Sony DT 35mm F1.8 SAM: Test and review of an inexpensive Sony prime lens

As usual, we tested this 35 mm lens on many Sony Alpha cameras. On a Sony A580 camera body, for example, the Sony DT 35mm F1.8 SAM lens showed a globally good performance from f/1.8 to f/5.6. The resolution is homogenous over the field of view at f/5.6 and f/8 — satisfactory for an APS-C lens.Although vignetting is an important problem at f/1.8 and f/2, it disappears between f/2.8 and f/22. And there is only a negligible amount of distortion and chromatic aberration.Side-by-Side Comparison:Compared to a similar budget prime wide-angle lens from Nikon, the Nikon AF-S DX
