Sigma announces all-new 50mm F1.4 DG HSM 'Art' lens

By dpreview staff on Jan 6, 2014 at 22:00 GMT

CES 2014: Sigma has announced the 50mm F1.4 DG HSM | A, a fast 'normal' prime for full frame DSLRs. It will also work on APS-C / DX format cameras, offering a 75mm equivalent short telephoto effect.

It's a completely new lens, rather than a revision of Sigma's existing 50mm F1.4 EX DG HSM, with an unusually complex optical formula for its type (13 elements in 8 groups). It's also rather large, with a strong family resemblance to the excellent 35mm F1.4 DG HSM. Overall this suggests Sigma has adapted an optical design normally used for retrofocal wide angle primes (rather like Zeiss has with the Otus 1.4/55), instead of producing a variant on the double-Gauss formula generally used for 50mm primes. The 50mm F1.4 will be available in Canon, Nikon, Sigma and Sony mounts.   

The lens employs an ultrasonic-type focusing motor, and according to Sigma uses improved autofocus algorithms. It's also compatible with Sigma's USB dock (allowing the user to update the firmware when required), and Sigma's Mount Conversion service. Pricing and availability are still to be confirmed.

Press Release:

A | Art Sigma 50mm F1.4 DG HSM 

In 2008, Sigma released a large diameter standard lens designed for digital SLRs, "SIGMA 50mm F1.4 EX DG HSM". At that time, products for film cameras were prevalent, yet we spent enormous effort to set a new benchmark for the 50mm lens that optimizes the characteristics of digital cameras, such as compensating peripheral brightness, controlling the point images in the corners, and improving the image drawing, not only around the focusing point, but also other areas in the image.

In recent years, as the DSLR evolves, development of image sensors for higher pixel size has created the photographers’ desire for the lenses with superior performance. In 2012, Sigma has announced the "Art" line that achieves unsurpassed expressive performance to fulfill the higher requirement of photographers. The first lens from the "Art" line "SIGMA 35mm F1.4 DG HSM [A 012]" sought for uncompromising performance, and it resulted in great reviews as well as a lot of awards from all over the world. Based on the accumulated wisdom and know-how to establish the standard for our "Art" line series, we are proud to announce the development of the new high performance standard lens with a large diameter for this new era of superb image quality.

  • Corresponding AF Mounts: SIGMA, Canon, Sony and Nikon 
  • Accessory: Case, Petal-Type Hood (LH830-02) supplied.

* The Appearance and specifications are subject to change without notice.

Special Features

1. Art line delivers high-level artistic expression

SIGMA is organizing all its interchangeable lenses into three product lines; Contemporary, Art, and Sports, where each line has a distinctive concept. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. With the astonishing rendering performance that meets the high standard, along with landscapes, portraits still-life, close-up, and casual snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture and starry skies and many other scenes.

2. Astonishing rendering performance

Utilizing know-how and the latest design technology accumulated through the past developments, it corrects the aberration thoroughly and achieves high resolution and astonishing rendering performance even near the edge of the image.

  Achieving both high resolution and beautiful bokeh

While pursuing a high level of resolution on the focused point, bokeh in front and behind the point of focus is carefully maintained to have soft rendering. Aberrations including sagittal coma flare and color distortion that affect the image quality are thoroughly corrected. From open aperture, high-definition rendering without blur is achieved. Moreover, by ensuring vignetting at the minimum and preventing color blur around the front and back of the focus point, it also achieves natural bokeh.

Excellent correction of sagittal coma flare

It is ideal for a wide aperture standard lens to have a high rendering performance from open aperture throughout the entire image. For instance, the molded glass aspherical lens elements provide excellent correction to sagittal coma flare. It is perfect for astronomical photography and shooting of illumination because of the reduced blur on the point light sources near the edge of the image. It also creates an attractive bokeh in portraits and indoor shooting.

