Comparison @ 45mm

Many M4/3 lenses cover the 42-45mm focal length. And there is a good reason for that. This corresponds to 85-90mm in traditional 135 film format, which is the well known portrait focal length.

Here is a collection of M4/3 lenses covering 45mm, both primes and zoom lenses:

From left to right: Lumix X PZ 45-175mm f/4-5.6, Olympus 45mm f/1.8, Lumix X 35-100mm f/2.8, Panasonic-Leica 45mm f/2.8 1:1 macro (custom hood solution)

Comparison at 140mm

A number of zoom lenses include the 140mm focal length. I have tested five of them here. They are laid out below:
