to Seattle with us.

Our sample is an engineering prototype of the E-mount version of this beastly lens, and we’ve spent the past few weeks gathering samples both in our studio and out and about around Seattle, to give you an idea of what it can do. 

The 135mm F1.4 is a massive piece of glass, and in its E-mount flavor, absolutely dwarfs Sony’s a7 bodies. With a 105mm thread, fully manual operation and a weight of over six pounds (about 2.7kg), it can be rather intimidating, and is near impossible to use hand-held. With the proper support in place though it isn’t difficult to use at all, and can reward patient use with dramatic, unique results.

When viewing our samples, it’s worth bearing a couple of things in mind. Firstly, this lens is one-of-a-kind. Almost literally. So it has no direct competitors that we can shoot alongside. Also note what we said earlier – we were using an engineering prototype that was not cosmetically final, and may not be completely representative, optically, of the finished shipping lenses when they become available (although it’s likely to at least be extremely close)

With that in mind, take a look, and enjoy with us this truly unique hunk of metal and glass. Let us know what you think in the comments!
