I created the [full-frame]
and [cropped-sensor]
as described in this question. Both are widely used online and (at least in British) magazines and publications. Full frame is generally accepted to be 35mm equivalent, and I guess that many issues to do with the fact that a given D-SLR has a cropped-sensor will also apply to P&S cameras too. If it is D-SLR specific, then I would hope the question was also tagged [dslr]
as well.
Certainly for Canon I feel it's important to seperate whether a question is to do with lens mounts or sensor size. Tagging with [ef-s]
could relate to either, and also keeps Nikon users from the advice passed on, and we could end up with near-duplicates, with only the specific brands mentioned varying.
