Canon 40D vs Nikon D300

What a difficult choice—both leaders just released excellent prosumer models. Both dSLRs offer top-notch features like self-cleaning sensor units and low-noise CMOS sensors, the latter being exclusive Canon selling point for several years. But how do they compare now in key characteristics, after Nikon catched up with the competition?

For pixel peepers, neither of those are interesting—the real winner is Pentax K10D, which has very light anti-alias filter and offers the best per-pixel sharpness and unique non-processed, completely photographic 3D look—check out some examples. At about $700, with image stabilisation built in, this camera can become a great choice for photography geeks—imagine its potential after processing photos with DxO Optics v5.
