I'm rather new at all of this. What would be the issue of "normalizing" all of the comparison cameras to the 7D, rather than the other way around?
The truth, but reviewers don't get paid to provide that.
To understand these tests, I first imagine applying appropriate chroma NR AT FULL RESOLUTION, and then downsizing, or more usefully uprezzing them all to 18 or 21 Mpixels. I don't agree that the 5D2 produces no more than 12 Mpixels of data at iso 3200. Noise is data, and correcting it in software can be done much better at 21 Mpixels than at 12.
From this test I intuit (I have to, since the reviewer has obfuscated important data) that the 5D2 is the best performer at iso 3200. It will benefit greatly from chroma NR at 21 Mpixel resolution and will overtake the D700, which has already been NR'ed by the camera. It is hard to say whether the D700 or 7D will be better once the typical process has been applied instead of this. The D5000 certainly comes last. You have to imagine the effects of chroma NR at higher resolutions to see the truth behind this test. That's hard to do without a lot of experience, and even then...

Will the new SanDisk Extreme Pro 90MB/s CF cards help the speed of the 7D at all? Or are we looking at future cameras only being able to take advantage?
The 7D will support UDMA mode 6, and Canon has stated that we can expect a little bit improved performance with those new cards. The source of this information is the technical details from an official Canon ad, I just can't find the link right now, but it should be in this thread.

This is from the US brochure:
Professional Level Performance
Capable of shooting up to 126 Large/JPEGs with a UDMA CF
card at 8.0 fps, the EOS 7D is a perfect camera for action.
The EOS 7D is outfitted with a rugged, remarkable shutter, which, aided by
the Dual DIGIC 4 Image Processors, ensures instant response and performance
on par with most professional cameras on the market while outpacing

Here's a little example of what I'm talking about, just using the above sample and applying dust and scratches in photoshop:
Of course, the Canon files can do better because I have had to apply dust and scratches at 12 Mpixels instead of 18 and 21....Show more →
Thanks for sharing this tip. Very useful info and great post.
"Memory card choices
The Dual "DIGIC 4" processors ensure a level of future proofing for the camera by allowing the use of Mode 6 UDMA Compact Flash cards. Although Mode 6 UDMA crads are not currently available, it is expected that they will appear later in 2009. When this happens, it is possible the maximum burst capability of the camera will improve."

Thanks... I had not seen that. We will all be loaded for bear with a new card and the 7D...

If the new AF can effectively execute with that kind of throughput in appropriate shooting circumstances we will have a real winner in our hands!
That's the only potential remaining question mark for me. Time will tell.
What's interesting about this conversation is that much of the focus so far, on a "sports/action" camera has been on low light. I guess that's because of the availability of high ISO low light shots.
I'm with Cameron, I'd like to hear more about the AF. So for those of you who have earned a spot on early releases, please more on the AF. I'm fairly well convinced that this is my next step in the APS-c realm. Very glad they did this before the 60D or I would have been one of those who jumped on that bandwagon, only to be disappointed when the 7D came out.

True, and annoying, but that's the way it is.... That price includes an 8GB Extreme 1V and a spare battery, at least at the vendor I'm using, so that helps a bit.

It's not a sports camera for me - it's a general purpose camera. And about the high ISO interest... Well, basically all DSLRs produce good quality low ISO images, hence the interest in high ISO - that's were the difference shows.

Please brainiac, enlighten me: in US, the price of 7D will be 1700 USD. Including the shipping, the price goes to 1800 USD (almost 1100 GBP).
If you have to pay VAT on imported goods, you'll have to pay another 15% (17,5% starting Jan 1st 2010). All sums up to 1265 GBP. Let's make a round number: 1300GBP.

What's keeping you from doing this ?
In France (and likely UK as well), there is a warranty problem with buying Canon bodies in the US (not the lenses though). Here in France to lowest price I could find for the 7D is 1600€ (including taxes).
Add me to the pre-order club as I’ve placed an order with Adorama.
I haven’t gone through all the posts on this thread but it looks like most folks are concerned with high ISO noise, but from what I can see it will suit my needs just fine.
What I'm interested most is its AF ability. I’ve never shot a 1 series body, only shooting xxD bodies, but the AF options look mighty nice. I think I’m gonna like - spot AF, AF point expansion, AF zone selection, and servo tracking sensitivity.
Hopefully I’m not too far down the pre-order list.
Here's a question from a non-Canon user:
I've been going through the user manual for the 7D, and it seems to me that the only way to check what metering mode the camera is in, is by looking at the top LCD. Have I misunderstood something, or...?
