Pentax K200D (RAW) vs. Canon EOS 450D (RAW)
Canon EOS 450D
2.8 MB JPEG (3872 x 2592)
3.6 MB JPEG (4272 x 2848)
While the Canon JPEG images are clearly better than their Pentax counterparts, when shooting in RAW there is hardly any difference. Thanks to its slightly higher sensor resolution the EOS 450D still delivers a tiny extra amount of detail. On the edges of the frame the K200D is also being let down a little by the Pentax lens.