• Correction of axial chromatic aberration

For axial chromatic aberration that is hard to correct even during the image processing, SLD (Special Low Dispersion) glass elements are incorporated, ensuring high image quality throughout the entire focusing range. The lens achieves sharp and high contrast image rendering.

• Minimized distortion

It is not possible to compensate for distortion just by changing the aperture values. Thus, the lens development stage was vital in ensuring minimized distortion. The "SIGMA 50mm F1.4 DG HSM" has positioned each glass element to optimize the power layout at respective positions, and succeeded in minimizing distortion.

• Rich peripheral brightness

It secures very rich brightness in the peripheral areas, which can be a common problem for a lens with a large diameter. By positioning wide elements in the front group, it has improved the efficiency at large apertures. Since it is capable of minimizing vignetting, very clear depiction across the image is ensured.

• Designed to minimize flare and ghosting

Flare and ghosting were thoroughly measured and monitored from the lens development stage to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.

• Minimum focusing distance of 40cm

The lens incorporates a floating system that adjusts the distance between lens groups while focusing, thereby reducing the amount of lens movement required. This achieves a minimum focusing distance of 40cm and maximum magnification ratio of 1:5.6. As there is less variation in aberration at different shooting distances, the lens delivers high rendering performance throughout the entire focusing range.

3. Hyper Sonic Motor ensures High AF Speed

The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. Optimizing AF algorithm, smoother AF is achieved. It also enables full-time manual focusing capability which allows sensible focus adjustment by simply rotating the focus ring.

4. New Customizing Option added to “SIGMA USB DOCK”

With the optional SIGMA USB DOCK and the dedicated special software “SIGMA Optimization Pro”, you can update your lens firmware, or adjust focus points by attaching this lens to a SIGMA USB DOCK connected to a computer.

Other Features

Incorporating Rounded Diaphragm

The 9 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.

Design Concept

With the new product lines, supplied hoods incorporate rubber for the connected part. Lens caps and AF/MF switches are also newly designed in order to improve usability. For the parts inside, metals and a new material called TSC (Thermally Stable Composite), which works well with metals, are located to achieve products with high accuracy. The lens barrel includes the year of release, engraved for users to recognize when the lens was released.

Brass made bayonet mount

This lens incorporates a brass made 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.

Evaluation with Sigma’s own MTF measuring system “A1”

We used to measure lens performance with MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA 50mm F1.4 DG FISM will all be checked using this “A1” before they are shipped.

*A1: Aizu1

“Made in Japan”

All Sigma's manufacturing - right down to molds and parts - is carried out under an integrated production system, entirely in Japan. We are now one of the very few manufacturers whose products are solely "made in Japan". We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of Sigma products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world, because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.

Applicable for the Mount Conversion Service

As an experienced lens manufacturer that has been creating a diverse range of interchangeable lenses, we have started the innovative chargeable service “Mount Conversion Service”. With this service, the mount of your current SIGMA lenses can be changed to another mount of your choice. It gives a new life to your favorite lenses when you wish to use it on a different camera body.

* This “Mount Conversion Service” is different from a normal repair. In order to apply for the service, please contact your nearest authorized subsidiary / distributor of SIGMA.

I wasn't expecting to buy a new 50, especially after getting the CV Nokton f/1.1 for my Leica M3. However, the 35mm f/1.4 Art lens from Sigma is among the best pieces of glass I've ever used. If this 50 performs similarly, my "nifty fifty" Canon is going to be retired. I can't wait to see some sample photos!

£3k for a DSLR lens is pushing the envelope of acceptability in my book. I don't think Zeiss expect to sell many. If the Sigma 50mm 1.4 Art lens is even 90% of the Otus at a price that most are expecting it should be on everyone's list.

