Lens Shootouts

There are plenty of resources to look up photos taken with a particular lens and also series of lenses (all M lenses for example). I can not find much at all though on direct comparisons of different lenses where there is an ownership choice between them, similar focal lengths for example. I'm quite interested in seeing how old lenses compare with their modern counterparts and a collection of photos all under one thread would be interesting to browse and more convenient than flitting about between several windows and websites. So I'm going to start a couple of threads that interest me and hope that others will post their photos too.

I think parameters need to be pretty focused to work. There are plenty of potential topics, eg: DA70 vs FA77, 100mm Macro comparison, zoom vs primes in range. Might be interesting, might not, might get some participation, might not.
