Expand your lens choices using the Contax Zeiss Lens to Canon EF Camera Conversion Mount from Simmod. This durable brass lens mount enables you to take advantage of your existing collection of select wider Contax Zeiss lenses when using a Canon EF or EF-S-mount camera body. Designed for precision, functionality, and durability, the brass converter maintains infinity focus and proper functioning between lens and camera.

Note that mounting this screw-on converter may void your original lens manufacturer's warranty. See the chart in the product photos or the Simmod Lens site for a list of compatible lenses. Note that to make Contax Zeiss lenses compatible with Metabones Speedboosters, you must remove the rear protruding pins on your lens. Simmod Lens offers a service for this removal. Damage can be caused to your Speedbooster if it is not removed.