I can't wait to hear how it performs, I am hoping it's super sharp with amazing contrast, and it gives the Otus a run for it's money, I am also hoping that the price is similar to the old Sigma 50 witch I own, they should advertise it as the Canon L killer because i'm sure it will be better than the 50 L witch is over priced and under performs, The Canon 50 1.4 is nice just because of it's small size and weight, I wish Sony could make a 50 1.4 the same size for there A7/A7r, I also want to see a new Sigma 24/70 f2.8 IS, or f2, the only thing I wish is that Sigma was making there new lenses weather sealed, that is the only place that Canon has an edge, but image quality is first priority, I love my Sigma 35 f1.4 Art lens, and I also love my Sigma 85 f1.4 that I bought for 1/3 the price of the Canon 85 L, and for me it wasn't about the money, I would of bought the Canon if I thought it was better, but I couldn't deal with the slow focusing, anyway, go Sigma, and lookout Canon and Nikon

Sorry but this is just absolutely false. I take my Pentax's into the rain all the time. HEAVY rain (and snow, sleet, mud, etc.). Will the images win awards for sharpness/clarity? No, of course not. But they are still taken, without any damage to the equipment, and time after time after time it has proven to not be impossible.

And I have photographed in dust storms as well while in Afghanistan. You really don't know what you are talking about.

The current Sigma 50 mm f/1.4 is so good, especially the bokeh.

I'm only comparing it to the 50 mm f/1.4 lenses from Nikon and Canon. The Canon is the worst of the bunch, while the Nikon is good, but doesn't produce photos as pleasing as the Sigma.

I don't think I'd go for this "upgrade". The old one was also a fantastic size. I don't like this new lens due to its width.

I suppose if the results are incredible, it won't matter, but I had no issues with the current version.

It will be enough that this lens gets as good as their old 50mm f1.4 (+USB dock compatibility and closer focus distance) and it will be world's best 50mm autofocus lens. Just like the previous one was. I removed my beloved Canon 50mm f1.4 from my bag as soon as I bought the old sigma 50mm, and I understood that I didn't know what is a good 50mm lenst before I got it. I will chose this thing over the already-famous overpriced and overrated Otus in an instant... life is too short to miss the moments while rolling a focus ring... really... Zeiss, hearing this? Anyone?

The digital FF isn't going away anytime soon. Technological progress is making FF sensor manufacturing cheaper and faster. It won't die till there is a better solution. Actually, FF may be the reason for APSC and m4/3 formats sinking into oblivion, which would make a lot more sense.

I'm not talking about sensor size though APS-C looks like the best format at the moment.

I said SLR, or the mirror box should go and Canon has developed their lethal injection for the execution, the dual-pixel AF. though they won't kill the horse when 35mm format SLR is still by far the best in performance, user cost performance, and maker profit.

Do you realize that 35mm format means the 35mm film width (not the frame) for a vintage camera? 35mm as a dimension has nothing to do with a Digital SLR (DSLR) sensor.
However, I kinda agree with you. I think that EVF will dominate the market at some point, and I'd like them to improve that technology.

MTF graphs of the new lens show a lot of astigmatism compared to the older lens but higher resolution. The Bokeh will, most likely, be nervous where trees and shrubs are in the frame.

I was thinking of selling my current Sigma 50 as a preemptive measure but will hang on to it for now.

The MTF scores are also a tad lower than the Otus and so it will be an interesting time when comparison tests start to show up.

I've noticed on the sigma website, the weight has gone from 470g to 'TBD'. I thought 470g was too light for a lens of this size.

What I dont lie here, is that optical superiority always seems to come at the cost of a huge increase in size and/or weight. The Sigma 24-105 is also quie a bit bigger and heavier than the canon 24-105, which I find already at the borderline.

This is btw not only an issue with ISgma. Canons recent 35mm f/2 is alot bigger than the previous version.

Not the other way around. So far they released yet another high quality 50mm lens. Nothing to be excited about, at least: not till we see tests and pricing policy.
If it's as good, or better, as new Nikon - than we might consider getting excited.

