Hi,Ken,I'm happy you got helped,Yes Richar is right,go ahead try one,also Airy idea
get a DK-17m,for me remove screen in and out is no big deal,I use my thumb nail loose the metal spring,and the 3m magic tape (small enough to pick the screen) on a plastic stick to pick out the screen,as to install,so far the G2 screen stuck on my Df,I did try type K,P,H2,all of them are for the F3 camera some are F or F2 that I got from the Bay,as for the mod,try Richar site,good info,I like the 12mm center circle all microprism of G2 and bright,only affect the 28mm get dark tunnel view,Df pair with MF lens( Nikkor Ai-Ais) is a joy to take photo,sorry for my broken langue.
