My informal tests comparing the new Panasonic ZS100 (1-inch sensor) to the Leica X-U (APS-C), both using 35 mm effective focal lengths, except the final image where the ZS100 zooms to its maximum of 250 mm eff. focal length. The amazing thing in the harbor set, in dull flat lighting, is that the Leica X wins clearly on the water tower and the ocean water, but the ZS100 wins big on the trees detail, unless I'm missing something. These were shot JPEG only. In the statue scene, the X-U has some wins and some ties, but I don't see a win for the ZS100. The ZS100 zoomed scene shows the camera's strength. The ZS100 lens does seem to be good edge to edge, at least at the apertures I shot, which I would expect for a $700 USD camera. The processing here was a 2 pct. crop on the ZS100 images, and all were resized to 4096 pixels wide. I also sharpened the ZS100 images slightly. Another bit of fantastic news, for me anyway, is the carrycase: The Leica 18727 case made for the D-Lux6/Panasonic LX7 fits the following cameras precisely, like a glove: Panasonic ZS100. Panasonic LX7. Leica D-Lux6. Nikon Coolpix A. The similar case made for the Leica D-Lux/Panasonic LX100 also fits the ZS100 well, with a mm or two extra room in length and width.
