Upload & Sell: Off
From the sounds of things, both Panasonic and Sony are in 4), heading towards 5).
I don't know how Samsung is doing in general, I guess at least 2), although their cameras are only selling modestly, AFAIK.
Olympus is probably in 3) at this point. Pentax/Ricoh? I don't know, maybe also 3)? I can't think of any in 1), apart from Apple and the iPhone camera. Fujifilm is probably in 3). Most of the medium format companies must be in 3) as well. Leica might be in between 1) and 2).
