철' 사진 속으로..: Oh my god!! 40D

드디어 나의 30D후속 40D 등장

Canon EOS 40D Preview
Phil Askey, August 2007

The EOS 40D becomes the sixth Canon 'prosumer' digital SLR, a line which started back in 2000 with the EOS D30, and how far we've come. It's been eighteen months since the EOS 30D and although on the surface the 40D looks like a fairly subtle upgrade there's 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).

UPDATE 25/Aug/07: We have just added a gallery of sample images from a pre-production EOS 40D.

Preview Notes

This preview is based on material supplied by Canon, it is designed to provide as much detail as we can about the EOS 40D at this point in time. As soon as we are able to produce a hands-on preview or review of the camera we will replace this article.

Dpreview use calibrated monitors at the PC normal gamma 2.2, this means that on our monitors we can make out the difference between all of the grayscale blocks below. We recommend to make the most of this review you should be able to see the difference (at least) between X,Y and Z and ideally also A, B and C.
