Nex may not need faster than F4 lenses!
Sep 12, 2013

According to an article by the respected DXOMark labs, how much light you gain from going faster than F4 depends a lot on sensor design, and most of the extra light is lost. I am not a lens expert, but what do you think?

The article at DXOMark is found under "reviews", and called "F-stop blues". Of course, depth of field is affected. The article also claims that some manufacturers fudge the ISO at the widest f stops.
