Pignons Alpa 10d Half-Frame (halbformat)
The Alpa 10d Half-Frame (halbformat) is a 35mm SLR made by Pignons in Switzerland, a variant of the Alpa 10 series configured to expose half-frame (18×24mm) negatives rather than the standard 24×36mm full frame. Alpa cameras of this period were low-volume, hand-finished instruments aimed at the high end of the precision-camera market.
Auction data for the half-frame 10d is extremely thin: the only recorded UK saleroom result we hold is a single 2009 hammer price of £2,200, which gives some indication of the wholesale level a collector-grade example reached but is not a reliable guide to what one is worth today in 2026. Because half-frame Alpas were produced in very small numbers, value at auction is driven almost entirely by condition, completeness and provenance, and prices for comparable rarities can swing widely from one sale to the next.

Frequently asked questions
What is an Alpa 10d Half-Frame worth at auction?
On the single UK auction record we hold, an Alpa 10d halbformat sold for £2,200 hammer in 2009; with only one data point the current price is uncertain and condition-dependent.
How much does an Alpa 10d Half-Frame sell for compared with a standard 10d?
Half-frame Alpas were made in much smaller numbers than the full-frame 10d, so genuine halbformat examples typically attract a rarity premium when they appear, though too few sales exist to quote a firm differential.
Why is the price range for this camera so wide?
Because so few halbformat 10d bodies come to market, each sale is effectively its own data point and the value depends heavily on originality, cosmetic condition and whether the camera has been recently serviced.
