Sony QX10 and QX100 Firmware Update 3.00
Sony has issued a firmware update for its DSC-QX10 and QX100 camera-lens modules. Version 3.00 enables users to focus with a half-press (and take a photo with a full-press) of the shutter release, and improves upon the "NFC One-touch connection." Note that this requires PlayMemories Mobile app version 4.2 or later.
