Panasonic G1, 45-200. One interesting note - all of the trouble I was having with the G1 not focusing, or focusing incorrectly, was resolved instantly by an expert photographer at an Ohio photo (not camera) club last month. That person removed the lens and wiped the contacts on the lens and camera with their finger - problem solved. Since nobody on LLVJ thought of that, despite extensive discussion of same, it makes me wonder -- how many users here would benefit in their photographic experience if they just cleaned a few electronic contacts now and then? Scary, isn't it?
