I can't help but chuckle at the state of affairs on this forum now. For years I coveted a 5Dmkii but couldn't justify getting rid of my 7D to do it. After all the 7D AF system is "light years" ahead of the antiquated 5dmkii AF system. I read hundreds of threads and posts dedicated to how bad the mkii AF system was/is. The general consensus was just giv us a 22mp (who needs more, right) 5D with a better AF system. Well Canon delivered exactly that. What's the old saying? Watch out, you might get what you asked for. I'm still amazed at the pictures a lot of you have gotten with your 5D mkii and it's antiquated AF system.
So what exactly is needed on the 7Dmkii ? Just better DR? More MP? WiFi? Espresso maker? Remember the warning (it's in bold above).
P.S. I'm busy saving for a 5D mkiii and I am soooo loking forward to getting my hands on it, even if it doesn't have enough DR/MP/WiFi/whotsits/thinga-mabobs.
5D3 IS great other than it's hard to believe they actually slightly regressed on low ISO image quality after half a decade which was very disappointing (and it wouldn't been awesome had it had dual digic and 30MP and still 6fps, maybe the new digic takes too much power or is too large, who knows, hopefully not thinking about future models or maybe they still can't do line-skipping free video above 22MP) and it's just plain silly that they yet again crippled AutoISO in pathetic fashion (maybe ML can fix it). (They also didn't make nearly as much as they could have for video, although now with ML we finally have zebras, better histograms and focus peaking so that is now partly fixed. Still lacking crop modes, clean HDMI out, better codec settings and bitrates and while the GH2 seems a bit too video-like crisp the 5D3 seems kinda softer than 1920x1080p. ML might fix the codecs settings and bitrates hopefully and probably clean HDMI out, crop modes might be more doubtful sadly since they haven't figured out how to code the Digic image processor and chip readouts.) But for stills other than a kind of outdated sensor for low ISO it is a great cam and delivers what was asked (and for video it did deliver the moire-free video). For shooting when it has enough reach and you don't need tons of DR it's absolutely awesome.
The price on the 5D3 did seem a bit high at intro since it didn't also bring along top low ISO DR, although it's now settling more into $2800-3100 range which seems perfectly fine.
7D2 could use the new 5D3 AF (and of course the improved low ISO that they haven't seem to be able to do an get rid of all the vertical banding, on the 7D it can even show in mid tones to one degree or another on many copies) and the improved video. (the 7D AF was not all that, I trusted the 5D2 center point more for one shot and for some sports, like soccer, I swear the 5D2 more often did better than worse for AI Servo than the 7D, although for surfing the 7D did great AI Servo much better than 5D2; 5D3 generally does much better than 7D for AF, the only place they seem the same is for surfing).
Even with the 5D3 out there the 7D2 still makes sense because at only 22MP FF the 5D3 simply doesn't have the reach needed for some things (and 8fps certainly doesn't hurt either).
