Hello all, I know there are some photography enthusiasts on this list. I am considering purchasing a digital SLR camera. I bought a film based SLR camera about 6 years ago but it would seem it is time to move on. The previous camera was a Nikon F55 and I had purchased a few filters and a 300mm telephoto lens. Even though it was an entry level camera, I was generally happy with the quality of the images. In previous reading on this topic, I understand the opinion varies amongst manufacturers on the various file formats and how well they allow the RAW file formats to be extracted from the camera. The two brands I am mostly considering at this stage are Nikon and Canon. Would anyone care to comment if a Linux user is likely to have a preference for either and/or if there is another brand that is very Linux friendly? I like the idea of a camera that uses SD cards and possibly conventional batteries but that requirement isn't hard n fast. Additionally if there is some way to use my legacy 300m telephoto lens, that would also be cool but I'm resigned to it being incompatible. Thanks for any thoughts offered, just thought I'd ask. Cheers, Chris
