I hope that camera is working well for you. Please post a review for it. I don't think anyone has posted a review for it yet.

Filters usually go on the front of lenses. The exceptions are long telephotos and big wide angle lenses where the filter size is prohibitive. Some of those lenses have drop-in filters or allow you to attach filters on the back. With your lens, I think attaching a filter on the back would mess up ther focus. Those attachements are made to work at a set distance from the lens. If you put a filter in-between, I think it would throw everything off.
