This optional accessory is designed to work strictly with the EF 50mm f/2.5 Compact Macro lens. Unlike typical life-size adapters, the Life Size Converter EF actually has optics that are optimized for high magnification when combined with the 50mm macro lens. Magnifications from 0.26x (approx. 1/4 life-size) to 1.0x (true life size) are possible, at increased working distances.

This device greatly expands the use of the 50mm F 2.5 macro lens it is designed for. However, unlike an ordinary tele-converter it does not allow infinity focus. To compensate for this it does allow other lenses to be used with it as long as you don't use auto focus.
