First of all I know this kind of topic can get pretty heated. I just want to clarify my understanding of things, so please leave your emotions aside and answer with your head. Say I have an olympus 45mm f1.8 and I am shooting at f1.8 and I compare it with a FF lens which is a 90mm and I shoot at f1.8. Both cameras are used in the very same environment and use the same ISO value. Would the following affirmation be correct. 1. Both cameras would require the same shutter speed in order to have the same exposure. 2. The FF camera would have a shallower DOF whereas the m43 camera would have a DOF equivalent to the FF if the aperture value was set to f3.6 (granted the shutter speed would be adjusted accordingly). Once more, I am not trying to start a debate, I just want to make sure my understandings of things on this matter are correct. Thanks.
