Pignons Alpa 10d Half-Frame (halbformat)

{"overview":"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. 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.","buying_guide":"Inspect the shutter at all speeds (Alpa cloth shutters often need service after decades of storage), check the rangefinder\/reflex prism for separation and haze, and confirm the half-frame mask and frame counter operate correctly, since a converted or incomplete example is worth far less than a factory-original halbformat body.
