Sony FE 85mm f/1.4 GM Lens REVIEW vs Sigma 85mm ART

For the past three weeks I have been shooting with the Sony FE 85mm f/1.4 GM Lens.  In this review I compare it to the Sigma 85mm ART which I also recent reviewed vs the Canon 85mm f/1.2L Lens.https://youtu.be/ebqeszg5mdwThe Sony 85mm f/1.4 GM lens is a $1,798.00 f/1.4 to f/16 lens with an 11-blade aperture design The Sigma 85mm f/1.4 ART is a $1,199.00 f/1.4 to f/16 lens with a 9-blade aperture design AND you need the MC-11 Adapter because they do not make it in FE mount which brings the total cost to $1448 though Sigma sells bundles that might bring the price down to $1400Support our work - buy via our links

Build Quality:

Both of these lenses are exceptionally well made though the Sony gives you aperture control on the ring with a click/de click switch along with a focus hold button that can be assigned eye-af as well as several other options. The Sony len is dust and moisture resistant and significantly lighter at 1.80 lb (820 g) with a front filter size of 77mm. The Sigma weighs 2.49 lbs not including the extra weight of the adapter and the front filter is a massive 86mm. Another lens you should consider in this focal range is the Zeiss Batis 85mm f/1.8 which weighs just 1 lbs and is noticeably smaller too - I have not personally tested this lens so cannot comment on how it compares but based on the reviews I have seen it too offers a sharp lens and costs less at $1199 no adapter needed. The Sony can be a little noisy to focus at times I don’t hear the same from the Sigma.

Focus:

I expected the native sony lens to blow away the Sigma using the adapter and while the Sony certainly is faster and offers all the additional AF modes like tracking and eye af it really isn’t a fast focusing lens and even with the adapter the sigma does quite well though it starts to slow and hesitate noticeably when you move the AF point near the edges.

Image quality:

After spending a few days shooting and comparing images I can say that I have an extremely hard time deciding if one lens is sharper - wide open at f/1.4 I find both to be exceptionally and sharp. The 11 bladed aperture might contribute to slightly smoother bokeh but the difference is slight. In some lighting scenarios the sigma produces a slightly warmer image. Overall though from center to edge from wide open to f/16 these are two fine lenses.

Summary:

While I’d like to save you a couple hundred I would recommend the Sony 85 for most users - it’s smaller/lighter, offers weather sealing and a few bells and whistles that make it a more versatile lens. The Sigma though is a fantastic value if you don’t mind bigger/heavier and the clunk of using the MC11 adapter. And finally I briefly mentioned it the Zeis batis 85mm f/1.8 which isn’t as fast but much smaller, lighter though it’s almost the same price as the Sigma.Support our work - buy via our links

New Lenses from Sigma 100-400, 14mm f/1.8, 24-70 f/2.8, 135mm f/1.8

Sigma has JUST ANNOUNCED four new ART series lenses.  I am a huge fan of the ART series, see my recent 85mm ART review - these have been incredibly sharp lenses that offer excellent value and the four newly announced lenses really round out their collection. We do not have pricing information or confirmed availability yet though my contact at Sigma states late April, early May. Press Release info below (my thoughts in bold along with my guess on cost - this page will be updated as new information become available.

Which lens in the lineup are you most excited about?

 

The Sigma 100-400mm 5-6.3 DG HSM OS Contemporary

Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary LensThe Sigma 100-400mm 5-6.3 DG HSM OS Contemporary is a state-of-the-art telephoto zoom that brings a new level of portability and quality to the super telephoto market. Touting Sigma’s Optical Stabilizer (OS), the Sigma 100-400mm 5-6.3 Contemporary is highly compact and lightweight compared to similar products on this market. A push/pull zooming function and a new Hyper Sonic Motor (HSM) allow for a more responsive approach to photography while a 1:3.8 macro feature can be utilized from up close or from a further distance.Physical Specs -Weight 2.56 lb (1160 g)Diameter 86 mm (3.4″)Length 182 mm (7.18″)Sealing Yesfor comparison the new Canon 70-300 weighs 1.56 lb (708 g) and costs $550 and the Canon 100-400 MK II weighs  3.5 lb  (1.59 kg) and costs $2000I expect this lens to be nearly as sharp as Canon's 100-400 Mark II which costs almost double the price.  It does include weather sealing though I suspect it isn't at the same level as Canon's 100-400 Mark II and I notice an absence of a tripod color - something often desired in a longer lens as a way to give you a stable mounting point when using smaller cameras.  I am confused by the push/pull designation - this lens looks like a typical rotate to zoom - maybe you can also push/pull but there isn't much to grab onto.  Guess- around $1200  

