the lenses you already have. The Canon DSLR cameras can use EOS lenses whether they are made for digitals or not. You should, however, check to be sure that your old lenses will work. It has to do with the mount and controls, not whether the camera is digital or not.
I am looking at two cameras. One is the Olympus E-300
and the other is the Konica Minolta Maxxum 7D.
The Olympus uses Zuiko Digital Specific Lenses while with the Maxxum I could use Minolta lenses I already own because I have the Maxxum 7 35mm. Is a camera that takes these dgitial specific lenses better than one that will use regular 35mm lenses? I love my Maxxum 7 and the digital version has all the same features but the price is around $1,400 and it's 6.1 megapixels. My Olympus C3000 is 5 megapixels so I don't get why so much for only that many megapixels? With the Olympus I can get it right now with rebates from Circuit City online for $800 and it has 8 megapixels unless I am reading the specs wrong on these two cameras.
