At 100 ISO the picture is clean, well detailed and noise free, everything we’ve come to expect from a Canon DSLR. Lenses – Should have no marks on the elements andoptically clear. There may be light dust present that will not effect theimagery. Again, the 35-zone evaluative metering system has coped with this unusual shot, capturing both shadow and highlight detail. In terms of performance, the EOS 400D is everything we’ve come to expect from a Canon DSLR. It starts up virtually instantly, and in continuous shooting in fine JPEG quality mode it can rattle off 21 shots at an impressive 2.5 frames per second before it has to pause to write data to the memory card. Even then, the progressive buffer means you don’t have to wait until it’s finished processing every frame before you can shoot again. Even in RAW plus fine JPEG it can shoot at the same speed, although this time the buffer can hold only eight shots, and you have to wait a little longer before shooting again. One slight annoyance, which was also present on the 300D and 350D: if you open the card hatch the camera shuts down immediately, and any images still waiting in the buffer are lost, so make sure you have enough room on your card before you start shooting.

The most obvious internal improvement is the CMOS sensor, which is increased in resolution to 10.1 megapixels and now includes an automatic cleaning system, which uses a combination of an anti-static coating on the anti-aliasing filter, ultrasonic vibration and pixel mapping to ensure that dust on the sensor is less of a problem. Battery Life: Excellent. On my first charge (which means a lot of playing and less shooting) the meter dropped to 2/3 at 575 shots. It dropped to 1/3 at 980 shots, two weeks later. Three weeks later it died at 1,122 shots. On the next charge I got 824 shots before it dropped to 2/3. I’ve taken this same shot under virtually identical lighting conditions with a range of 10MP DSLRs, so you can get an accurate picture of how they compare. Enjoy fast Auto Focus and full resolution shooting at 3.0 fps - just point and shoot for impressive results with Scene Intelligent AutoIt's nice, but I prefer my Nikon D40, which costs less. I prefer cameras based on their usability. The XTi probably has more real resolution if you print everything at 20x30" (50 x 75 cm), but I rarely print bigger than 12 x 18" (30 x 40 cm). If you're the kind of guy who uses a tripod in broad daylight consider the XTi, and if you're someone like me who hand-holds and uses fill-flash, the D40 is much better. If you're starting out and undecided as to brand, I'd opt for the Canon Rebel XTi over the Sony A100, but personally I prefer my Nikon D40 to any of these, and it costs less! I own all of the Nikon D40, D70, D80 and D200 and Canon Rebel XTi and 5D. See the world through the optical viewfinder and instantly review results on the user-friendly, 6.8 cm (2.7”) LCD screen At the maximum 1600 ISO there is some visible image noise over dark and mid-tone areas, but the image quality is still good enough to print.

The viewfinder is also somewhat improved, with a nine-point focus indicator and a bright green LED information display. It seems larger and brighter than the 350D, and is about the same as the viewfinder on the Sony A100 and significantly larger than that of the Olympus E-400. Cameras – LCD screen is heavily worn either by de-lamination or has scratches to it. Rubber grips are starting to come away from the body. I like this little camera! It's lightweight, it's intelligently designed, it works well and can make extraordinary images. Its LCD is worlds better than the disgusting greenish LCDs on the 30D and my 5D. The high dynamic range of the Canon CMOS sensor and the excellent metering system make light work of this high-contrast shot.It comes as a body only, or as a kit with the excellent and inexpensive EF-S 18-55mm f/3.5-5.6 zoom lens.

The 400D uses the same highly acclaimed Digic II image processing engine as the 350D, but is now equipped with a nine-point AF system, a much wider range of features and a vastly improved control interface. The 400D offers a huge range of picture adjustment and control, but at the same time manages to be accessible and easy to use. The key element is the Picture Style option. There are nine pre-set Picture Style settings, all of which can be customised for sharpness, contrast, saturation and colour tone, with nine increments of adjustment for each parameter. The default settings are for standard, portrait (less sharpness) landscape (extra sharpness), neutral, faithful and three user-defined settings. When shooting, these Picture Style settings can be selected by simply pressing the Set button and scrolling up or down on the D-pad. It make accurate professional picture quality control very easy. Thankfully the annoying feature of the 300D and 350D, where menu choices had to be confirmed by pressing the Set button has been dropped. Experience the power of interchangeable lenses.
