Upload & Sell: Off
There is something like a 16 to 1 penalty for Lytro. You use a 16 MPx sensor and get about 1 Mpx out of it. It requires special lenses bonded to the sensel array so you can't just turn it on and off.
I don't see it inside a DSLR this decade and probably not the next. However, alexdi thinks it will be. Cellphones, who knows?
When sensor arrays advance enough to have 256 Mpx, then you can have a 16 Mpx Lytro. But by then DSLRs will have 256 Mpx and will be doing other tricks with the excess pixels like puttin out 64 Mpx images with 20 stops dynamic range (put neutral density filters on 128 Mpx sensels).
