Lens Review
Introduction | Sigma 30mm F2.8 DN A Sony E lens performance | Sigma 30mm F2.8 DN A Sony E Versus Carl Zeiss Planar Touit 1.8/32 Sony E both mounted on Sony NEX-7 | Conclusion

On the 24-MPix NEX-7, a camera known for its superb if somewhat uncompromising sensor, the Sigma 30mm performs well given the $199 price. Nevertheless, it isn’t the sharpest, highest resolving lens we’ve seen (the Sigma 60mm f2.8 DN A achieved a 16P-Mpix score on the same sensor/camera model). On the plus side, sharpness is reasonably consistent across the image field. Both vignetting and chromatic aberration (noticeable from 2/3rds of the image field out to the corners) are high for a lens with an f/2.8 maximum aperture like this one. Distortion is mild, though.
