In my opinion, if Canon does not launch an cheaper model around 2500-3000€ with 35+MP, they will loose a lot of photographers.
Are they 'losing a lot of photographers' to the D800 now?
I'm sure there's a reasonable number of photographers who are able to recognize the image quality of D800.
Sure, and I'm among them. But I didn't switch... Where are Nikon's versions of a high quality 80/100-400, 28-300, and anything like my MP-E 65?
The 14-24 is certainly a nice lens - but 36 MP is hard on that lens' corner performance.
Just put my new 14-24mm on the d800 this weekend for a few test shots in the countryside.
Certainly does have some CA in the borders and corners but that cleans up pretty well with one click on the checkbox in Photoshop's ACR front end.
That lens is pretty good, tho not perfect. 14mm made for some pretty wide pastoral scenes tho. Looking forward to what else I can do with it.
as for Canon losing customers...
They didn't get any money from me this year. Instead I bought 4 Nikon bodies, included the 800 and the 800e, a few new high end lenses and a pile of cheaper ones.
IF Canon had just ONE FF body with as good base ISO noise performance as any of the current Nikons I would have bought it, maybe even two of them.
As it stands, more of my creative and outdoor work is going to the other camp but I wish it weren't, as I still prefer many things about using Canon gear; the appearance of the images their bodies produce, many of the fine lenses they have.
What they announce in the next few months, whether delivery is soon or in 2013, will determine what equipment will dominate my toolbox.
If they can't kill the read/banding noise even more than in the 1Dx then I'll be selling some of the Canon gear that's been outperformed by the new competition.
Invariably that means I'll be buying more from the other guys. Plenty of enthusiasts, landscapers and other non-hi-iso types will likely consider doing the same. We're not all married to our brand of tools and toys.
