Well Rioch don;t seem to believe your thoughts.!
And my use seems to indicate -3ev still functions with at least f2.8 lens and f4
Dependable AF at super-low minimum luminance of –3 EV
The K-3’s high-sensitivity AF sensor assures dependable autofocus operation down to a minimum luminance of –3 EV (when using 25 middle sensors), preventing the AF mechanism from slowing down or being confused by high-contrast areas in back-lit situations. It also captures low-contrast subjects with great accuracy.
Not seen any promise from Sony of Lux capability of their AF system , seems to be always missing from MilC Specs (If I was cynical I might question why !)
Milcs advertised of new super low light shooting fail to give specs !
Though Hybrids should be capable of surprisingly good AF maybe sensor noise messes with it ?

Originally posted by rawr That is very relevant to my interests. Hopefully they mean RF wireless, rather than optical wireless. It may be hard to implement, but if Pentax have done RF wireless with P-TTL support in body, that would be great. RF wireless flash support built-into the body would be a first for a DSLR, as far as I know.
If they wanted to steal a lead why not infrastructure based RF (WiFi , 802.11x)
imagine you could have Point to point just like today normal RF/Light firing but also AP based (access Point)
Each Flash would be IP based using adHoC in Point to point mode and named in infrastructure .
You could place a flash anywhere and talk to it.
And Penatx would have new revenue streams for new flashes with very advanced capabilities
