Looks like we have something finally to compete with the D300/D700/D3 from Nikon.
Considering the 5D MKIIs shot comings in terms of all roundness (for lack of word) esp. in terms of Speed and Hopefully focus and Dynamic Range ( if making it 18Mp helps with dynamic range.)

Hope it’s true.

It's a crop. I see Canon isn't listening. 18 mpixels. The other specs are quite impressive, imo.

Yer Canons Fastest Pro Sports Action bodys are Crop but its x1.3. like in the 1D MkIII, 10 FPS. (think thats the right model.)

Thats the Canon with the best auto focus, much better and faster then the 5D MkII focus.
Hopefully the 7D will have that foucs system.
Problem is you either have good focus and speed of the 1d mkIII ( or 7D maybe) or the full frame glory of the 5D MkII you cant have both like the Nikons do.

It says APS-C, not FF, wtf? Hard to belive this.

Who knows, I think cropped and down to 18MP to get the speed.

Something in between the 50D and this new 7D seems likely.

a 50D with video ... and may be a few more MP as a free bonus.

Canon 7D upgraded from a Canon 40D + Canon 24 -105 L is + Canon 100 - 400 L is + Canon EF-S 10 -22 mm + Canon EF-S 60 mm macro + Canon 135 L + flash 580EX - my web site  (external link), Zenfolio (external link)- and also on Flickr (external link). :)

What was the point of stuffing 18MP on an APS-C sensor and making it produce big, noisy, blurry files from lenses not designed for such a high pixel density, with no more detail actually resolved than with a 10MP sensor and becoming diffraction limited at f/6-7?

Could they not instead have given us an 8-10MP sensor with much better dynamic range, ISO 6400-12800 with well-controlled noise and capable of shooting 16fps (9MP shooting at 16FPS would have the same amount of data moved as 18MP at 8fps)? Surely the pro/prosumer market (particularly wildlife photographers) that this body is presumably aimed at understand that megapixels aren't everything...

If this is true, it's a real disappointment, given that Canon recently reduced the pixel density on the G11 as compared with the G10...

They have of course a new, fantastic sensor technology which gives ultra-crisp images with all these pixels. You are just pessimistic! :eek:

Nothing to do with the sensor - it's just optics. On a 1.6x crop factor Bayer-interpolated sensor, an image shot at f/8 will become diffraction-limited at 11MP (Airy disk the diameter of two pixel widths), while an image shot at f/11 (very common for landscapes) will become diffraction-limited at just 5.9MP - any more megapixels will not be adding to image detail, regardless of lens quality, but will merely contribute to image size and noise.

The noise and file size drawbacks could be there, of course. It was the noise thing I somewhat humoristically referred to above.

But apart from that, there's nothing negative with more resolution. When you do open up, so that diffraction doesn't have much of an impact, it can deliver more than a 6 Mpix camera can.

Rest assured, the engineers at Canon are smarter than you. Let's see what they really announce tonight before hanging them.

Shadowblade: yep, it's true. I thought that mindless pixel race is over looking on specs of new g11 but sadly it looks like this does not relate to DSLRs....

Marketing trumps engineering any day.

18MP is easy to sell. 10MP with improved DR, faster shooting, better noise, etc. is much harder.
