So I finally got myself a macro lens. A Canon compact-macro lens 50mm. It seems to be working great but I know this lens has been around for awhile. It's an EF lens so it will also fit a 35mm film camera. I was also playing around with an older style EF zoom lens, 75-300mm on my Canon 400D. (not the best zoom lens, I know.) Does anyone know if the image quality is hindered anyway when using these lenses on a DSLR? Should I get rid of them, or what? (Trying to save a few pennies as you can probably tell.)
Thanks.
