PL 14-150mm F3.5-5.6 on Olympus E-1
This is another excellent lens from Leica made for the Panasonic DSLR. My copy is sharp and contrasty throughout the focal range and at all apertures. This is truly an amazing lens. I use it on a body that has no IBIS; e.g. E-1, E-420, L1. It gives these cameras a new lease of life.
