Hello - It's my 1st post here, but probably some of you are familiar with me from RangeFinderForum.com I recently became happy owner of very basic ETRSI outfit. Great camera, I immediately felt at home with its ergonomics. The only thing I would like to improve is viewing image brightness - I am spoiled by OM viewfinder with 2-13 screen installed. This leads to a quest for brighter focusing screen for ETRSI (I have Bronica plain matte screen in camera). Are there brighter focusing screens - either OEM or aftermarket - available for Bronica ETRSI?
