If we look at F2.8 as an advantage, when shooting say a small kitchen wont getting everything in focus be a problem due to the shallow depth of field. So id have to up the aperture to about 4 which then brings us back to the same light sensitivity ? I might be wrong though.

Yeah, if you step down to f/4 then you lose the advantage. That said, wide angle lenses tend to have huge depth of field.

Using the DOF calculator, 8mm f/2.8 MFT lens focused at the hyperfocal distance of about 5 ft, the DOF extends from about 2.5 ft to infinity.

So it largely depends on how close you intend your subject to be.

You can play around with this DOF calculator (I used the Panasonic G3 as a stand-in for G7):

Jake, how much does 7mm on MFT translate to on an APSC sensor. 14mm ?
