Do we know what the "cutoff" aperture is? AFAIK, ever EOS D-SLR shows DoF at f/2.8 or slower, perhaps this has built in support for quicker lenses? Or there's a CFn to set the screen to "emulate" the EE-s (I think that's the fast lens screen)?
Just a thought, because I've not read anything that states either way.
It would be REAL handy for me to have the gizmo project 4:5 crop marks on the sides.
According to the dpreview preview (page 12) you can specify different aspect ratios of 6:6, 3:4, 4:5, 6:7, 10:12 and 5:7. One would hope that the "gizmo" (as you refer to it) would project grid lines for those ratios (but I didn't see any evidence of that).

I was planning on upgrading to the 5DmkII, but I was underwhelmed with what Canon did with it. I'm not really a high ISO shooter. Keeping my old 5D and upgrading the 40D with the 7D might be the way to go, at least until the 3D is announced.
I am a high-ISO shooter, but I'm not sure the 7D will have the AF I want. Right now I'm very unhappy with my 40D AI Servo in low-light, and I was hoping for high-ISO performance closer to the MkIII. I'm going to wait for some real tests, but I think I'm going to conclude I should get a used MkIII, which isn't a whole lot more than a 7D+grip.

I don't know about you but after using MF for over 30 years I was glad to go to AF. I sometime MF when the need arises but I have never needed a special screen to do so.
Crop lines for various aspect ratios sounds fantastic. I usually do all my cropping in post (since the lack of full coverage on my XT always give me images that I need to crop in post).
Its also weird that people accept not getting accurate DoF from their Viewfinders. Lets go even farther, remove the Viewfinder alltogether and just display a Live View feed on the LCD with the AF points. There's no point in fine tuning focus if you're going to be totally reliant on the AF.

I don't mind carrying it around on vacation and I don't find it a PITA. But I sure don't need changeable screens or MF for vacation shots either.
Cheers
i get many of my bet shots on vacation and have needed to rely on MF or liveview MF at times.

If the per pixel resolution is as good as my 40D, then my 100-400 maximum reach will have gained 200 mm. If they are claiming 2 stops of generally improved noise performance, then how much better noise performance would the 7D's sraw be than my 40D's equally sized raw? I hope this lives up to its specs.
I have not been too tempted to trade up my 5D 1 for the mk 2 since its 12.8 MP and noise levels have not needed improvement for my use. At the wide end of things you crop with zoom and time is on your side. A crop camera with long telephoto is another story - more pixels is more reach and better SNR means more shutter speed. Better AF and movie clips too! Waiting for the reviews....Show more →
probably not quite the per pixel, especially with that zoom, but it will surely deliver a lot more reach all the same
no way 2 stops better noise for the 7D over 40D (even the D700/5D2/D3X don't quite have 2 stops better )

OK, so assuming I record in "vga" resolution, if I convert that to an mpeg-2 standard def DVD will the aspect ratio be correct? Anyone have any idea if the results would be reasonably good?
DVD doesn't have a set aspect ratio so that can't be ansered.
vga mode on the 7D is 4:3 though
it's other modes are 16:9
SD TV is 4:3
HDTV and EDTV are 16:9
movies are usually 1.85:1 or 2.35-2.40:1 but some have been 2.20:1 and 4:3 and so on I think some european movies use some weird ratio that i dont recall.
computer monitors for some odd reason are usually 4:3 or 16:10 (not 16:9 like HDTVs, somewhat annoying for the ones that don't letterbox but forceably stretch external inputs)

Wow I missed that one... Will see but in that case I'm sold on that, the focus and the flash controller from the popup

I did some pixel-peeping tonight at the Imaging Resource samples.
Compared only ISO-800/NR-off samples of the 40D vs. the 7D.
The 7D seems to have identical noise as the 40D at the pixel level.
Maybe a hair better. Certainly not worse, which was my concern.
That should translate to somewhat less noise at the image-level.
Detail is obviously better on the 7D.
The noise also has different characteristics on the two cameras.
I would say that it’s more film-like on the 40D because of the coarser grain.
On the 7D the noise is finer and grittier and at 100% crops looks worse than the 40D noise. At normal viewing sizes and distances, though, it's less visible.
Another interesting thing - the 7D renders colors differently from Canon's recent cameras (or maybe just the default 7D settings are different?).
In the 7D Canon seems to have gone back to the 30D colors. Don't know what the reason is for that.
These colors are certainly closer to the D300 colors than to the 40D/50D colors.
