I am not trying to turn this post into an 'equivalence' war, but your statements about APS-C vs M4/3's 'lens speed' is patently incorrect and misleading. An f/4 aperture on an APS-C sensor is exactly 1 stop slower than an f/2.8 aperture on m4/3's. The Depth of Field at those apertures is roughly the same -- but in regard to lens speed, they are not the same.

I cannot understand for the life of me why this concept is so hard to grasp. Total light required by a given sensor size has no effect on exposure values. If it did, every light meter made would have to have a setting to input sensor size prior to taking a reading.

My E-M1 at ISO 200 and f/2.8 in a given lighting situation will require the exact same shutter speed as an APS-C sensor camera or a 35mm FF camera at those settings in the same light.

I won't post any further about this on this thread out of respect to the OP, but wanted to make sure the air was clear.

Not gonna go there anymore.  We could go 50 replies deep and I know from past experience in this place that you nor anyone else with like thinking is going to change their mind.  Lets just let it die here.
