I just like the image quality I get from the L1. Of course the lenses has something to do with this as well as the sensor used. The only lenses I use with this camera is the PL 14-50 f2.8-3.5 and the Pl 14-150 f3.5-5.6.
They are sharp at every aperture throughout the focal range. I don't need to think about what aperture to use at a certain focal length. It just makes using this combination fun. I don't think I'll ever sell them, even though it only produces a 7.5MP file.
