is roughly equivalent to

FF 40mm F/3.4 ISO 800, 1/100s

In terms of angle of view, depth of field, dynamic range, and motion blur. In other words, using the two setups above to shoot the same subject from the same spot should yield near-identical prints (that's what equivalent means, ultimately).

I think this is absolute rubbish, get real, no way this is true, you are talking garbage, prove it? ISO800 on FF same as ISO200 on m43 no way, pixel size of 5dmk2 is 6microns, gh1 is 4.4 micros, its these little things that gather the light remember. You are confused there is just no way FF has any sensitivity increase that you are saying over any camera, garbage garbage garbage.

There is nobody needing to prove the relation between these sensors/systems. It's already done. The one who needs to get real is actually you Adventsam. It's a bit sad. Even more sad is that you have repeated this several times.
