Canon EOS 40DCanon EOS 40D Review,Phil Askey, October 2007

Review based on a production Canon EOS 40DThe EOS 40D becomes the sixth Canon prosumer digital SLR, a line which started back in 2000 with the EOS D30, and how far weve come. Its been eighteen months since the EOS 30D and although on the surface the 40D looks like a fairly subtle upgrade theres a lot that makes this an even better camera. Of course we expect a step up in megapixels, and so the 40D comes with a ten million pixel CMOS sensor with the same sort of dust reduction as the EOS 400D, an ultrasonic platform which shakes the low pass filter. Other improvements bring the EOS 40D closer into line with the EOS-1D series, these include a move to the same page-by-page menu system, both RAW and sRAW (2.5 MP), 14-bit A/D converter and 14-bit RAW, cross-type AF points for F5.6 or faster lenses, a larger and brighter viewfinder, interchangeable focusing screens, a larger LCD monitor (3.0") and faster continuous shooting (6.5 fps).Model line historyModelAnnouncedEffective pixelsAuto focusContinuous (JPEG)LCD monitor
