We're excited about Sony's lenses for iPhone and Android smartphones that give greater camera power instantly via Bluetooth. And now, according to BGR sources, they have a name – EspressOn.

The EspressOn lenses are rumoured to  be arriving in two forms. The first, DSC-QX100, will sport the point and shoot RX-100 II's same 20.0-megapixel sensor with f/1.8 aperture and 3.6x optical zoom. The cheaper DSC-QX10, like the WX-150 camera, will sport an 18-megapixel CMOS sensor and f.3.5-3.9 lens. Both offer a great jump for nearly all smartphones out there – except, perhaps, the Nokia Lumia 1020 of course.

Each of the lenses should have its own power button, microphone, display for battery and SD status, a shutter button, tripod mount, multifunction jack and zoom level. The pricier DSC-QX10 will also have a ring control for manual changes.

While there was no date given on the release of the EspressOn lenses it's a fair bet to assume they'll be appearing alongside the Xperia Z1 on 4 September at Sony's IFA announcement event. Pocket-Lint will be there to bring you the details live.
