Instructions for use:

Attention:
1.Manual adapter without autofocus or aperture ring.
2.Skillful installation, don't too much force.
3.Adapting an APS-frame lens to a full-frame camera may generate vignetting, some cameras could correct it by adjusting APSC.
4.Adapting a full-frame lens to an 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
