But that's not all at all, folks! Thanks to the update, the QX-10 and the QX-100 will now pair with an NFC-enabled smartphone significantly faster. Still, in order to benefit from the reduced NFC One-touch connection time you'd need to have the companion app for the lens-style cameras, PlayMemories Mobile, updated to version 4.2 or higher.
Not long ago, the QX10 and QX100 received an incremental update that cranked up the ISO sensitivity of both cameras. Additionally, the accessories were finally enabled to shoot videos with a resolution of 1920 x 1080 pixels, as up until then the cameras could only shoot 1440 x 1080-pixel video clips.
It's important to say that Sony's lens-style cameras can't be updated over-the-air, but you can follow the sources at the link and do so via your desktop PC. You can also go ahead and check out our hands-on with the QX-10 and QX100.
