Originally posted by BigMackCam I'd be impressed by a lens that's capable of resolving sufficiently well to make good use of that sensor.
When I first saw it I pointed out the lens issue. For it to not be diffraction limited it would have to be something like a f/.5 lens or there about (maybe it was f/.7). That will give a very shallow DoF. This also assumes that it is an ideal lens and cheap cellphone lenses are pretty far from that.

Couldn't agree more. Also they are starting to run into hard limits put in place by physics. To get the resolving power they need a very wide open lens which will help with light gathering but will give an ever shallower DoF. They are getting closer to having pixels smaller than wavelengths of visible light so there will be photons that just miss the tiny wells.
I just realized something that is rather sad. We are talking about being diffraction limited at apertures greater than f/1 yet with pixel dense DSLRs it is somewhere between f/8 and f/11.
