I am in the same trouble as you, I own quite a bit of glass for my 5D2s, and agree fully with you, Canon is on a very bad slope.... The sensors are crap compared to Sony/Nikon, the AF systems are prehistoric, not talking about pre-war light metering or middle-age flash system. The only thing that speaks for Canon is (sorry WAS) their glass, but since years they just release version 2 of what's already existing. Canon Creativity is about zero, Nikon has improved quite a bit on glass and their prices are decent.
If you take the 28mm f2.8, the old version sells for 200 euros when the new one is 650 euros?? 3 times the price for a basic 28mm? New 24-70mm twice the price of the old one? I don't know what kind of drugs they are on at Canon's but it looks pretty strong......
The 6D is not even for sale it already looks like a joke compared to the 600D and guess what ? It's not available; by then the D600 will cost 300 Euro less....
I switched from Nikon when the 5D2 appeared because it was a revolution (sensor speaking), knowing that everything else was worse than my D200 with it's crappy sensor. As I use a tripod 95% of the time I can cope with the drawbacks. The 5D2 was not a revolution, it was a single event. Canon has not been able to release one camera that competes with Nikon since then (except maybe the 7D).
I really think canon takes people for stupid, they release the 6D with an integrated WiFi/GPS combo, but they charge 500 Euro (WiFi) + 250 Euro (GPS) for the 5D3 accessories. In 4 months they made such a technical progress that they could put it in their mid level camera but not in the Pro ones. Not that I think these features have any use in photography, but for the principle.... They just think we are MORONS.
i cannot believe how many fanboys here are finding excuses for an AF system like that that is what, 10 years old? when nikon on the other side is offering PRO-AF on even their lower-end cameras.
As long as people using canon products won't complain canon will keep using this kind of, sorry for the french, sh*t policy with their new products, not giving a damn of what the offer is like on the other side of the market.
I've always shot canon and probably always will since i like more their lenses but this doesn't mean that canon shouldn't try to offer a camera of the same level of a D600 if it's going to price it the same for instance; canon sensors are already a joke compared to the latest sony ones, they should've at least make some effort on some other aspects (and please don't mention wifi/gps)
