About Four Thirds User


Four Thirds User is a website dedicate to the related interchangeable lens camera system standards; Four Thirds and Micro Four Thirds.

This includes cameras, lenses, accessories and software, as well as services, provided by Olympus and Panasonic Lumix, as well as related products produced by Sigma, Yi Technoloies, Tamron, Adobe, Phase One, and many other companies.

Four Thirds User was originally set up in 2007 with funding from the Four Thirds Consortium, although it has always been a privately-owned independent entity run by Ian Burley (CEO The Write Technology Ltd.)

As of summer 2019 the site is under redevelopment although this discussion forum remains open and we welcome your participation!
