製品仕様

Manual adapter: without electronic contacts, doesn't support autofocus/auto diaphragm/aperture control.
Set camera "release shutter without lens" to enable when using the adapter for the first time, or the camera will fail to recognize the lens and the shutter may not be released.
Adapting APS-frame lens to full-frame camera, it may generate vignetting, some cameras could correct it by adjust APSC.
Adapting full-frame lens to APS-frame camera provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle. And it will magnify the focal length by 1.6 on Canon, 1.5 on Nikon and Sony, 2.0 on M4/3 camera.

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.

The camera needs to be set to function without an E-Mount lens attached. You can do by changing the following camera setting: 'Menu' -> 'Setup' -> 'Release w/o Lens' -> 'Enable' (Exact naming and location of this option may change depending on camera model). If your lens does not have a manual aperture control ring, it will stop down to smallest f/stop by default.
