Sounds exciting. Will wait till I see sample images before celebrating though. If a small sensor using this technology can perform better than a APS-C sensor now, I guess it is time to usher in APS-C sensors with even more megapixels / usable higher ISO.
a smaller sensor will result in a deeper DOF and will pose a bigger challenge for photographers aiming to get shallower DOF.
Lens makers will probably have to invest more to come out with specialty lens with extremely shallow DOF to accomodate the smaller sensor sizes.
he mentioned that the overall cost of producing one BSI sensor is significantly lower than to manufacturing a typical larger sensor. So end users can expect greater performance from compact digicams in the future at the same, if not lower, price.
However, i do see some flaws in this technology. There is a reason why the silicon was constructed below. The new BSI construction will add cost to the overall production process and might cost more than CCD of the same size. They did a comparison in the report of a P&S sensor compared to dSLR sensor which I feel is like comparing a QQ to a S500.
