Infinity focus position:

The position of the infinity mark [∞] of the 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.

Note:

L mount cameras are full-frame mirrorless cameras.
Adapting APS-frame lens to full-frame camera may generate vignetting, which is not the problem of the adapter. Some cameras could correct it by adjusting to APSC.
