Originally posted by George Lama Getty has a list of approved cameras while other stock photo places do not (iStockPhoto and Big Stock)
Getty lists the following as approved:
Canon EOS: 1D(Mk1,2&3), 1DS(Mk1,2,2n&3) 5D, 30D and 40D
Nikon: D2X, D2Xs, D3, D200, D300
Leica M8
All medium format backs
That list is not the most up-to-date one. For example,
even the Leica X1 point and shoot is approved by Getty for image submissions now, as is the K-7 if I recall, the Sony A900, and even stuff like the Olympus E-3.
Unfortunately Getty have their full list behind a registration system now, so it is hard for me to find an up-to-date list without $##@!! registering with them.
