I thought we'd dealt with that one recently.
The view is smaller, not dimmer.
An aperture is an aperture is an aperture.
The sensor size does not affect it.
If I put my Zeiss 180mm f2.8 medium format lens on 35mm, it does not become an 
f2. 
I can put it on my E-P2 and have done for fun. Does it become an f.1.4? No.
My Voigt. 25mm f0.95 is still that aperture on mFT.
It's DOF that is affected.
