People are getting disappointed when D800 and 5D3 released. 5D3 is overpriced and looks D800 is better than 5D3 from many reviews. If Canon is just want to make money from its existing customers, Canon will see many of its customer switch to Nikon. I am one of the Canon users considering to switch to Nikon
Here is my true reason. I want to switch Nikon is not because Nikon makes better cameras. I want to switch to Nikon because Canon disappoints me. I feel Canon want to take advantage from its existing customers (at least me) I know many PROs have too many Canon lenses, so that will be very difficult to switch Nikon. However, Canon will see Nikon gets many of its non-PRO users.
+1 to that!
I have been a Canon non-pro user ever since my first DSLR [350D/Rebel XT] to my current 7D and this is exactly, where I stand now.
Nikon has scored big time with the D800. The 5D3 is not bad, but essentially only what the 5D2 should have been from the start (adequate AF-system). Sensor-wise its a minimal improvement. And it gets blown out of the water by the D800 not only in terms of resolution but more importantly to me, in DR at the most used lower ISOs. There is no doubt whatsoever that the 5D 3 is way overpriced while it outta be less expensive than a D800.
If Nikon now doubles that up with a D600 at around 1.5k and if its sensor also creams the 5D3 - which I fully expect - than Canon will indeed "be toast" in the all-important non-pro, photo-enthusiast segment of the market. That is us, the guys who buy by far the largest share of higher-end, high-margin lenses and speedlites, as well as future cameras. :-)
Especially "FF upgraders" coming from Canon APS-C with mainly EF-lenses, that they need to sell anyway, WILL be switching to Nikon in large numbers, as soon as a good, affordable D600 comes out. And while Nikon glass was generally somewhat more expensive than comparable Canon glass up until about 4 years ago, it has turned the other way round by now after many rounds of massive Canon price hikes.
