ZEISS Loxia 2.8/21

Reviewers found it sharp in the centre from f/2.8, with very good edges from f/5.6-8, low lateral colour and strong flare resistance. Its sunstars and micro-contrast are common highlights. Distortion is a moderate wave (moustache) type that needs a profile for architecture.

The drawbacks noted are visible vignetting wide open, some colour shift in the corners on certain older Sony sensors, and the price for a manual-focus f/2.8 lens. Testers called the handling, build and focus feel excellent.

Owners describe it as a favourite landscape and travel wide because it is small, precise to focus and robustly built, and it renders with rich colour and contrast. Videographers value the smooth focus, de-click option and accessory gear rings.

Complaints include the lack of autofocus, wide-open corner softness, a mount gasket that is the only weather protection, and rising used prices after production ended. Some find the 90-degree focus throw short for precise video pulls.
