One of the best value of those tested in our database (and sadly no longer available, having already been revised and soon to be tested) is the Sigma 19mm f/2.8 EX DN Sony E. As the equivalent angle of view to a 28mm (in 35mm format), this lens only costs $140 and yet has good sharpness, low distortion and not too bad chromatic aberration. Compared to the Sony equivalent offering, the Sigma offers similar sharpness but while the former is nicely compact in size it’s at the expense of vignetting, and distortion. Not only that the Sony pancake, appealing as it is, is more than twice the sticker price.
Of all the E-mount lenses none has quite the same reputation as the Sony Zeiss Sonnar T* E 24mm f/1.8 ZA. As the equivalent angle of view to a 35mm lens, this $1000 optic is jointly ranked second with the new ZEISS Touit 1,8/32, and achieves just one point less in than the Sony 50mm moderate telephoto (a lens that’s far easier to make and correct for optical shortcomings). In fact, with a 13P-Mpix score it shares similar levels of sharpness as the Sony 50mm. It also outperforms Sony’s other shorter focal length lenses, including the 35mm f1.8 (which is the equivalent to a 50mm and one that we would expect to score highly). Distortion levels are quite low, as is vignetting. The only downside is Chromatic Aberration, which could be lower given the price.
