Or, how to build an SLR system without spending much dough.
Clever people will tell you to choose a camera system by selecting your lenses first. This I did. Several years back I got the wonderful Canon 100mm f2, a 50mm f1.8 Mk1, a 24mm f2.8 and a 28-105 zoom for when I felt lazy. Most of them second hand bargains. These I used with an eB*y bargain EOS 50E body, and all was good in the world. Then I went out and bought a 300D and all my carefully selected focal lengths were wrong. The 24 was no longer wide, the 50 was almost but not quite long enough to do the job of the 100 while the 100 was at the same time, way too long and not long enough. Time passed and the 300D made way for a 20D, which is great except it has the same problem. Curse those cropped sensor DSLRs. I've been putting up with this for 6 years. But no more. As of today I've traded my 20D for a used 5D and all my lenses work properly again. Yay! At Todd's suggestion, I'm posting the first pic from the 5D, a test shot snapped just before we went to the pub. As I recall the first pic from the 20D was a bit rubbish too!
