The Beier Beira I (also marketed as the Beika) is a small-format folding camera produced by the German maker Beier. It was aimed at the amateur market and sits among the compact folders of its era rather than at the professional end of the line.

Auction evidence for the Beira I is thin: a single UK saleroom hammer result of £198 in November 2021 is the only data point on record, so today's worth is best read as a rough indication rather than an established price band. Buyers asking what a Beira I sells for at auction should treat that figure as a guide for a presentable example, with condition, completeness and cosmetic wear likely to swing the value either way.
