This sale is for an super rare, excellent condition Bronica SQ 135 split image / microprism focusing screen – suitable for all Bronica SQ series cameras (SQ, SQ-A, SQ-Ai, SQ-Am and SQ-B) and designed for use with the SQ 135N and 135W backs.
It has some obvious scuffing but nothing serious and almost all around the edges and outside the marked 135 area, works perfectly; better than many, super rare.
This screen would be great in its own right as a focusing screen, or as a replacement for your existing damaged screen. Try finding another one!
