Shootout: Sony 12-24mm f/4G vs Zeiss Loxia 21mm f/2.8 (Pescadero Creek, Sony A7R II)

See my Sony mirrorless wish list.

What I care about in the field is predictable performance: accurate focus, minimal field curvature, edge to edge sharpness. That way I can make the image I want to make with a high probability of success. The Zeiss Loxia 21mm f/2.8 does that for me. Can the Sony do the same?

This shootout pits the Zeiss Loxia 21mm f/2.8 against the Sony 12-24mm f/4G zoom. It evaluates sharpness, field curvature, distortion and overall image quality.

Shootout: Sony 12-24mm f/4G vs Zeiss Loxia 21mm f/2.8: Pescadero Creek Overview

Includes images up to full resolution from f/2.8 through f/11.

The about $1499 Zeiss Loxia 21mm f/2.8 remains a favorite—it’s a gem in performance and size and weight. I just wish that Zeiss would make an 11mm f/4 and 15mm f/2.8 Loxia. Setting aside the relative performance, its extra stop of lens speed is a BIG DEAL in dim light for focusing.
