I am considering acquiring a newer model of canon's digital EOS cameras. i don't w/c model would be best that i can use my old canon lenses with.|||Unfortunately, your A1 uses the Canon FD lens mount. Canon abandoned that lens mount for the EOS lens mount when they introduced their auto focus 35mm cameras in 1985. The EOS mount is used on all Canon DSLR cameras.





However, Canon did offer an adapter to use the FD mount lenses on the EOS mount bodies. You should be able to find one at:

There is also an adapter to allow use of the Minolta MC/MD mount lenses on the Canon EOS mount bodies. (Minolta also changed their lens mount in 1985 when they introduced their AF camera. The A-mount of the Minolta Maxxum 7000 is used by Sony DSLR cameras today).





Please remember that using those older lenses will require manual focusing and likely "stop down" metering since there will be no contacts between the lens and camera body to allow auto metering.|||The "best" model depends on a lot of things. What is your budget? How serious of a photographer are you? What are your intended uses?





Canon basically has four ranges of SLR cameras.





The entry-level range is made up of the XS and the XSi (or the older XT and XTi). They're smaller, made of plastic, and cost less. You can find them for $600-$800 new. The XT and XTi can be found on ebay for cheaper.





The pro-sumer camera is the 40D (or the earlier 30D, 20D, and 10D.)


These cameras feature a metal body, are larger and are pretty decent all around. The 40D goes for about $1200 new. The earlier models can be found on ebay for $600 or cheaper. I have the 20D and am very happy with it.





The professional camera is the 5D. It features a full-frame sensor (no 1.6x crop factor). It'll cost you $2000+ new. If you're thinking about the 5D you may want to wait - there's whispers of a replacement coming out soon. If they do replace it the 5D will get cheaper.





The top-of-the-line Canon cameras are the 1D line (1D; 1Ds; Mark I, II, III). These things are HUGE. They also feature a full frame sensor as well as any other features a pro could want. The 1Ds Mark III will cost you about $8000 new.





So because I don't know you're requirements I can't tell you what you should get. Basically I suggest you figure out what you need and what your budget is and then research those cameras in that range.
