Opps my fault thought it was a 3.2, but guess it is a 4.1. Af for the filters you will have even more DOF problems with them. It reduces it down to nothing in some cases. You end up increasing the aperture (to increase DOF) so you end up needing more light (flash). Thust my issue... DSLRs help with useable higher isos, but I still plan to get a ring flash when I upgrade.

I would love to get a set of coated Hoya macro lenses to help alleviate the DOF issue....which is a very tough area like you said.
