The Konishiroku Semi Pearl is a Japanese folding rollfilm camera producing half-frame 6x4.5 exposures on 120 film. It was made by Konishiroku, the predecessor of Konica, and falls within the family of Pearl-series folders the company produced from the prewar era through the 1950s.

Auction data for the Semi Pearl is thin: a single UK saleroom hammer result of £125 is on record, so today's market value should be treated as indicative rather than a reliable median. Hammer prices at auction tend to be condition-sensitive, with clean bellows, working shutters and unscratched lenses determining whether a folder of this type sells for closer to the lower or upper end of comparable Japanese-folder results.
