Micro Four Thirds dates from 2008 and is shared by OM System (formerly Olympus) and Panasonic. The sensor is a quarter the area of full-frame, which is what makes the lenses so much smaller.

Where the format wins

Reach and weight. The 2× crop means a 300mm lens frames like a 600mm, so wildlife and sports kits that would be unmanageable on full-frame become hand-holdable. The OM System 300mm f/4 with a body weighs less than many full-frame 400mm lenses alone.

Travel is the other case: a two-lens MFT kit fits in a bag that one full-frame zoom would fill.

Where it does not

Depth of field and low light. A 25mm f/1.8 gives the angle of view of a 50mm and the depth of field of roughly f/3.5 on full-frame. If heavily blurred backgrounds are the point, this is the wrong format.

Read the equivalents

Everything is 2×. Turn on 35mm-equivalent values when comparing against other mounts, or the numbers will mislead you.
