I've been shooting with an RZ67 ProII for years, but always in a "stock" configuration. I just recently picked up a ProIID and am picking up a few accessories for it (L-Grip, Winder II, etc.). I've noticed that there are a number of different focusing screens for it and am considering getting a split rangefinder type screen. I believe that is the "E" version. While researching this, I noticed a number of other screens made by Mamiya as well as some third party screens, which report to offer a brighter image on the ground glass. I'm wondering if anyone has experience with these screens and can offer any recommendations. Thanks!
