ZEISS Loxia 21mm f/2.8 Distagon T* - Sony E Mount

The ZEISS Loxia 21mm f/2.8 Distagon T* is an ultra-wide manual focus prime for Sony E-mount cameras. It is highly regarded for its exceptional correction of chromatic aberration and distortion, making it an excellent choice for landscape and architectural photography. Despite its high performance, it maintains a small form factor consistent with the Loxia line, sharing a 52mm filter thread with most other lenses in the series. Potential buyers should check the mechanical operation of the focus and aperture rings, ensuring they move without play. The rear mount should be inspected for wear on the electronic contacts. SDS checks for internal alignment issues (decentering) which can occur if the lens has been dropped, ensuring edge-to-edge sharpness is maintained at all apertures.
