^ I agree, you cannot take somebody else's shot and compare to one you have taken, to be completely scientific and accurate, you would have to have both bodies take the same exact shot in the same conditions, then compare.

This is why it will be really interesting to see how those that have 5D and 5DII fare when they pick up the 7D as their crop backups, there will be a TON of threads comparing ISO between the bodies. Part of me can't wait, but the other part dreads it due to all the threads and arguments.

Seconded!

Thats why i cant compare the 30D stuff on I-R's site either because they changed their lighting setup....Also they didnt run the same tests and etc..

To be a valid comparison you have to make the only variable the camera, All other things MUST be equivalent...

On most of the samples I've seen, the 7D looks about 2 stops behind the 1D MkIII as an example. I'm not really very impressed. Granted they are different crops but I think it's a fair comparison. I can post up an ISO3200 shot taken at 1/30s that still looks about 1 shot better than the 7D examples I've seen.

7D, ISO1600 (external link), Resized to 10MP

1D MkIII, ISO1600 (external link) NR Off

And for the original post, the colour isn't better on the D700, it's just more saturated. Canon has changed the processing of the 7D to be less saturated and more neutral than in the past. It has nothing to do with the ISO in this case.

Hey, no fair using a 1Dmk3 shot that's been run through FlexNR!

;) :D

has anyone compared a 5d2 and a 7d at a usable iso of 800 on the womans picture. the 5d looks like a p&s by comparison-surely something wrong there.

Ugggh...in camera NR = Not a picture I want to see...
High ISO shots using very well lit stage subjects, means not a whole lot.

could it be a focus issue?

As said, this comparison is completely useless.

Is noise performance at 6400iso REALLY that important to people with this camera? Honestly, how often do people shoot up there? Nice for it to perform well, but it aint a deal breaker is it?

I simply can't understand why high iso performance is such a biggie for people. It's taken over from megapixels as the next big marketing gimmick!

Longtime lurker here.

Why? Try shooting a stage performance that has ONE stage lantern... and that has a red gel on it. I'd have given anything for useable 6400! I managed to eke some shots out of the situation at 1600, but they took tons of work in post to make useable (and I wouldn't want to print them too big....)

So, while for a landscape photog (which I'm guessing you probably are, given your talk of ND filters and uwa lenses) high ISO might not be a big deal, for many who are shooting theater, concerts, weddings in dark churches, poorly-lit sports etc... it's a lifesaver. And while the 5d2 is awesome, it's expensive, and not everybody can throw that kind of money at a camera. Also, the extra reach on a crop camera is great for many situations, so I'm thrilled they've released a 1.6 with some higher-end features! I'm very much looking forward to seeing how the 7d performs in reviews and real life use once it hits the streets.

No kidding.

I had given some consideration to the 5D MKII for it's clean high iso output, but it's price (and the fact that my lenses are tailored for a 1.6x sensor) made it just unattractive enough for me to take that leap. The 7D on the other hand seems to fit the bill for my needs, that is if it lives up to it's hype.

Exactly! I can get a 7D and a 70-200 f/4L IS for just a little bit more than a 5D MK II by itself. :D

I'm this close to ordering one <pinches thumb and forefinger together> but I'm still waiting on a verdict as to whether it's a worthwhile 40d upgrade.

I hope everything on this list pans out, this is the list I compiled compared to the 50D, but most apply here as well!

- more af modes, including spot mode that constraints AF inside the AF box
- supposedly better AF
- 19 AF points
- better sealing
- wider angle onboard flash
- 3 custom setting modes (3 on the 40D, 2 on the 50D)
- over 30% faster fps
- new longer battery life
- 3 larger raw sizes
- more resolution
- better high ISO performance (native 6400, ISO 50/12800 expansion)
- movie mode (with improvements over other models that have this)
- multi functional button
- longer shutter life
- 5% larger viewfinder
- lcd overlay focus screen
- electronic level and roll indicators
- wireless ETTL flash control
- color spectrum metering w/63 zones
- dual digic IV
- better overall lcd viewing
- removal of the noob modes
- RC1 IR remote control support
- Auto ISO works with ISO 100-3200

You realize it has the same level of weather "sealing" as the 5DmkII, right? Which is to say, it's better, but it's no 1D in that regard.

If that is the case, then why does dpreview list the 5D2 as being almost as well sealed as the EOS 1n, and the 7D as being sealed as good as the EOS 1n?
