Overview

The Sony DT 35mm F1.8 SAM is an affordable, lightweight prime lens for APS-C Sony Alpha cameras, offering a normal field of view. Optically, it delivers excellent center sharpness and good edge performance at mid apertures, with well-corrected lateral chromatic aberration and low distortion. Weaknesses include soft edges wide open, noticeable vignetting at f/1.8-f/2, and some coma. Build quality is average, with an all-plastic barrel and mount, and a slightly wobbly extending inner tube. The SAM autofocus is reasonably fast but not silent, and manual focusing is tricky due to a tiny focus ring. It suits budget-conscious photographers seeking a compact normal lens for general, portrait, or low-light use.
