The aspect ratio doesnt matter. Its ignorable.
But for folks like you who cant ignore minutia, the "fix" back to identical aspect ratios all around is sooooooo friggin simple it doesnt need description. Try getting real every once in a while. Maybe (just maybe) youll find it somewhat refreshing.

All of us grownups know that equivalence has no practical significance. I'm just showing why it's a bogus concept.
The only use we have for crop factor is to change the "effective" focal length. We already know that a reduction in DOF is a side effect.
We also know that we can get back the lost DOF by stopping the lens down and slowing the shutter. That might help hide some noise. We don't have to get the ISO involved.

The guys who started the equivalence in f stop did that because they say the 300mm f/2.8 for M43 is equivalent to 600mm on the FF if that the case there is no 600mm f/2.8 in FF so they must say that the 300mm f/2.8 for M43 is only equivalent to 600mm f/5.6 in FF. That's all the reason why they came up with the equivalence thing.

What they always overlook is that there is still a significant quality advantage to the larger format.
Equivalence is just a way to rationalize spending less money for a smaller, lighter camera.
Taken to the extreme, you end up using your smartphone.

If you want to have the aperture displayed correctly with MF lenses you have to enter the lens data for each of the lens you use. It's in the NON CPU LENS DATA menu. You can enter the data for up to 9 lenses. Whenever you mount the lens you will have to select the lens number. This is not only for the camera to display the correct aperture in the viewfinder but also to get the Matrix Metering to work correctly.
This was my problem, all lenses were entered but I thought the camera would recognize the lens when attached, didn't know I had to go into menu and call up that particular lens everytime I used it. Been using them for yrs but just never noticed the discrepancy before

Since the lenses are non CPU there is no communication between body and lens thus the camera doesn't know which lens you mount on it.
