|Although the Canon EOS 1000D is an entry-level model, it offers enhanced setting possibilities. Canon chose not to dress down the camera as much as possible, but just enough to make the difference in the specifications of the 450D and the EOS 1000D. Whether Canon succeed, depends mostly on how the sales price is keeping in practice. There are differences in image quality, although they are marginal, and technical tests carried out in the DIWA lab show that the Canon 1000D is not a 1 to 1 copy of the EOS 450D when it comes to image quality. |
|Canon EOS 1000D colour reproduction
As far as colour reproduction is concerned, the Canon 1000D hardly differs from that of the EOS 450D. Whereas the EOS 450D shows a straight, slightly descending curve over the 100-1600 ISO sensitivity, the Canon EOS 1000D shows a somewhat deviating curve for 400 and 800 ISO. This measurement however, is not visible in practice with the naked eye. The colour reproduction of the camera is accurate and consistent which is an excellent result.
Automatic white balance at incandescent light
As for white balance, Canon has absolutely no trouble in general to carry out an accurate measurement, however, the auto white balance gets it wrong rather frequently at incandescent light. It is advisable to set a manual white balance in situations with difficult incandescent or fluorescent circumstances. The results then turn out to be extremely precise and quite consistent over the entire range. The dynamic range of the Canon EOS 1000D is superb. Although slightly less consistent, the Canon 1000D scores highly up to and including ISO 400 and flattens somewhat from 800 to 1600 ISO with fine as end result. Details remain visible throughout the entire ISO sensitivity range and don't bleach light areas in the picture too easily.
Sensitivity of the image sensor is also measured in the DIWA Lab. The differences between the sensors of the EOS 450D and the Canon EOS 1000D are clearly visible. With a difference of 18-28% of actual sensitivity and the claimed sensitivity, the EOS 1000D shows the difference between the sensor characteristics of the 450D and 1000D. To put it differently; 100 ISO is actually 85 ISO and 1600 ISO actually reduces to over 1200 ISO. If we compare this with the 450D we see a similar difference for 100 and 200 ISO, but at 400 up to and including 1600 ISO the claimed ISO sensitivities are at pace with the measured sensitivities. It won't hurt to overexpose with 1/3 - 2/3 stops with the Canon EOS 1000D.
|Signal / noise ratio
One item on which Canon scores highly is the signal/noise ratio. Although the competition tries, Canon is still leader in controlling the noise issues, and this is one of Canon's most important feat of arms. And indeed, the tests in practice together with the technical DIWA Lab tests show that up to and including 400 ISO it is no problem to take pictures which are good for A3+ enlargements. At ISO 800 the first sign of noise shows, however, marginal and up to 1600 ISO everything is under control. Two exceptions are the red and blue channels that deviate a little. These are the channels that sooner show noise in comparison with the 450D.
Canon 1000D kit with EF-S 18-55mm lens
Our Canon EOS 1000D test sample comes with an EF-S 18-55mm f/3.5-5.6 IS lens. This kit lens has an onboard stabilizer and an average range. If we check the sharpness in the centre at 18mm, we find an excellent result, a beautiful sharpness also at 25mm. In telephoto mode, blur starts from f/32. At 18mm wide angle and f/3.5 some blur is visible towards the edges although still under control. At 25mm blur is also visible at a large opening, however, zooming in two stops makes it right again and the sharpness is then completely fine. The same goes for the telephoto area. Blur at the edges appears visible only at f/22 - f/32. An excellent performance on sharpness.
Aperture range & Chromatic aberration
Distortion at 18mm is reasonable and only slightly visible over the entire aperture range. The remaining focal lengths hardly suffer from any visible distortion. The thing wide angle range suffers from tremendously is chromatic aberration. In particular up to and including f/8 it is rather obvious, after that it decreases to a reasonable level. If you take a picture with maximum opening and f/3.5 chances are high you will get vignetting visible in your picture due to this lens. The dark edges will certainly appear in blue skies. If you want to make sure to prevent this phenomenon from occurring, you should use a lens hood with an aperture to f/5.6 for an optimum result. The lens performs reasonably to fine as a kit lens. It's silly to expect or demand more from a cheap lens like this; a 'perfect' lens happens to cost a lot more!
