How does the LX5 compare with the X10?
LX5 is a great camera, and rivals with the S95 back then (well, it wasn't that long ago, but still...) These two cameras each have their strengths, though I do recall that some people complain about the bigger lens of the LX5 making it too big to fit into the shirt pocket.
As for comparing the LX5 with X10, I would suspect that Fuji's product probably capitalizes on the generation difference between it and the LX5.
(Though I don't think it's fair to compare the S95/LX5 with the X10, since the X10 is more of the level of advanced compact - like G12 and so. Panasonic doesn't have something in that category - maybe GF3, but that's EVIL, not a compact).
