With the recent release/announcements of new Canon bodies and seeing numerous posts with opinions on what segment of buyers these cameras are intended/best suited for, it starts me wondering this.
Who is the biggest buyer group for the likes of Canon and Nikon?
People say the 1DX3 is intended for professional sports photographers, shooters who earn their living using that tool. How many of these people exist? Is it enough for Canon to recover all costs and go on to make a profit if the bulk of this model sells mostly to pros?
Does Canon maybe sell 10 times as many Rebel cameras and that represents the main line of profit?
Could Rebel line sales support the R&D costs of everything else inside Canon (not cinema)?
Anybody here have a top level Canon executive they can text for insider answers?
