To measure and compare the Panasonic Lumix TZ1's
geometric distortion we photographed a test chart consisting of a grid pattern,
using it and a number of rival models.
Here are the results for each camera with their built-in lenses at their
widest focal length; where possible, the aperture was closed.
The images were analysed with Imatest using 5th Order line calculation and
the full areas presented here at a reduced resolution.
The image left was taken with the Panasonic Lumix TZ1 zoomed-out to 5.2mm.
