The Hermagis Micromegas is an early French-made camera produced by the Parisian optical house Hermagis. It is a collector-grade piece from the early era of photography rather than a general-use model, and surfaces only rarely on the market.

Auction data for the Micromegas is extremely thin: a single recorded UK saleroom result from June 2015 saw a hammer price of £7,000, which sets the only firm reference point for what this camera is worth today. With just one sale on file, that figure should be treated as indicative rather than a reliable median, and a fresh example reaching the market in 2026 could sell for materially more or less depending on completeness, condition and bidder interest on the day.
