Druh Syncro is a medium format film viewfinder-like box camera made by WZFO (Warsaw Photo-optical Works = Warszawskie Zakłady Fotooptyczne), Brzozów, Poland and produced between c. 1956–60. Druh means Friend.
Druh wasn't an original Polish construction. It was a direct descendant of the Pouva Start, WZFO redesigned and more similar to the Yunkor from KMZ. Druh cameras had several finishes in their production time. Druh Synchro is a modernized version of Druh with accessory shoe and pc socket for a flash gun connection. There are also some cosmetic variations.
