Just to add to that, didn't the sales indicate that both the lower end (Rebel) and high-end (5dIII & 1DX) categories both belong to Canon? I would think that photogs in the 'pro' class would of done their homework, not just go out and blindly purchase.
Actually, In the pro market I would expect them to look at the combination of camera and lens..... and I think we all have to admit that Canon's selection of high end L glass makes it onto our "if I won the lottery " list.. This has to be a big factor for a pro deciding which way to lean.
Exactly, couldn't agree more.
As does service centre quality, and ubiquity.
If you're a pro journalist, and the equipment locker at the office is all white lenses, having a Canon body is likely going to be your choice. Similarly, if you're the owner of the same pro equipment that you need to photograph events, knowing that if it goes down, you'll have it back in a matter of days, is crucially important.
Finally, Canon selling the most DSLRs is a good benefit to us Canon shooters, as it enables Canon to put more money in to R&D, giving us better lenses and bodies.
