Thanks very much! My options are growing. One thing that I'm a bit unsure of is what to do the my filters. Right now I have three lenses (one LF, 2 35mm) that take 52mm, 67mm, and 77mm filters. Also, I have 52mm, 77mm, and 82mm filters, and a rabbit-like collection of step-up rings. I'm reluctant to part with the (hard-earned) filters in order to standardize with new ones. Any ideas on filters/holders that are high-quality and relatively inexpensive? Thanks again.
