Made of black anodized aluminum (camera body mount) and brass silver (lens mount) the KIWIFOTOS LMA-EOS_EM lens mount adapter allows the use of the Canon EF lens on the Sony E-Mount NEX Camera Body (NEX3/NEX5 etc.).
The lens fits 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). Infinite focus is guaranteed.
