The ISO Standard is an Italian-made camera produced by ISO of Milan. It is a rare postwar product from a small Italian manufacturer, and survives today primarily as a collector's item rather than a working photographic tool.

With only a small number of UK auction records to draw on, hammer prices for the ISO Standard span roughly £750 to £1,600, reflecting wholesale saleroom levels rather than retail asking prices. As of 2026, the value of any individual example is highly condition-sensitive, and the thin sample size means the price a given camera sells for can swing significantly between sales. Buyers researching what the ISO Standard is worth should treat the figures here as broad guidance rather than a tight market price.