The Sigma 24-70mm 2.8 DG HSM OS Art

The Sigma 24-70mm 2.8 DG HSM OS ArtThe Sigma 24-70mm 2.8 DG HSM OS Art is a premium workhorse zoom lens designed for the latest high megapixel DSLRs. A constant aperture of 2.8 through the zoom range make this a highly versatile tool and a brand new Optical Stabilization (OS) system help compensate for camera shake. Though a common focal length, the Sigma 24-70mm Art brings a new level of usability and durability featuring a rugged metal barrel and an emphasis on image quality. Building off the experience from the 12-24mm Art, the aspherical elements used in the 24-70mm 2.8 OS Art undergo a highly precise level of polishing producing elements thicker in the center then on the edges. This process creates stunning image quality and beautiful circular bokeh.Canon does not have a stabilized 24-70 f/2.8 and I suspect this new ART lens will be as sharp as Canon's current 24-70 f/2.8 L and it offers stabilization and it will likely be cheaper.   Downsides? I don't see any right now as long as this lens is up to the standard of Sigma's existing ART series line. It even has a slightly smaller front filter size 80mm vs 82mm in the Canon.   On price I suspect somewhere around $1400 slightly more expensive than the Tamron version. I expect this ART to be much better than the Tamron. 

The Sigma 135mm 1.8 DG HSM Art

The Sigma 135mm 1.8 DG HSM ArtThe Sigma 135mm 1.8 DG HSM Art is a medium telephoto prime lens designed for modern high megapixel DSLRs. A new large Hyper Sonic Motor produces significant torque to the focusing group for better speed while the acceleration sensor detects the position of the lens and compensates for such factors as gravity to help aid in focusing performance. This state-of-the-art prime lens touts a dust and splash proof construction for guaranteed performance in any condition and its large 1.8 Fstop allows for more creative control over imagery. A stunning compression effect make the Sigma 135m 1.8 Art the ideal portrait lens while its large aperture help with event photography and much more.This seems very similar in size and weight to the 85mm that I have recently tested and found to be excellent.  At 135mm you can get some incredible background separation from your subject. I will be interested to see how this compares to Nikon AF-S NIKKOR 105mm f/1.4E lens that is a little lighter and smaller but at $2100.00 likely a good bit more expensive. For wedding work I love primes at 85mm and below - above that and you may find yourself needing to move more than you want or are easily able to do in some situations BUT for portrait photographers these longer primes can offer stunningly beautiful shots.  Price Guess $1200

The Sigma 14mm 1.8 DG HSM Art

Sigma 14mm f/1.8 DG HSM Art Lens for Canon EFThe Sigma 14mm 1.8 DG HSM Art is the world's first 1.8 prime lens at the 14mm focal length. This fast wide prime features the same large aspherical element touted in the Sigma 12-24mm F4 Art to control distortion and create stunning imagery. An updated Hyper Sonic Motor (HSM) provides fast and accurate autofocus while 3 Premium FLD and 4 SLD glass elements control chromatic aberration and sagittal comma flare. Building on the highly reputable Art line, the Sigma 14mm 1.8 DG HSM Art is designed to resolve the latest high megapixel DSLR sensors.This lens is an astrophotographers dream! That is of course hoping it is at the level of their other ART series lenses and minimizes distortion. To have a full frame lens as fast as f/1.8 gives you some awesome flexibility when shooting the night sky.  Also useful for low light receptions and documentary work. Guess - $1100.00   

