Product description

• Color Name:C/Y-EOS R
• Suitable for: 
• Lens: Contax/Yashika C/Y 
• Camera: EOS R bayonet Cameras

Note:

• 'No Lens Attached' - Warning Message Appears 
• If your camera indicated "lens is not properly installed", please modify the camera menu settings. Usually called the "release the shutter the lens is not installed", you can modify the settings to be allowed. Specifically refer to the camera manual
• Infinity focus position: the position of the infinity mark 【∞】of the telephoto lens or super telephoto lens is shifted slightly to the positive side to enable focus adjustment even when focus shift is caused due to temperature changes. The shift range is denoted by an L-shaped line, Be sure to check the focus through the viewfinder even when you shoot at infinity.
• As EOS lenses are electronically controlled，most EF mount lenses do not feature a manual aperture ring，so when used on our EOS-Nikon Z, which is a full manual operation adapter ring, the aperture could not be transferred to the camera, it will stop down to its smallest f/stop by default.
