The Plaubel Makina IIb is a folding strut-type medium format camera produced by the German maker Plaubel of Frankfurt. It takes 6x9cm images on rollfilm or sheet film via a back, and was positioned as a press and professional folding camera in the pre-war and early post-war period.

At recent UK auction, hammer prices for the Makina IIb have ranged from about £150 to £290, with the two recorded results sitting either side of a £220 midpoint. With only a small sample of saleroom results to draw on, what a Makina IIb is worth today depends heavily on the condition of the bellows, shutter and rangefinder linkage, and clean working examples sit at the upper end of that range.
