Nikon D90 (RAW) vs. Canon 450D (RAW)

Nikon D90
Canon 450D
2.9 MB JPEG (4288 x 2848)
3.7 MB JPEG (4272 x 2848)

Having seen how much sharper the RAW results are than the default JPEG output, it comes as no surprise to find that the difference between the 450D and the D90 evaporates when processed in the same manner. We have always suspected that the 450D has quite a light anti-aliasing filter and this is supported by looking at the medals on the third crop - there is a smidgen more detail than the D90. But think back to the JPEG and there was also a hint of color moiré (the frequency of the pattern on the bottle interfering with the spacial frequency of the photosites on the sensor - precisely what an AA filter aims to reduce). And that appears to be the only difference.
