To put it another way and speaking from personal experience, Pentax introduced the K series body and lens in 1975. Any k-mount Pentax lens can be mounted properly and without any adaptors to any modern Pentax dslr.
Do you know what is involved with using an older, manual focus lens with an aperture ring when used on a digital Canon body?

From what I read, they changed the EOS mount in the late 80's, so anything built before that is a no go. I think there might also be issues between older EOS lens and newer ones. But since this is my first Canon...I'm not really the to ask hwoever I am loving my camera.
