Notes:
-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 allow. Specifically refer to the camera manual.
-Adapting APS-frame lens to full-frame camera, it may generate vignetting, some cameras could correct it by adjust "APSC", please consult us and provide your lens&amp;camera model to check the way to correct it. 
-The position of the infinity mark (infinity)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.
