Here, I have inserted the image for you, but I disagree with what you are trying to show with your size comparison image. The size comparison is not right. The Olympus lens is a weatherproof 24-80mm lens with constant f/2.8 max aperture. The Fuji lens is just 28-83mm f/2.8-4, a huge difference.

Actually the Olympus is a 12~40mm f2.8 and the Fuji is an 18~55mm f2.8~4.

If you want to compare equivalents the Olympus is a 24~80mm f5.6 and the Fuji is 27~83mm f4~5.6

OK, I forgot to put in "equivalent" in what I said.

You made focal length equivalent but left the apertures the same. That made the Oly lens look better than it is.

The Oly lens is wider. The Fuji lens is brighter.

One could also add performance in the equation. Is it compared with equal vignetting (i.e. total light gathering), resolution and corner sharpness?

Agree.

My understanding is that this version of the Fuji lens is excellent. So is the Oly lens. I don't know which one outperforms the other.

Fuji make very good lenses. I think it is just a general comment when comparing systems of different sensor sizes.
