The Mason Field camera is a large-format wooden field camera, a folding bellows design of the type traditionally used for landscape, architectural and studio work on sheet film. Mason is a lesser-documented maker in this category, and specific production dates for this model are not established in the available reference data.

Recorded UK auction hammer results for the Mason Field camera are limited to two late-1990s sales at £103 and £149, giving a median around £126 and a range of £100–£150 at saleroom level (wholesale, excluding commission). With no recent data points, what a Mason Field camera sells for today depends heavily on condition of the woodwork, bellows and any accompanying lens, and on whether buyers in the current market treat it as a user or a display piece.
