just sharing, updated the nex5 and lens adaptor.. tried with 3 A lens with regards to the AF speed...
SAL50F18 - 5-7seconds (P mode, Daylight, SAM)
SAL2875 - 5-7seconds (P mode, Daylight, SAM)
SAL70300G - approx 4seconds (P mode, Daylight, SSM)
A bit disappointed at the speed, but better than nothing
I notice sometimes (quite a lot) the focus lock beep dont sound, I'm not sure if its a bug or the NEX5 cant secure a lock. Also AF alluminator doesnt work with A-Lens attached also.
the softkey is great!
Hope everyone enjoy the new firmware
