I've had mine for 6 days, so add this to your formula as a half count.
(1) Detail recorded and cropping depth. I think that one is pretty much a a gimme. I suspect 7D might be even better than my 1DsMkII in that regard.
I pretty much think this is a gimme too. With my 40D, I could only crop a wee bit here and there for most images. I tend to shoot indoors, 400-800 ISO was my previous range. I didn't have a lot of options for cropping indoor pics. I had a little bit more freedom for pics taken outside at your 100-400 ISO range. I don't know how much further I could go with the 7D, but it seems like a ton of breathing room.
(2) Low ISO noise. When I view an image on my 19" screen, and crop a bit, say 30%, I'd like to see no objectionable noise at ISO 100, 200 and 400.
High image croppability does little for me if I end up having to do NR on low ISO captures.
After looking at a few properly exposed low ISO images, I am satisfied. I don't have a lot of this. I pretty much have been shooting at higher ISO's since I bought it.
(3) Peripheral AF sensor sensitivity and accuracy. Is it better than 40/50D ? Yes, by far. I can't fool the non center point AF sensors more than the center one yet. I actually love the AF point expansion for a little bit of help. It's a function that is far from gimmicky and really practical.
(4) Servo AF. Is it more like 40/50D or closer to 1DMkII(N) ? Or perhaps better than any of those ? (Honestly, I haven't used a Canon camera yet that would floor me with its Servo AF performance. That's where I need help more than anywhere else.)
It doesn't seem to be 1D III fast at first lock on servo (well I guess it doesn't lock), but first acquisition speed isn't quite there. Almost, but not quite. However, it doesn't "miss". In fact, it's almost frightening. Let me give a brief example. While taking a look at some ducks, I saw a beautiful small bird dart across the landscape. I'm not the best BIF shooter, but I quickly brought up my 7D to aim, and I panned with the bird hoping to get a "lock". It got it just like that. And mind you, I was using "zone af" which can be slower and less accurate then single point or single point expanded. I had my jaw drop in awe. Alas, the shutter was only at 1/500th. The little scooter's wings needed much more than that.
(5) Low light FPS. What's the real scoop here ? If FPS is exposure sensitive, where does it kick back to a lower FPS and what would that FPS be ?
Sorry I can't answer item 5. I have not shot this beauty in low light with the drive in H.
I hope this helps more than hinders. I always enjoy your posts, petkal.
--edit--clarification.
On item #2. I have a 24" display at 1920x1200. 30% doesn't seem threatening.
