Based on the \"system\" image presented by Olympus that includes the 75/1.8 next to lenses of know dimensions the 75/1.8 appears to be 65mm in diameter and 67mm in length.
There FF lenses of about the same size. The Pentax 77/1.8 is about 64mm in diameter and 73mm in length with an m43 adapter. Minolta MD 75/2 is about the same as that (also with adapter).
So it looks like this one is a bit shorter than those two options.
Olympus does warn that the these are mockups and the final dimensions may be different.
As far as being smaller because of a smaller image circle I\'m not sure. I don\'t know enough about optics.
