Incredible resolution perfect for the high-megapixel era.
Introducing the new benchmark large-aperture standard lens.

Designed to offer ultimate 50 mm F1.4 performance,
this refined lens perfectly represents the ideals of our Art line.

 

Offering the best 50mm F1.4 performance in the history of photography,
this is the ultimate standard lens

Putting all of our large-aperture 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. Until this time, only camera manufacturers had produced a lens in this specification for DSLRs. Our version of this go-to lens created quite the stir at first. Earning the support of photographers with its exceptional performance, it has become one of our representative lenses. The SIGMA F1.4 DG HSM fulfills our design concept and quality requirements at the highest level. While producing a beautiful bokeh effect, it features exceptional peripheral brightness and minimal distortion. Uncompromising in every detail, this large-aperture standard lens offers the ultimate in image quality. Its high resolution makes it perfect for the high-megapixel era. Resolution is extremely crisp at the area in focus, while both front and rear bokeh are silky-smooth. Offering the ultra-high performance that characterizes our Art line, this lens inherits the design principles of the line’s first model, the flagship SIGMA 50mm F1.4 DG HSM.

High resolution plus outstanding bokeh

While maximizing resolution at the area in focus, this lens 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.

 

Minimized axial chromatic aberration

Axial chromatic aberration is difficult to correct after a photograph is taken using image processing software. For this reason, this lens features SLD (Special Low Dispersion) glass to minimize axial chromatic aberration and deliver sharp, high-contrast image quality throughout the frame.

Minimized sagittal coma flare

An ideal large-aperture standard lens offers outstanding image quality across the image plane, even at wide-open aperture. Sagittal coma flare is an optical aberration in which point light sources near the image periphery have a tail (“coma”) instead of appearing round. To minimize this aberration, we have included a precision-molded aspheric lens element in the rearmost lens group. Since it minimizes the streaking of point light sources near the edge of the image, this lens is an excellent choice for shooting heavenly bodies and nighttime illumination. In addition, its beautiful bokeh effect makes it a great go-to lens for portraits, interior shots, and many other applications.

High peripheral brightness

Large-aperture lenses are prone to reduced peripheral brightness. In this lens, we have made the forward lens group large-aperture, thereby raising aperture efficiency. The result is minimal reduction of brightness at the image periphery and even image quality throughout the photograph. Even at the wide-open aperture, you can shoot a blue sky without fear of reduced brightness and achieve a beautiful bokeh effect at the same time.

The x-axis represents image height (distance from the center of the image in mm), and the y-axis represents the relative illumination at the edge of the image (with illumination at the center of the image defined as 100%). When relative illumination is low, the corners of the image appear dark, resulting in vignetting.

 

Minimized distortion

Distortion is an optical aberration in which straight lines appear bent or curved. Since adjusting the focus cannot correct this aberration, it must be minimized at the design stage. This lens features aspheric lens elements and optimized power distribution to minimize distortion from the center of the frame all the way to the edges.
