Sony’s QX10/QX100 Hub Lenses have a new firmware v3.00. Improvements include the ability to half-press the shutter to focus and a reduction in NFC one-touch connection times.
Another change is the ability to use the Sony Xperia’s camera key for the shutter release. You will need PlayMemories Mobile app version 4.2 or later for this to update to work.
The QX10/QX100 has had ISO setting added and MP4 Movie Recording size changes from 1440 x 1080(30p) to 1920 x 1080 (30p).
