Say goodbye to cheap, flimsy adapters and say hello to the SIMMOUNT EF Conversion Kit!
Designed for precision, functionality, and durability, our EF Conversion kits will allow you to make the most out of your existing collection of Contax Zeiss lenses. The SIMMOUNT System allows you to mount native Contax Zeiss lenses to any Canon EF/EF-S-mount camera or EF mounted motion picture camera. State of the art CNC construction ensures a tight fit, while maintaining infinity focus and proper functionality between camera and lens.
The SIMMOUNT System is made of high quality air craft grade aluminum, anodized in matte black to reduce glare and reflections, and backed by a lifetime replacement warranty.
Please note that in order to make Contax Zeiss lenses compatible with Metabones Speedboosters, you must remove the rear protruding pins on your lens. We offer a service for this removal. Damage can be casued to your Speedbooster if not removed.
Installation is as simple as 1-2-3:
WATCH: HOW TO REMOVE SCREWS
1: To avoid stripping the screws, we strongly recommend using a soldering iron to apply heat to each screw before removing them. Make sure you use the proper JIS size screwdriver. We are not responsible for stripped screws.
Hold the soldering iron on each screw for 3-5 minutes to dissolve the glue applied to the screw from the factory. Remove the screws.
2: Once the screws are removed, simply place the SIMMOUNT directly on top of the native mount. Make sure the SIMMOUNT logo aligns to the top of the lens and all the screw holes are matched.
3: Use the supplied screws to tighten down the SIMMOUNT. Do not overtighten.
