The KGB Microdot (1mm) is a Soviet-era subminiature camera built around a 1mm format, produced for clandestine photography rather than general consumer use. Items of this type were issued through state security channels and rarely surfaced on the open market when new.

Sales evidence for the Microdot (1mm) is extremely thin: the only recorded UK auction hammer result we have is £1,200 from 2005, which sets the sole reference point for what one has sold for at saleroom level. With a single data point and no recent comparables, today's value is highly uncertain and any price assessment should be treated as indicative only.