Sigma Adds Full-Frame 20mm f/1.4 Lens to Art Series

Sigma 20mm f/1.4Sigma's excellent ART series lenses come in a 24mm f/1.4, 35mm f/1.4 and the 50mm f/1.4 focal lengths, and now, if you felt like 24 wasn't quite wide enough, you are in luck- Sigma has just released the 20mm f/1.4.  This is the first 20mm f/1.4 lens designed for full-frame cameras. This wider focal length is well-suited to landscapes, astrophotography, event shooting, and low-light work.What I can't figure out though - The difference between 20mm and 24mm focal length is slight, very slight. Was there such demand for a wider version of the 24mm that Sigma felt compelled to make this? I am sure it will be a sharp lens as ALL the other Sigma Art lenses are. We own the 35 and 50 and love them. I review the 24mm f/1.4 and found it to be excellent.  I am just surprised that the next ART lens Sigma released is so close to an existing lens.  What I am really saying here is "I WANT THE SIGMA ART 85MM!!!" and I am not excited about other Sigma lenses until I get what I want! Maybe a 135mm f2, that might get me excited.  How about you - what Sigma ART series lens would you like to see next?The 20mm f/1.4 DG HSM Art lens will be available in Canon EF, Nikon F, and Sigma SA mounts for $899Buy from B&H Photo or Amazon (support my work by using those links to preorder) \ Available Mid NovemberSigma Press ReleaseTruly wide and truly fast, the Canon EF mount 20mm f/1.4 DG HSM Lens is a member of the venerable Art series of Global Vision lenses from Sigma and pairs a sophisticated optical design with a robust physical construction. Comprised of 15 elements in 11 groups, the lens design includes both “F” Low Dispersion (FLD) and Special Low Dispersion (SLD) glass to significantly reduce chromatic and spherical aberrations, as well as limit distortion for clean, sharp, and evenly illuminated imagery. A Super Multi-Layer Coating has also been applied to minimize surface reflections, flare, and ghosting for increased contrast and color accuracy. The wide focal length and consistent image quality make this lens especially suitable for landscape, interior, architectural, and astrophotography applications, while the fast f/1.4 maximum aperture deems it ideal for natural and low-light shooting.Complementing the optical performance is an equally adept Hyper Sonic Motor, which provides fast, smooth, and near-silent autofocus performance. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control and focusing as close as 10.9″. The lens barrel is constructed using a Thermally Stable Composite material, which supports working in a wide variety of temperatures and conditions, and the lens mount is constructed from brass for long-term durability and mounting accuracy. Additionally, this lens is also compatible with the optional Sigma USB Dock for fine-tuned control over focusing parameters and other lens characteristics.

