Take advantage of our engineering with the 1.4x optic glass that is used to make up the focal flange distance difference between the lens and camera (distance between the lens flange and film/sensor plane).This corrective lens in our adapter allows an older lens to properly focus to infinity on the newer camera body*. | 【Suitable】Lens: Canon FD Lens Compatible Cameras Canon EOS (EF, EF-S) Mount SLR Cameras - Popular models include: 1d/1ds, Mark II, III, IV, X, C, 5D, 5D Mark II/III, 7D, 10D, 20D, 30D, 40D, 50D, 60D, 60Da Rebel xt, xti, xs, xsi, t1i, T2i, T3, T3i, T4, 300D, 350D, 400D, 450D, 500D, 550D, 1000D etc...(except EOS 30, 30V & 33V) | 【NOTICE】:Autofocus, automatic aperture and AE metering will be DISABLED.
