The Olympus Mju III Wide 100, also sold as the Stylus 100 Wide, is a 35mm film compact camera from the late Mju/Stylus lineage of weather-resistant point-and-shoots. It was positioned as a wide-angle-capable everyday compact, aimed at users who wanted a pocketable autofocus camera with broader framing than the standard Mju zooms.

At recent UK auction, hammer prices for the Mju III Wide 100 have sat in a narrow band of roughly £40–£56, with the two recorded sales averaging around £48. Today the model sells for modest sums at saleroom level, and condition, working flash, and a clean lens are the main factors separating the low and high ends of that range — buyers looking up what one is worth should treat these wholesale results as a floor rather than a retail price.
