This is a sensor and lens format used by Olympus and Panasonic for their mirrorless camera ranges. The MFT sensor measures 17.3 x 13.0mm, so it’s smaller than the APS-C sensors used in rival mirrorless cameras. This does have a modest effect on overall image quality, but the payback is the both MFT cameras and lenses are substantially smaller and lighter than rival APS-C models. The MFT format also has a slightly squarer 4:3 (four-thirds) aspect ratio, which some photographers might prefer.
Camera types explained
Digital cameras come in a multitude of different types and sizes, and some of the jargon can be quite unhelpful. For example, 'compact' cameras aren't necessarily compact and the real difference is that they have non-removable lenses. DSLRs and CSCs are both examples of interchangeable lens cameras, or ILCs, and these are differentiated by their design, sensor size and intended market. Most novices start off with a compact camera, move up to a DSLR or CSC when they become enthusiasts and then upgrade to a full-frame or medium format camera if they turn professional.

A made-up word to describe somebody mid-way between an amateur photographer (consumer) and professional (prosumer). A ‘prosumer’ has typically gone beyond snapshot photography has become interested in photography as a hobby or ultimately a profession, and has a certain amount of technical knowledge.
A more advanced version of a point and shoot camera with a much longer zoom range and, sometimes, more advanced photographic controls. The 20x or 30x zoom range makes these cameras much more versatile, but they use small sensors so the picture quality is limited.
Many smartphones have pretty good cameras. The best ones have sensors about the same size as those in point and shoot cameras and fixed focal length lenses. The lack of a zoom is a restriction, but otherwise the quality is just as good. There’s even a growing art movement around mobile photography.
An older camera designed still used by celebrated German manufacturer Leica. The ‘rangefinder’ is used for focusing – as you turn the focus ring on the lens, a small mirror in the top of the camera rotates to line up a ‘ghost’ image with the main image in the viewfinder. When this ghost image lines up, your subject is in focus.