@davidgp...I am thinking in the $800-$900 range...that would fall in line with the pricing of their other "Art" Lens offerings and slay the competition...Sigma does not need to go head-to-head with the Zeiss Opus as it is a different, exotic animal....

I can't wait for this lens, I have a 5Dlll, and I already own the Sigma 35 f1.4 art lens, and I love it, and I also own the Sigma 50 and 85 f1.4, and I also love them, but the 85 I had to try three of them at different stores before I found the sweet one that I bought, and the 50 I sent back to Sigma for an adjustment and now it is real nice, but I have still been hoping for this new Sigma 50 f1.4 art lens, and have really high hopes for it's image quality, and i think Sigma has gotten way better with there quality control now, I would love it if Sigma advertised it as the L killer, because I would bet anything that it will have better image quality than the over priced Canon 50 f1.2 L lens, and it will probably be very close to the image quality of the manual focus Zeiss Otus, and personally I wouldn't buy a manual focus only lens, Now I am hoping for a Sigma 135 f1.8 art, and a 24/70 that is less than f2.8 with IS or a 2.8 lens with a longer focal distance, like a 24/105 f2.8 IS

I have no doubt that this will indeed be an L killer but it's extremely bad advertising to make such a statement as you're automatically setting yourself up as the inferior brand. This is the opposite of what Sigma are trying to achieve with their new art line.

I am betting it will on Canon. The Sigma 35mm art outresolved the sensor there. The 29mpix score of the otus on the D800 will be out of reach.

But what do you expect at less then a quarter of the price with auto focus.

davidgp
By davidgp (3 months ago)

I'm not sure your logic works... according to your thinking (price of 35mm vs. 50mm) then the Otus would not cost $4K.

As I understand the announcement, Sigma is looking to create a lens that competes with the Otus, not the Canon 50f1.4.

Also, given Sigma's great success as of late, if they did produce a lens that is at least comparable to the Otus, then I'd guess the price would be somewhat above $1000,maybe $1200-1500.

No. But the fact that Sigma is being discussed as seriously comparable to "name brand" lenses and not just a way to save some money, shows how far they have come.

Something you won't have to do with the Zeiss is try 2 or 3 and pick the one that's best.

DANG. I knew they'd make this lens. I have the 35/1.4 and it is absolutely STELLAR. I bought the 35mm Art at the same time as I bought a Canon 50/1.2L (it was time for an upgrade) *except* that the $1200 Canon 50/1.2 was **worse** than my Canon 50/1.4. And by a long shot worse on color fringing, blooming, and flaring. Oh, and focus. So I sent it back. The Sigma? RAZOR sharp even wide open. But be ready for a DOF measured in mm when you get close. There is no Canon L I own that is as sharp wide open as the Sigma 35mm Art. Bravo! ... and where do I pre-order????

50 f/1.2 is a speciality lens, not build for maximum sharpness or corrections of aberrations. I have no clue how could you spend 1200$ without knowing what you pay for. Too much money out there?

Hahaha, "specialty lens". Sounds like you're trying to make up excuses for Canon.

When you spend a lot of money on a lens, you want something that's better than the cheaper versions. The 50 mm f/1.2 is worse in almost every way, and that extra aperture size isn't going to change a thing regarding the final result --- the photos --- which is the only thing that matters.

The lens it's replacing -- which Sigma released all the way back in March 2008 -- also to rave reviews, also had a 77mm filter size and was 35 grams heavier at 505 grams. It had five fewer elements, at 9, total, however, and at the time, DPReview's major criticism of the lens was that it was "overpriced" vs. the OEM lenses at Sigma's $499 MSRP.

My how things change. The OEMs (at least mine), have more than doubled their prices (in my case, on the SAME lens, plus a new one that's even much pricier), but Sigma comes out with "blow-your-doors-off-quality" "Art" lenses that are also almost twice the previous price, but probably MUCH more worth it.

Their only real competitor is Zeiss, and Zeiss are so overpriced only well-paid pros and rich playboys can afford them. ;)
