The Arnold Karma-Flex (6x6, Model I) is a medium-format roll-film camera producing 6x6 cm negatives. It is an obscure model from a small manufacturer, and surfaces only occasionally in the UK collector market.

Sales data for the Karma-Flex (6x6, Model I) is extremely thin: a single recorded UK auction hammer result of £250 from 2002 is the only reference point available, so any value quoted today must be treated as indicative rather than a reliable median. Because only one sale underpins the figure, today's worth depends heavily on condition, completeness and bidder interest on the day, and a clean working example could sell for considerably more or less at saleroom level.
