This sale is for an very rare, used and really excellent condition Bronica SQ split image / microprism focusing screen – suitable for all Bronica SQ series cameras (SQ, SQ-A, SQ-Ai, SQ-Am and SQ-B).
It has just minor scuffing but nothing serious and mainly in the corners, works perfectly; much better than most of these screens. Perfectly ok to use.
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!
