Some old lenses will fit current DSLRs easily, eg all Pentax K mount lenses from the mid-1970s onwards will fit Pentax DSLRs. A large number of Canon and Nikon lenses will fit Canon and Nikon DSLRs, but I believe some early ones will not. If I'm wrong I'm sure others will be along to give the a better answer.
With older lenses you will lose some or all of the auto functions which may, or may not, be important.
But a few more details about what equipment you have will be helpful.
