The Alpa Si 3000 is a 35mm SLR sold under the Alpa name, which by this period was produced for Pignons rather than as one of the earlier Swiss-built Alpa reflexes. It sits in the consumer SLR segment rather than the precision rangefinder/SLR tier that established the Alpa reputation.

Auction data for the Si 3000 in the UK is thin: a single recorded saleroom result from 2017 hammered at £300, so any sense of what one is worth today rests on that lone hammer price rather than a meaningful range. Buyers researching what a Si 3000 sells for in 2026 should treat that figure as indicative only and watch for further auction comparables before settling on a value.
