The Long Focus Premo is a wood-and-brass plate camera made by the Rochester Camera Manufacturing Co., one of several Premo-branded view and folding cameras the firm produced in the late 19th century. As its name suggests, it was configured with extended bellows draw for long-focus work, positioning it toward the more specialised end of the Premo line when new.

Auction evidence for the Long Focus Premo is thin: a single Christie's hammer result of £368 from 1998 is the only data point in our records, so a meaningful current price band cannot be quoted with confidence in 2026. Buyers asking what a Long Focus Premo is worth today should treat that figure as historic context rather than a guide to what it sells for at saleroom level now, and condition of the bellows, wood and brassware will drive any modern value far more than the model name itself.
