Olympus OM10

Olympus OM10 with Manual Adaptor
The Olympus OM-10 has been one of Olympus' most commercially successful models and that is because it was based on a very successful recipe – the OM-10 is a (feature) stripped down OM-2n, a very popular professional model. It maintained the small size and compatibility with the Zuiko system, stuck with the aperture priority mode which was so very popular in the early eighties and offered the optional 'Manual Adaptor' that could offer full manual operation. And most importantly, it uses the highly regarded OTF plane metering system of the OM-2n. These features made the OM-10 a very attractive offer, especially if you think that it was competitively priced – Olympus sold these cameras by millions.
