If you have a SLR or DSLR camera and other maker/mount lenses, the Fotodiox Mount Adapters allow you to use your lenses on the film/digital camera body. Sharing lenses has some distinct advantages. Certain prime lens just can't be replaced, and you save the cost of purchase on new lenses. Fotodiox offers a range of adapter from large format to smaller format digital adapters.This lens adapter is made with premium grade metal. It is nicely polished and anodized black to have its professional appetence to match camera body as entirety. This Fotodiox lens mount adapter allows Hasselblad V-Mount lenses compatible to 500 / 2000 / 200 / 900 (Except for H-series) series bodies to fit on a Canon EOS camera body.Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode with the Canon EOS Mount camera body. Infinity focusing is allowed.Compatible Cameras (including, but not limited to): 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, 1000DActual product packaging and contents may differ from image shown due to packaging or product updates by manufacturer.
