ISO and f/stop

The f2.8 lens on the Nikon isn't as fast or bright as the f1.8 lens on the Sony.  Even with the larger sensor in the Nikon and being able to use a higher ISO to compensate with less IQ loss, the faster Sony lens let's in more light [snip]

Sony:  10.4 / 1.8 = 5.78

Nikon: 18.5 / 2.8 = 6.61

So the Nikon lens lets in more light...
