Probably means most 7D and 1Dx ownersAnd birders are using the 5dIII? Nikon users would get a D7000 or perhaps even a D4. Its not like Nikon only makes the D800 and has abandoned every market but it. By comparison, your 7D would be pretty poor for landscapes compared to a D800E; but, you don't see people ripping you for that, because nobody bought a 7D to go shoot tripod-mounted landscapes. You knew what utensil you were getting; D800 owners do too
If you read the thread you would have seen that I said the d800 was no good for wildlife/sports as it was suggested that the D800 was the best camera
The 5DIII was not in the discussion - but I would guess most birders use the 7D or 1D series
Landscapes were not mentioned in the discussion either - but now you mention it I might take a 1DX for a landscape.
You have no idea what kit I have - so I will ignore the personal remarks at the end
