Q: 1. I purchased a 77mm Tiffen Variable ND Filter from you recently--can I get an adapter to adapt this to my Olympus 40-150mm Pro f2.8 lens? Also, is there any problem adapting ND Filters?

A: Without checking, I'm pretty sure you can get an adapter here from B&H. There should be no problem since your 77mm is larger than the 72 mm size of the Olympus lens B&H Shows it to be. Sometimes there is a problem with the filter causing light drop off around the edges but I would think you should be OK with a normal adapter, but you could also see if they have a thin adapter specially designed to minimize that problem in wide angle lenses where it is more prevalent (those in the 24-70 range), etc., but at 40 mm, I'm thinking you wouldn't have a problem either way!
