Judge for yourself by plugging in the 7D to one of the boxes and moving the zoom around the scene, especially dark areas. Then scroll down the page to see how much shadow lifting has improved over the 18MP sensors. Other than that, the 7D seems better suited for dedicated birding than the 70D, when you factor FPS, build, and AF options.

When pushing dark shadows hard, I've found the 60D to be visibly better than the 7D, but obviously the 7D is a massively better camera for fast moving subjects. How the 70D compares I don't know, but I can tell you that the 7D is pretty decent (as long as you don't need to lift shadows too much).

Got it. Same boat here. Should start a pool on anticipated arrival...since I've got a big trip starting Sept 19th I'll wager deliveries will begin on the 20th

FWIW, I ordered the T2i from B&H when they first accepted pre-orders. I received the T2i on the day they were allowed to start selling it. I did not pay for overnight shipping, so they must have estimated the shipping time and shipped accordingly.

Do the 70D raws have better IQ than a 7D? I'm about to buy a 7D (dedicated birding body), but I'd consider the 70D if the IQ is superior.

I just explored the preview shots and it seems as though the 70D does not represent a change in IQ performance at high ISO. It is premature to judge the camera on a pre-production model, but I doubt Canon sent out pre-production models that would make their final product look bad.

If this holds true, then the appeal of the 70d is limited to a significant feature-set upgrade rather than an IQ boost over the 18mp sensor cameras.

Looking at the dpreview samples I think it's clear that the 70D is slightly superior to the 7D at High ISO. But it still lags behind the Nikon 7100.

That's what it looks like. This new sensor is not the answer to the Exmore, that is clear. The raw files show pretty clearly that the sensor performs about the same as the 7D, maybe a tad worse. So it's in the feature set of the camera where the improvements have been made. The dual pixel thing could be a very strong draw to videographers. For still shooters, there is not much.

really? I saw the opposite unless your comparing in camera processed jpegs.

Maybe stop worrying about specs when you might not know how your photography style and needs will be suited with them. It would be wise to buy something cheap now (Rebel, 60D), learn what you like and don't like, and then dig into spec sheets and tests to see what you want to upgrade to. Buying a 70D when it comes out will be fine, but it may or may not be far more camera than you end up needing.

If I ever decided to buy an F1 race car, I would have to learn how to drive even a low-end one first just to get any idea of what is good and what I need for getting groceries as fast as possible.

Ok.... So I know who sucks at analogies. And assumptions.

Contrast detection is essentially sampling pixels off the sensor, and moving the focus around to try to maximise the contrast - the thinking being: more contrast == better focus. If I understand correctly, it's actually very accurate (more so than phase) but the camera has to hunt, because it doesn't know in which direction the focus is off (so it's a bit slow).

Phase detection is where the image is split, and an AF sensor detects the phase difference; which allows it to see in which direction (and by how much) the focus is off. It's fast, but can be a bit less accurate, and is also prone to problems (the distance from the optics to the AF sensor must be exactly the same as the distance from the optics to the imaging sensor). The dual pixel AF system is effectively doing a form of phase detection using the pixels on the sensor - i.e. fast AF in Liveview, and should be 'perfect' focus.

Sploo, thanks, that clearing it up. I hope you weren't typing that with a fast phone.

the jpg's look better than the 7D...i only shoot raw about 25% of the time right now, and the majority of that, is when i'm tripod mounted so i'm not neccesarily at the highest ISO...so i think this will probably be my next camera...unless of course the 7D II is announced before end of year

Bold my emphasis:

I am surprised by this. You can always get the same/better jpg from a raw file, and often save an image using the raw data compared to what was output as jpg (e.g. overexposed areas), where the jpg itself is beyond saving.

I've been shooting raw since the first DSLR I got, since it seemed easy enough to process them, and it seemed better to start off with the best data possible, even if my final jpg looks not much different from the one SOOC.

Do you prefer to shoot jpg for space reasons (more images on the card), or simply because you find you don't need to push the raw image around much and the jpg is already suitable?

Huh? Sorry if you think I was trying to be condescending or whatever it is that you were offended by. I was giving reasonable advice to someone who says quite clearly that they are a "semi-noob", and even left it open ended at the possibility that the 70D might not be good enough for your skill level. Thanks for being condescending yourself, though.

BTW, I also suck at many other things including photography, if that makes you feel better. The 70D has way more features than I could ever learn to use.

It is disappointing that the sensor isn't improved. It is not that i think the 18mp is bad or anything but I was hoping to maybe upgrade and see those improvements that sony/nikon got a few years ago

If you do a comparison at 12,800 you can see more noise on the 7D...

Hmm.. I'm not seeing a difference. They both look like sh!#.

I see a little more green chroma noise in the 7D, but yeah, they both look unusable to me too.

I wonder... What the heck is Fuji doing with their sensors! Their Prox1 is nipping at the heals of even the mighty 6D for high ISO performance. I don't see much detail loss either. REMARKABLE! Screw Nikon's benchmark, Canon should be aiming for Fuji.

Anyone have ideas as to what's going on with the Fuji sensor and why it looks so clean and detailed?

What's this ISO button do again?
