The Welta Weltur is a folding rangefinder camera produced by the German maker Welta Kamera-Werke for medium-format roll film. The 4.5x6 variant exposes 16 frames on 120 film and was offered as a compact alternative to the 6x6 and 6x9 versions in the Weltur range.

With only a single UK auction record on file — a 2005 hammer of £175 at saleroom level — there is no meaningful price range to quote, and that figure reflects wholesale auction conditions rather than dealer retail. Buyers asking what a Weltur (4.5x6) is worth today in 2026 should treat that lone result as indicative only, since values for folding rangefinders of this era are highly condition-sensitive and thinly traded.
