Paul, The metering's definitely better on the K-7, but everything I'm seeing is showing noise performance to be similar to the K20D given the same scene and exposure, the net win is entirely from the better metering and thus disappears when you stop relying on AE, which I do in really low light. When I bought the E-30, I looked closely at the K-7 (it was fundamentally the camera I wanted), but I saw little difference in the actual high ISO performance between it anc the E-30, maybe a half stop at most (the K-7 is better at 3200 than the E-30, but 6400 on the K-7 is definitely worse than 3200 on the E-30). The K-x on the other hand is damned near clean at ISO 6400 and remarkably good at 12,800. I'd rate it almost 2 stops better than the K-7 for noise. Note I pretty much end up ignoring the meter in really low light, I work from the histogram instead and reshoot if necessary. And that's how I've worked with all my digital cameras (including the Nikons which have better metering than the K-7). If I really have to meter at high ISO, I use the spot meter. -- M.
