Seven years since the EOS D30, the sixth incarnation of that camera displays all of the advantages of a progressive evolution in both features and quality. With each step up the evolutionary ladder to the EOS 40D Canon has demonstrated improvements in...
Abstract: The new Canon EOS 40D, announced by Canon on August 19th 2007, is the latest addition to Canons line of "prosumer" cameras and replaced the Canon EOS 30D. While the EOS 30D was a minor upgrade of the EOS 20D, the new Canon EOS 40D is a whole new camera, w...

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...

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...
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 400D are both more suitable options for amateurs, the 40Ds bl...
Generally superior shooting speed among dSLRs, First-rate photo quality
Large spot size for spot meter, Relatively sluggish low-light focus
Great photo quality and excellent continuous-shooting performance are just two of the Canon EOS 40Ds many attractions in the digital camera marketplace. ...
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...
