Fotodiox Pro Lens Mount Adapter Compatible with Praktica B (PB) Lenses on Canon EOS EF/EF-S Cameras

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. Adapting larger format lens to smaller format sensors (i.e: large format to medium format, medium format to 35mm) provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle. This Fotodiox lens mount adapter is made with high standard precision. The leaf spring design in the adapter holds the lens tight to the camera body ensuring there is no play between the camera and the lens. This Adapter has a built-in 1.4x Multi-Coated Focus Correction lens to adjust for infinity focus, the glass element can be removed for macro photography. This adapter allows Praktica B-System (also known as PB) Mount Lenses to fit on a Canon EOS (EF or EF-S) 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. Infinity focusing is allowed with the built-in 1.4x Multi-Coated Focus Correction Lens. 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, 1000D Actual product packaging and contents may differ from image shown due to packaging or product updates by manufacturer.
