Sigma 50mm F1.4 DG HSM Lens for Sony E-Mount

High Resolution Plus Outstanding Bokeh

While maximizing resolution at the area in focus, this SIGMA 50mm F1.4 DG HSM Art lens for Sony E-mount 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 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.

HSM (Hyper Sonic Motor)

HSM (Hyper Sonic Motor) delivers high AF speed and extremely quiet performance. An enhanced algorithm offers even smoother automatic focusing. Optimizing AF algorithm, smoother AF is achieved. Also, new firmware offers 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.
