There is this: http://www.photoethnography.com/equipment.html (look down a bit), but it is not complete.
Basically, unless you are using flash, all 500-series cameras can be summarised by saying that they have no metering or other features, and use only leaf-shutter lenses (C, CF, CFi, CFE) The 2000-series has a focal plane shutter and can use F and FE lenses, but still have no metering. The 200-series is a bit mixed, but some of them are fairly advanced, with metering. They also have a focal plane shutter and take F and FE lenses. Both 2000- and 200-series cameras can also use C/CF/etc. lenses.
Are you wondering which one to maybe buy?
