On top of all that image quality is simply superb, great resolution, low noise and the excellent color response that we've come to expect from Canon Digital SLR.

Despite its size and weight, the camera handles beautifully, with every control both easy and intuitive to operate.

What People Are Saying Give it to me straight


What's amazing is that this leap in resolution and pixel count has been produced almost effortlessly*, Canon have simply delivered far more than we had expected by the end of 2002.

If the thumbnails selected are RAW images you can also adjust RAW parameters either individually or as a group (see more below).
by DPReview (Dec, 2002)
This is a worthwhile comparison as it will give us some impression of the improvement in resolution we can expect moving up from six to eleven megapixels.
by DPReview (Dec, 2002)


In playback mode the default display is 'single image', each of the other displays can be selected in play mode (press the DISPLAY button) by holding the DISPLAY button and rotating the main dial.
by DPReview (Dec, 2002)
Images have been reduced down to fit into 800 x 800 bounds to fit onto your screen, as always the original untouched image is available by simply clicking on this reduced image (original images are approx 4.0 MB each - please treat our bandwidth with respect).
by DPReview (Dec, 2002)
Just like the top LCD this LCD is backlit by blue LED's which can be turned on by pressing the backlight button on the top of the camera.

Having 45 focusing points isn't just about being able to choose your focus area within the image it also means that focus tracking (AI Servo) can be much more effective (as the subject is more likely to be picked up by at least one AF point).
by DPReview (Dec, 2002)
In automatic AF point selection mode the camera will highlight (glowing red) the AF points which were used to measure AF distance.
by DPReview (Dec, 2002)
The diagram on the left, above shows how these areas equate to the portions of the viewfinder view and AF points, in AF point-linked spot metering mode one meter zone serves several AF points.

At this stage in the review I had wanted to compare the EOS-1Ds with the other 'big megapixel' Photokina 2002 announcement, the fourteen megapixel Kodak DCS-14n.
by DPReview (Dec, 2002)
The four megapixel EOS-1D is the fastest shooting digital SLR currently available, with an amazing eight frames per second continuous drive mode it's clearly aimed at the news and spots photo journalist.
by DPReview (Dec, 2002)
The EOS-1D has a 4 megapixel sensor and can capture at an amazing 8 frames per second, clearly targeted at the sports photographer.
by DPReview (Dec, 2002)


It is most noticeable at wide angle and maximum aperture and will vary depending on the lens.
by DPReview (Dec, 2002)
This means that the 1Ds is more likely to reproduce lens effects which are normally to be found near the edges of the lens, such as chromatic aberrations.
by DPReview (Dec, 2002)
The ability to use 35 mm lenses at their designed focal length (field of view) combined with the high pixel count will be strong points for those film photographers who have hesitated on going the digital route because of these two issues.
