The Ernemann HEAG I (early) is a folding plate camera produced by the Dresden maker Ernemann in the early twentieth century, before the firm was absorbed into Zeiss Ikon in 1926. It was a general-purpose plate camera positioned for amateur use in its day.

Evidence of what an Ernemann HEAG I (early) is worth today is thin: the only UK auction record on file is a single Christie's hammer result of £47 from 2001, so a current price band cannot be given with confidence. As a wholesale saleroom figure that excludes buyer's and seller's commission, it suggests modest value for the model in 2026, but condition, completeness of the original lens and shutter, and bellows integrity would drive any specific result.
