Hello,the longer Flange distance lens to the shorter Flange distance camera, then could use the infinity focus,but if the shorter Flange distance lens to longer Flange distance camera, then could not use the infinity focus, you can focus on a limited distance.  

The minimum interpupillary distance for the TrailSeeker ED 8x42 binocular is: 56mm (2.20") 

Dear friends. the maximum distance is 9.32ft for best display. 

This will work on any 82mm lens.

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.
