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.

I think everybody else knew what I meant.

Cool.

True equivalence does not exist;

Yeah it does. Equivalence answers this question: if I want the same image in terms of angle of view, depth of field, noise using the same shutter speed from two camera systems, what are the settings required?

By extension equivalence answers this question: are there any settings in one system impossible to duplicate in the other?
