Sigma 35mm F2 DG | Contemporary

Reviewers find it sharp in the centre wide open and very good across the frame by f/2.8. Lateral colour fringing is low, and the 9-blade aperture gives smooth bokeh for a compact f/2 lens. Like its I-series siblings it shows visible barrel distortion and vignetting if in-camera profiles are switched off.

The metal construction and tactile rings are the main reason to choose it over cheaper plastic f/1.8 rivals. The trade-offs are the f/2 aperture, the absence of a de-click option for video, and a lack of a focus distance scale.

Owners describe it as a small, well-made lens that feels at home on A7C and A7-series bodies, and many use it as their main walk-around lens. AF is described as quick and quiet with reliable eye tracking.

Recurring complaints are the audible aperture clicks during video, the magnetic cap coming off in bags, and a price that is higher than Sony's and Samyang's plastic 35mm f/1.8 lenses.
