What Micro Four Thirds means in practice
A Micro Four Thirds sensor at 16.1MP doubles the effective focal length of any lens mounted on it, so telephoto reach comes cheaply in both size and money and wide-angle coverage costs more of both. It is the smallest of the three formats here, and the systems built around it are correspondingly compact.
Stabilisation and weather sealing
In-body stabilisation steadies any lens mounted on it, including primes with no stabilisation of their own. The body is weather-sealed.
