To measure and compare the Panasonic Lumix LX2’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.

To measure and compare the Panasonic Lumix LX2’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 above was taken with the Panasonic Lumix LX2 zoomed-in to 25.2mm with its aperture wide open. Set to a 16:9 aspect ratio as pictured, the light falls off in the corners to an average of 84% of the center measurement. For comparative purposes, we repeated the test in 4:3 mode which delivered a better result of 89.7% by avoiding the extremities of the lens. On this level playing-field, the LX2 matches the best of the cameras below, and even when recording a much wider frame still manages to beat some models.
