Need education as to Image Quality

I spoke with tech support this AM on a side matter but we got to talking about the IQ of the new 1DX.
She said the image quality and crop ability was better than my 1Ds MkIII...how can 18 MP crop as well/much as 21 MP, assuming <1000 ISO?

I guess IQ and crop ability could be better with the 1DX over the 1Ds Mark III even though it has less MP's. I'm guessing if the IQ is better on the 1DX you will be able to crop more because the image is clearer then the image you get with the 1Ds Mark III. I guess we will just have to wait and see how the 1DX will be when it gets here.

Take Care,
Cheers, Patrick

To quote the folks at DPReview:

"The biggest specification change to the 1D X is its new sensor - an 18MP full-frame CMOS chip capable of shooting at 12 frames per second. This represents a big change over the 1D Mk IV (it represents a move away from the smaller APS-H format that Canon has previously used in its sports cameras), and a decrease in pixel count compared to the 1DS series. However, as Rick Berk, Technical Specialist in Canon USA's Pro Engineering and Solutions Division says: 'there's more to image quality than just resolution.'

The move from APS-H up to full-frame is enabled by a sensor with faster data readout explains Chuck Westfall, Technical Advisor in Canon USA's Pro Engineering and Solutions Division: 'The new sensor has 16-channel, dual line readout, compared to 8-channel, single line designs in the previous generation of chips.' This lets the company offer a large sensor (and the low-light capability that brings) for 1DS users, with the fast capture speeds that current 1D Mk IV users need. 'It's clear the time has come for the 1DX to replace the whole 1D series,' says Westfall.

Under the skin, the big change is the more sophisticated metering sensor. A move from the 1D Mk IV's sensor to a new 100,000 pixel unit affords the camera a much better understanding of the scene and this information is fed into the camera's autofocus system to improve the quality of its AF tracking. This isn't a new idea (Nikon's sports cameras have done something similar for several generations), but it's a sensible way of improving what's already an impressive system.

CaptB...any chance of getting a link to your information...would like to read the whole thing.

I think that my 1d mkIV crops better than my 7d did.

Here you go.

Where's the BS smiley when you need it ?

But then and again, maybe she likes BIGGER pixels ? ? ? I've got an old 1.6 MP digital from way back when- maybe she will like that - it's got real BIG pixels.
