I'm planning to edit the very popular How much do lens lineups vary across DSLR platforms? question to specifically mentionDSLRs, and then ask a separate one for mirrorless compact system cameras.
It happens that (due to the age of the question) most of the questions mostly refer to SLR systems anyway. In fact, that's arguably the intent of the question.
I think it will be more useful to do this and to have a separate one for the newer type of camera, but I wanted to mention it here before I went and did it. Anyone object?
