I have an old old RB67 that still performs fantastically. Recently I have been shooting film more and more again for portraits. I came to the conclusion that if I am going to try and make all my digital shots look like film I might as well shoot film. I have owned my RB forever and love it but I only have the 90mm. I almost bought a 127 f 3.8 lens from KEH for about $100, but I started to think that what I really want is the RZ67 pro 2 with 110 f 2.8 kits I see on Ebay for $750 to a grand everyday. Please RZ/RB owners give me your honest assessment is the RZ67 that much better ? I hear it is lighter which would be nice in the field.
