High Resolution Plus Outstanding Bokeh

While maximizing resolution at the area in focus, this SIGMA 50mm F1.4 DG HSM Art lens for Sigma SA offers a silky-smooth bokeh affect to the front and rear. To achieve exceptionally crisp resolution, we have minimized sagittal coma flare, chromatic aberration, and every other type of optical aberration that affects image quality. The result is minute detail without bleeding or streaking, even at wide-open aperture. Moreover, we have also minimized both vignetting and color streaking to the front and rear of the area in focus, thereby establishing a bokeh effect that is natural and aesthetically pleasing.

Minimum Focusing Distance Of Just 40cm

SIGMA’s floating system adjusts the distance between lens groups during focusing, thereby reducing the amount of lens movement required. The result is less aberration at different shooting distances. Thanks to this system, this lens offers a minimum focusing distance of just 40 cm, a maximum magnification ratio of 1:5.6, and superb image quality at every shooting distance.

Minimized Distortion

This lens features aspheric lens elements and an optimized power distribution to minimize distortion from the center of the frame all the way to the edges.

Incredible Resolution Ideal For The High-Megapixel Era.
Introducing The New Benchmark Large-Aperture Standard Lens.

SIGMA was the first lens manufacturer to introduce a 50mm F1.4 lens. Now, to create the ultimate go-to lens, we took optical performance and image quality to the limit. The result is a true icon of SIGMA quality. Fulfilling the concept of our Art line at the highest level, the SIGMA 50mm F1.4 DG HSM Art Lens for Sigma SA is a large-aperture standard lens that delivers top performance. Its outstanding resolution makes it ideal for the high-megapixel era. It delivers exquisitely balanced images with a beautiful bokeh effect, setting a new benchmark for large-aperture standard lenses. It is the ultimate expression of the 50mm F1.4 specification, known to bring out the photographer’s unique personality and approach. Once you own it, you’ll never want to be without it!

Offering The Best 50mm F1.4 Performance In The History Of Photography,
This Is The Ultimate Standard Lens

Putting all of our largeaperture lens development know-how into this lens, we’ve minimized optical aberrations and achieved the very highest level of optical performance. A 50mm F1.4 large-aperture lens offers an angle of view similar to human vision, a beautiful bokeh effect, and expressive versatility. It’s a basic specification that lets photographers take many different approaches to their craft. For this very reason, it demands a high level of fundamental performance. SIGMA has designed lenses especially for digital SLRs since they first appeared on the market. In 2008, we first introduced the SIGMA 50mm F1.4 EX DG HSM. Although compared to the lenses of today it had a fairly large body, this lens offered uncompromising performance and embodied our ideal of the standard lens.
