Zeiss's weather-sealed 35mm for Canon — the Milvus 35mm f/2 Distagon with improved build.
The Zeiss Milvus 35mm f/2 Distagon T* ZE is a premium manual-focus wide-angle prime from Zeiss's Milvus line for Canon EF mount. ZE indicates Canon EF mount with electronic aperture control (Zeiss' Milvus 'E' series provides aperture control via camera body commands). The Distagon is Zeiss's retrofocal wide-angle formula.
The lens delivers 35mm at f/2 maximum aperture with Canon EF electronic aperture control (aperture is set via the camera, not a separate ring), Zeiss T* multi-coating, Milvus-line weatherproofed build with rubber sealing, and full-frame EF coverage.
The Milvus ZE version for Canon EF is notable for providing electronic aperture control from the camera body — unlike traditional manual-focus lenses, the aperture can be adjusted via the camera's controls, enabling aperture-priority AE mode. This bridges traditional Zeiss manual focus quality with modern Canon DSLR functionality.
Verify electronic aperture control operates correctly on a Canon EF body — aperture should be controllable from the camera body. Test Zeiss T* coating. Inspect rubber weather sealing at mount and barrel. Check focus ring smoothness.
