Made of black anodized aluminum (camera body mount) this mount adapter allows the use of Leica Thread Mount M39 (LTM) lens on the Sony E-Mount NEX Camera Body (NEX3/NEX5 etc.).
The lens will fit physically, auto-focusing control and camera modes which control exposure by automatically adjusting aperture are not retained, however. Use the lens in the fully manual exposure mode (M), or in the aperture priority (A) mode and select MF assist function to focus accurately (7x or 14x zoom focus).
Preserve all focusing range up to the infinity point.
