Various websites are saying the 6D sensor will actually have an advantage in low noise at high ISO vs. the sensor on 5D3.
I have an itchy trigger finger with all the $2500 give-aways on the 5D3. If the 6D were really going to stay at or around $2100.00, it would seem like a slam dunk for buying 5D3, UNLESS the new sensor really is better in low light... I realize the AF seems to have been deliberatively crippled (and overly-so!), but for shooting portraits and candids and casual soccer of my kids, I really don't need the pro athlete or bird-in-flight AF.
Plus, heck, the replacement for the 7D (7D2?) could have a wildly better sensor?
What do CR folks think of this?
I should say you can see my equipment below my name. I shoot portraits and candids of my 7-year old and 6-y-o and my infant. They do/will play some peewee soccer, but nothing challenging for another 6-8 years max! I've never met a bird who would pay fair value for an excelent portrait at 1000 yards, so I don't need too incredible an AF capability.
If your choosing between the 6D and 5D3 based mostly on sensor tech, Be prepared for disappointment.
If you choose based on the metering, AF, ergos, etc... the 5D3 is vastly superior.