New Sigma ART series lens 24-35mm F/2

Update #2 (7/20/15): Price at $999 - Preorder now from B&H Canon Mount | Nikon Mount | Sigma MountUpdate: The lens is now official - Expected arrival at the end of July. No word on price - I suspect it will be under $1000.  My comment about the 18-35 ART lens - "it's like carrying around a bag of primes" also applies to this lens and Sigma has actually said something similar "It covers three of the most commonly used prime lenses, 24mm, 28mm and 35mm all in one lens. "- I think they watched my video ;)Listings are now live on B&H Photo but incredibly thin on details we care about - Price and a firm ship date.Will you be ordering?Sigma 24-35 f/2 Canon Mount | Nikon Mount | Sigma MountBased on comments you left on the Facebook post - interest is mixed, many of you feel similar to me, the range here is just short enough to be a little less exciting- though the sharpness and the fact that you get f/2 will be lovely.Original Post:We are a huge fan of the ART series lenses. Every lens I have tried has been exceptionally sharp with top-notch build quality. See what's in our bag for the Sigma lenses we use daily.The next lens Sigma will be announcing is the 24-35 f/2 and to be honest this has me scratching my head.   Sure f/2 in a zoom lens is quite amazing, similar to the amazing Sigma 18-35 f/1.8 for crop sensors but that range is awfully short.Are you interested? How would you use?  I would be more interested if they could get the range closer to 50, so a 24-50 f/2 would be sweet but ending at 35mm feels a bit limiting.sigma 24-35 f/2 ART series sigma 24-35 f/2 ART seriesPhotos courtesy of digicame-info.comThanks Knut Aage Dahl for alerting me to the info.Full Press Release from SigmaThe Sigma Corporation is pleased to announce that we are going to introduce the SIGMA 24-35mm F2 DG HSM | Art, the world's first*1 large-aperture full-frame wide-angle zoom lens offering F2 brightness throughout the zoom range.While offering the premier optics of the Art line, this lens covers 24mm, 28mm and 35mm focal lengths. Incredible performance overturns the conventional perception of a zoom lens.SIGMA was determined to create a zoom lens that offers the same brightness and resolution as a fixed focal length lens: in other words, the highest level of optical performance. The result of this challenge was the SIGMA 18-35mm F1.8 DC HSM | Art, the world’s first zoom to offer a fast F1.8 aperture value throughout the zoom range. Building on this concept, SIGMA has developed the new SIGMA 24-35mm F2 DG HSM | Art for 35mm full frame sensor. It allows photographers to carry one lens to do the work of three fixed focal length lenses, a 24mm, 28mm and 35mm — with F2 brightness and top optical performance. One package delivers flexible functionality and high convenience. In particular, at the 24mm and 35mm focal lengths, this lens offers the performance that is equivalent to that of two prime lenses in the Art line. Instead of changing one high-performance fixed focal length lens for another, simply zoom. This is a new zoom lens for 35mm full frame sensor SLRs that offers the quality of a fixed focal length lens at various angles of view.Key features1. The world’s first large-aperture full-frame zoom lens offering a wide open aperture of F2 throughout the zoom rangeA large-diameter zoom lens covering the full frame image sensor. Optical performance equivalent to a fixed focal length lens throughout the entire zoom range. These are the concepts the SIGMA 24-35mm F2 DG HSM embodies. It covers three of the most commonly used prime lenses, 24mm, 28mm and 35mm all in one lens. In order to achieve an attractive bokeh effect at wide aperture, we have developed the world's first zoom lens for the 35mm full frame sensor with an F2 aperture value throughout the zoom range*1.2. Outstanding optical performance of the fixed focal length lenses in SIGMA’s Art lineThe SIGMA 24-35mm F2 DG HSM builds on the concept of the SIGMA 18-35mm F1.8 DC HSM | Art, the world’s first zoom lens to offer F1.8 brightness throughout the zoom range. Thanks to the outstanding optical performance, the lens provides the quality of high performance fixed focal length lenses in the Art line.3. Covering the range of three fixed focal length wide-angle lensesDelivering excellent functionality and convenience, one lens offers the equivalent quality of three high-performance fixed focal length lenses at F2 brightness: 24mm, 28mm and 35mm. With a minimum focusing distance of 28cm and a maximum magnification ratio of 1:4.4, this lens is suitable for close-up shooting, portraits with an attractive bokeh and deep-focus landscape photography. Photographers have access to the angle of view equivalent to that of three wide-angle lenses without having to switch them. While achieving the desired background effect can be difficult with a conventional wide-angle lens, the large diameter of this lens allows photographers to open the aperture wide and use the shallow focus to achieve stunning results.4. Incorporating SIGMA’s latest technologiesTo realize a large-diameter zoom lens for full frame cameras with F2 brightness, SIGMA designed each and every part with uncompromising care and quality. The lens incorporates large-diameter aspherical lens elements, which require advanced technologies to manufacture, one FLD (“F” Low Dispersion)*2 glass and seven SLD (Special Low Dispersion) glass elements, of which two are aspherical lenses. The advanced optics and optimized lens power distribution minimize spherical aberration, axial chromatic aberration and field curvature, resulting in outstanding optical performance. Even at widest aperture, this lens delivers breathtaking image quality.5. Convenient handlingThe inner focusing system eliminates front lens rotation, enhancing the lens' stability and allowing use of Circular Polarizing filters. This specification is particularly convenient for shooting video.Other featuresMinimum focusing distance of 28cmWith a minimum focusing distance of 28cm and a maximum magnification ratio of 1:4.4, this lens is excellent for close-up photography.Designed to minimize flare and ghostingFrom an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.Hyper Sonic Motor ensures High AF SpeedThe HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. By optimizing the AF algorithm, smoother AF is achieved. Also, this lens offers full-time MF by rotating the focus ring of the lens while auto focusing*3. Without changing the AF/MF Focus Mode Switch, it allows faster focus adjustment.Rounded DiaphragmThe 9 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.Brass bayonet mountThis lens incorporates a brass bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.Applicable for the Mount Conversion ServiceAs an experienced lens manufacturer that has been creating a diverse range of interchangeable lenses, we have started the innovative "Mount Conversion Service*4".
