To measure and compare the Panasonic Lumix TZ1's lens vignetting and light fall-off we photographed a white target with a highly diffused custom filter using it and a number of rival models.

Here are the results for each camera with their built-in lenses set to their widest focal lengths with the apertures wide open and the focus set to infinity.

The images were analysed with Imatest and the full areas presented here at a reduced resolution. Bigger percentages are better.

The image left was taken with the Panasonic Lumix TZ1 zoomed-out to 5.2mm with its aperture wide open.

To measure and compare the Panasonic Lumix TZ1's lens vignetting and light fall-off we photographed a white target with a highly diffused custom filter using it and a number of rival models.

Here are the results for each camera with their built-in lenses set to their longest focal lengths with the apertures wide open and the focus set to infinity.

The images were analysed with Imatest and the full areas presented here at a reduced resolution. Bigger percentages are better.

The image left was taken with the Panasonic Lumix TZ1 zoomed-in to 52mm with its aperture wide open.

Here the light falls off in the corners to an average of 81.8% of the center measurement, which again is similar to some compacts, but not as good as the better models out there. As above though, it's still sufficiently low for you to hardly notice any darkening in the corners of telephoto shots.
