Many lenses that were originally designed for film cameras will work on modern digital SLR camers.
Purchasing a professional camera is a significant financial commitment. When changing from film to digital, save money by buying a digital SLR camera that will work with most or all of your existing lenses.
Nikon
Most older manual focus with aperture indexing (AI) Nikkor lenses will work with the newer digital SLR Nikon cameras. However, be prepared to focus and set exposure manually. Check Nikon's compatibility chart for your specific lenses (see Resources).
Canon
Canon's digital SLR cameras are compatible with all previous Canon EF lenses. Canon offers lens mount converters for lenses that are even older: the FD series.
Leica
Leica's digital SLR cameras are completely different from their film version, so Leica digital cameras do not accept Leica R-Series film lenses. However, some adapters allow you to use these lenses with Canon and Nikon digital SLR cameras.
Pentax
Pentax owners can use all older Pentax lenses with digital SLR Pentax camera bodies, although some require manual focus and exposure setting. Pentax S-mount lenses require a Pentax Mount Adapter B.
Olympus
Using adapters, the Olympus OM lenses are compatible with the E-System digital SLR series. However, there are significant limitations. You cannot manually focus OM-series auto-focus lenses on the newer digital Olympus models, and features such as spot metering, aperture display and auto-exposure will not work.
