The Ernemann Bob 0 is a folding plate camera produced by the Dresden maker Ernemann in the early 20th century. It sits within the Bob series, a range of affordable folding cameras aimed at amateur photographers of that era.

Sales evidence for the Bob 0 is thin: the only recorded UK auction hammer result on file is £100 from 2005, so there is no current 2026 median to anchor a price band. Today, what a Bob 0 is worth at saleroom level depends heavily on bellows condition, shutter function and completeness of the original case and plate holders, and any stated value should be treated as indicative rather than a market median.
