Alex what do you think of this one?

I know there will be sometimes when i will need to keep the filter on (extreme dust, rain, etc) as i mostly shoot doc projects.

That's exactly my line of business, docs.

The filter is the same, it does not have multi coating (not really bad) and it's regular size, my old HVX200 with a regular size filter would not fit the shade, after I replaced by a slim it was fine.
