Canon Lenses Digital Slr
Can the exchange between the lenses of digital SLR cameras and film?

I am looking to buy a digital SLR camera and now have a film SLR cameras. I need to know if I can just switch between the two lenses (provided they are both Canon, for example)

Yes is possible depending on the brand and type of lens. For example: Canon autofocus lens film camera (Canon EF mount) can be used in a digital SLR Canon. Its focal length field of view will be magnified by 1.6 in most Canon SLRs (ie a 50mm lens will have a field of view as a 80mm lens, when used in a digital SLR). ** Canon manual focus film lenses (Canon FD mount) can not be used on digital SLR cameras Canon AF-S ** EF lenses are designed for digital cameras only. Nikon: Nikon F-mount autofocus can be used on its line of digital SLR (you get a 1.5 multiplier so for example a 50mm lens is like a 75mm lens). Depend on the type autofocus lens and SLR body model. For example, the D40 and D40x is AF AF-S lenses Nikon AF but regular will work only in manual focus. The manual focus Nikon F-mount lenses (usually an AI or AI-S lens) is mounted in the digital SLR. Can or can not feet, depending on the camera body. ** Nikon DX range of lenses designed for digital cameras only. Sony – will Minolta autofocus lenses, but not the older Minolta MC or MD lenses and manual. Pentax – Almost all Pentax lenses going back to manual focus K-mount will mount and work some degree. Olympus – No, cinema lenses will not fit the 4 / 3 mount Olympus digital SLR. Others: Praktica, Contax, etc. Nope. Out of luck.
