Flat ports are recommended for standard, macro and telephoto lenses. Due to refraction, flat ports reduce the angle of coverage of a lens and magnify the image. This makes the flat port ideal when using standard, macro or zoom lenses to shoot small subjects.
This port is designed specifically to provide manual focus with the 70mm f/2.8 EX DG macro lens. Manual focus only.Where to buy
