Abstract: Canon EOS 40DPerformance Review and Microscope Application The following images and data are from initial performance evaluation on the Canon EOS 40D for general photography and photomicroscopy. I was most interested in the 40D's performance (resolutio...
Abstract: This 10-megapixel digital single-lens reflex has several evolutionary improvements over the EOS 30D, including the extra 2 million pixels, a larger LCD screen and what is called "live view" function. Live view is using the LCD screen as the view...
The picture quality from the CMOS sensor and image processor is smooth, film-like and noise free even at high ISO settings. Dynamic range is as good as it gets, with detail well preserved both in highlights and shadows. The mechanical refinement of the...
The larger LCD is a low resolution affair, with 230,000 pixels, compared with nearly one million on the Nikon D300 and the Sony A700. This diminishes the usefulness of live view and also affects picture review. And there is no auto-focus assist lamp fo...
This is a fine camera with worthwhile advances on its predecessor. Canon has dominated this segment of the market for DSLRs between $2000 and $3000, but now faces stiff competition. The Sony A700, the Nikon D300 and the Olympus E-3 are coming soon, whi...
Some minor auto focus problems in low light The Final Word For at least a little while it appears the Canon 40D is king of the hill. While the Nikon D80 and D200 both provide reasonable alternatives for enthusiasts, and the Nikon D40x and Canon EOS 400...

Abstract: A replacement for Canons EOS 30D has been due for some time so the unveiling of the 10.1-megapixel EOS 40D at the end of August was no surprise. Nor was the inclusion of Canons EOS Integrated Cleaning System, which was pioneered on the EOS 400D and i...
Feature-rich, 3-inch LCD screen and Live View, Good tonal response, Good battery life
Focusing manually using Live View can be a pain
The Canon EOS 40D is a subtle improvement over the 30D, but in many ways it’s also an understudy for the EOS 1D Mark III. The 40D is used by many professionals as well as enthusiasts, and in our tests we found the camera does have a lot to offer...
A set of useful new features; retains the user-friendly design of its predecessors; good-value-for-money kit; class-leading build quality and continuous shooting speed.
