Determining Lens Selection
Select a lens using the Lens Selection Chart. The chart also indicates if
you need an extension ring. An extension ring decreases the distance
from the lens to the part and causes a smaller field of view.
Lenses used for 35mm SLR cameras are more preferable with the VS-1
Smart Camera than standard C-mount lenses when performing accurate
measurements. Lenses for 35mm SLR cameras are more optically

need to use a C-mount to F-mount adapter.
