Re: shutter speed of an f/1.4 with the DOF of an f/2.8

The required amount of flash power for a given scene, is also f/1.4 equivalent.

MFT is like having your cake and eating it too.

And then there is the talk about ISO noise, which is a bit silly: ISO 200 in MFT is equivalent to ISO 50 in full-frame. Do you really need to shoot at ISO 50? (only speaking of noise levels, not exposure)

What are you talking about?

Are you talking about
noise level of ISO 200 @ FF == noise level of ISO 50 @ m43?

I think it is easier to think using camera phone if you do not understand the concept we are talking about here
