Review Summary
2025-02-11T07:12:59
Image quality at F1.2 is not on par with high end lenses in the L-mount. Once stopped down to 1.8 or larger, the lens is satisfactory. The Image quality of this lens is more suited to videography, or social media content than it is print work. The aesthetic design of the lens is even more cluttered in person than it appears in images. This lens has text, branding and labels?everywhere. In Summary - this is a value lens with a faster aperture, and smaller size than other options

Pros: At f1.2 you get narrow DOF Noctilux-like images with crisp microcontrast and super creamy bokeh. At f1.4-f2.8 the images rival or easily better any 50mm f1.4, f2, or f2.8 prime (including Sigma's outstanding 50mm f1.4 II) At f4-f8 you'll have razor sharpness that would get Ansel Adams to weep. With Sony's latest mirrorless cameras the AF is lighting fast, VERY accurate and silent. Cons (sorta): Okay it's heavy. 2.9 lbs with the A7CR I bought with it and battery. That said, the grip that comes with the A7CR makes the lens far less unwieldy and VERY manageable. (Cradling the lens under the barrel helps.) Final thought: If you've ever lusted for a Leica M11 and a 50mm Noctilux save your money. The 61MP Sony A7CR + Sigma 50mm f1.2 delivers the same results with higher hits. (Of course if the Leica "experience" is what you lust for, then this review won't make any difference in your wish list now will it?)

Just received it a couple of hours ago and shot some test shots around the house and outside. The focus is super-fast and quiet and tack sharp. Shooting at 1.2 produces creamy bokeh. Tilting it up and down from level with the ground you can feel and hear a very slight rattle when the camera is off but it tightens up as soon as you power the camera on. I assume it's the new dual HLA focusing system. Overall, it's top notch.

I’m a little concerned. Twice my camera alerted me that my lens was not attached when it actually was. Otherwise this lens is super awesome! The 1.2 aperture creates some great, high quality images. I also love the weight of this lens.

First wide-angle AF lens with F1.2 maximum aperture for the full-frame Sony E-mount and L-Mount system. This lens enables a creation of artwork with astounding resolution and large bokeh effects, such as portraits that make use of a shallow depth of field. It brings the development concept of the Art line “pursuit of ultimate image quality” to the next level. While utilizing optical correction function inside the camera, aberrations that are difficult to post-process are thoroughly corrected thanks to the optical design and it thereby enhances resolution.

The "Art line in the age of mirrorless cameras" pursues ultimate performance as a large-diameter lens with a focal length of 35mm and also achieves a maximum aperture of F1.2. Three SLD glass elements and three aspherical lenses including a double-sided aspherical lens are optimally arranged in a lens construction of 17 elements in 12 groups. In addition to the optical design that makes use of the characteristic of the short flange focal length, it effectively takes advantage of the correction function inside the camera to correct distortion and peripheral illumination. Various aberrations that are difficult to correct by post-processing, such as sagittal coma flare, are thoroughly corrected by the compilation of the optical design technologies that SIGMA has cultivated, achieving an overwhelming resolution that can resolve over 50 million pixels.

In autofocus photography, comfortable shooting for a F1.2 large-diameter lens is achieved by the large hyper sonic motor (HSM) that gets desired torque required to drive the focus lens group. In manual focus photography, the focus ring driven by the focus-by-wire system with the optimized torque setting responds to fine operations of the photographer.

The aperture ring(①) is also mounted with a de-click function for removing clicks by the Click ON/OFF Switch(③), enabling seamless operations that are especially useful such as during video shooting. Furthermore, the AFL button(②) which can be assigned with various functions widens the range of operations available on the lens.
The lens features the dust- and splash-proof structure additionally with the water- and oil-repellent coating on the frontmost surface of the lens, which also supports shooting in various environments.

Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality. The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens. The HSM (Hyper Sonic Motor) ensures high speed and quiet AF. The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image. From 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 back lighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in back light conditions.Compatible With Lens Aberration Correction.

It takes three things to make outstanding lenses. The first is fine design. The second is precise manufacturing. The third is inspection. SIGMA's new lens lines deliver at the highest level on all three counts. First, they are designed to embody concepts that radically redefine the relationship among the photograph, the lens, and the photographer. Second, they are manufactured in Japan with SIGMA's vertically integrated production system and the most advanced production technology. Third, they are verified using unique performance-evaluation metrics and techniques, developed from the ground up by SIGMA, ensuring the highest level of expressive performance.


Having taken our lenses to a new level of performance, SIGMA has adopted a simple product identification strategy that makes it easy for the user to identify the kind of lens for which they are looking. Building on this idea, we've reorganized all our lenses into three product lines, each characterized by its own clearly defined concept. From now on, every new lens we develop will be assigned to one of these product lines. This new system is designed to make it easier for users to access the lenses they need.

Based on these new product lines, we have developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus . The focus limiter is also customizable for Sports lenses. Using special USB Dock, the user will be able to connect the lens to their PC, and, using easy-to-operate on-screen controls, fine-tune focus and adjust other parameters to suit their personal preferences.
