The Ernemann HEAG XII (Model II) is a folding plate camera produced by the German maker Ernemann in Dresden during the early 20th century, before the firm was absorbed into Zeiss Ikon in 1926. It was offered as a mid-range folding camera for amateur photographers working with glass plates.

With only a single recorded UK auction result, the HEAG XII (Model II) sold for £70 hammer in October 2024 — a wholesale saleroom figure that excludes buyer's and seller's commission. On the evidence available in 2026, this is the only data point we have, so it is not yet possible to quote a meaningful range or median for what the camera is worth today.
