Introducing the new benchmark large-aperture standard lens.

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 [A012]” 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.

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.

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.

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. Also, this lens can offer full-time MF function by rotating the focus ring of the lens while auto focusing. Without changing the AF/MF Focus Mode Switch, it allows faster focus adjustment.

New Additional function added to “SIGMA USB DOCK(optional)”

With the optional SIGMA USB DOCK, you can update your lens firmware, adjust focus points and customize the setting of Full-time MF function and the timing to operate the Full-time MF function. By attaching this lens to a SIGMA USB DOCK, which is connected to a computer, the dedicated software “SIGMA Optimization Pro” offers various types of customization and adjustment.

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.

Durable, Image quality, Quality construction, Easy to use, Sharp focus

The list of advantages of the tested Sigma is really impressive; add to it the fact that it can compete on equal terms with the Zeiss Otus, a device four times as expensive, and in some categories (e.g.


Overall, with this lens Sigma have created a lens which performs well in terms of sharpness and other optical attributes, for a fairly reasonable price. This combination of price versus performance will almost certainly win many fans for this lens, even despite its large size and weight for a 50mm...

Camera Labs

The Sigma 50mm f1.4 Art is without a doubt a very high quality standard lens with autofocus for Canon, Nikon, Leica L-mount or Sony full-frame cameras. You’d expect it to out-perform the cheaper Canon EF 50mm f1.4 USM and Nikkor 50mm f1.4G lenses considering it’s roughly twice the price, but the big...

PC Magazine

The Nikon AF-S Nikkor 50mm f/1.4G is a fast-aperture standard-angle lens for Nikon D-SLRs. It's tack sharp, even at f/1.4, and earns our Editors' Choice award.

DP Review

The Sigma 50mm F1.4 DG HSM | Art is distinctly large, heavy and expensive for its type. However this is more than made up for by its fast silent autofocus, solid build quality, and absolutely outstanding optics.


Ooops ... they did it again! ;-) Sigma proved once more that they are no longer a company providing budget lenses but are playing in the top league indeed. The Sigma 50mm f/1.4 DG HSM | A (Art series) is a cream-on-the-cappuccino product - at least when used on APS-C DSLRs (well, *hint* it's not bad...

The Digital Picture

There have not been many Sigma lens announcements that generated the anticipation that the Sigma 50mm f/1.4 DG HSM Art Lens announcement generated. The 50 Art Lens was announced not long after the Zeiss Otus 55mm f/1.4 Distagon T* ZE Lens arrived, delivering a not-before-seen high level of...

Photography Life

Similar to the excellent Sigma 35mm f/1.4 Art that I have numerously praised here at Photography Life in the past, the Sigma 50mm f/1.4 Art definitely deserves the high praises. Unlike its predecessor that fell short in a number of ways when I put it against other 50mm primes, the new Sigma 50mm...


Sigma has added to their 'Art' range of fast aperture lenses with this new 50mm f/1.4 lens, which will be available to fit Canon, Nikon, Sony and Sigma SLR cameras. This lens costs around £850, which seems like an awful lot for a 50mm f/1.4 lens.

If you shoot a lot at wide apertures (1.4 to 2.8) no 50 can beat it. I\'m still amazed when I chimp my images. As an old Leica-M shooter, I have a style that relies on lenses in the 28mm to 75mm range. My basic lens is the 18-35 Art, and this 50 is my \"long\" lens.

Wex Photo Video

Another great lens from Sigma, they really are producing some incredible glass at the moment. I've got the 35mm and the 50mm and they are both pin sharp and create some great images. 50mm is my go to for close portraits now.


I use the lens mainly for low-light and night photography in the Yorkshire Dales. It's immensely heavy for a 50mm lens, but the optical quality is outstanding - pin sharp from corner to corner from f2 upwards. I don't mind the extra weight when I can get such high quality images.

UK Digital

Fantastic lens and well worth the money, do lot's of shooting in low light situations and this really catches sharp images even if there is a lot of light and dark contrast. Essential bit of kit for concerts etc. Bokeh is brilliant for portrait shooting.

Wilkinson Cameras

The Sigma 50mm f1.4 art lens is one of the best lenses available, great all over sharpness no discernable vignetting on my full frame camera, I can recommend this lens to anyone looking for a nifth 50 to add to their bag.

Great lens, IMO best 50mm lens for full frame cameras.

LoCA is not acceptable for such a heavy lens. Sharpness helps nothing when LoCA occurs. This lens doesn\'t have weather sealing, and its walking distance is too far to make it a all-round lens.


Amazing product pleased with the outcome and quality of finished images it produces
