Re: Sorry, it is not as you say. Not even close.

I prefer to say "equivalent" rather than "effective". Thus, 50mm f/2 1/200 ISO 100 on mFT is equivalent to 100mm f/4 1/200 ISO 800 on FF (note that the focal length and f-ratio double, the shutter speed remains the same, but the ISO quadruples).

This is not totally correct if the m4/3 camera is isoless.
