Re: Go with the Panny 35-100 f2.8

f2.8 is light per unit area which will be exposure. Total light captured (and so noise other than in the deep shadows) will depend on f-stop (well, strictly T-stop, which is the measured value, rather than the calculated one) and sensor area plus a smaller factor based on the sensor itself.

For DoF you scale by crop factor to allow for using a shorter focal length lens to get the same framing, but the shorter focal length gives more DoF.
