I'm confused. :-) There's a ton of FF lenses on the market and they're not marked, and never will be. Now if the ones that were only truly APS were marked *APS*, that could be a good thing.
It's really not complicated or confusing. If you know how to use a camera with any degree of skill, and are willing to spend money on a new lens, then this issue is certainly a no-brainer. Much simpler than determining what size of wheel and tire are compatible with a given vehicle. Tom C. >From: "J. C.
