I thought it would be nice to protect the lens, so I was looking at some inexpensive, clear UV filters. (camera is Oly EPL-1 with stock 14-42mm Zuiko Lens) What do you think about Vivitar? I have found a very affordable Vivitar set of 3 filters. They are multi-coated and besides the basic UV, there are circular polarizer and neutral density filters in the set. I would appreciate some input on this set and/or any recommendation of other inexpensive lens filters. P.S. 14-42mm Zuiko Lens uses 40.5mm size filters, right?
