They'll fit, but maybe not work "successfully" for you. Besides the crop factor issue, the various series (screw mount, M, A, etc. ) will have various degrees of their original (on their intended bodies) functionality, so you have to research a little to determine whether you'll find the functionality of a given lens on your body would be acceptable. Different people have different opinions - it's a matter of personal preference.
