(SR5) NEX-5R sensor has phase detection pixels on sensor!!! | sonyalpharumors I saw this rumor this morning. I wondered when someone was going to bring something like the Nikon 1 focus system, but on a larger sensor (not sure if EOS-M offers an AF speed advantage?) It would seem like it is going to start being more and more difficult to sell APS-based DSLRs? It also makes me wonder how long Sony will invest in SLT. I have heard there is also a light loss associated with PDAF receptors (right term?) on the sensor?
