Q: 1. What is the major differences between the PL-C 52 and the PL-C 52Wll?

A: The difference between the PL-C 52 and the PL-C 52WII is that the PL-C 52WII has a wheel so that you can rotate the Polarizer while it is in the lens. This a very valuable feature and well worth the extra bit of cash.

Q: 2. Does this filter work with the older 2.8 version of the 300mm lens, i.e. version I ???
