Sony reportedly planning lens attachment for iOS, Android smartphones to rival Nokia Lumia 1020

Images leaked this week suggest Sony is prepping a wireless lens add-on for mobile device users who want the full-fledged shutterbug experience.

First reported by Sony Alpha Rumors, the photos show the DSC-QX10 and DSC-QX100 lenses, both with built-in sensors, a Bionz processor, Wi-Fi/NFC connection, and an SD card slot.

Without an LCD screen or other camera controls, the lenses are meant to attach to and be controlled by an iOS or Android smartphone or tablet.

"This is nothing like we have seen before," Sony Alpha Rumors said. "For the first time you can shoot top quality images with your smartphone. Forget [those] iPhone or Android lens kits!"

According to the report, Sony will "soon" launch two models — one with a RX100MII sensor and Zeiss lens, which will reportedly offer the same image quality as the Nikon 1 system. The other, smaller lens features an 18-megapixel CMOS sensor with a 10x zoom, similar to the Sony WX150.

Prices and an exact release date are unknown, though Sony Alpha Rumors suggested a 4 September launch.

If these lenses hit the market, Sony could offer some fierce competition to Nokia, which just last month unveiled the 4.5in Lumia 1020 Windows Phone 8 smartphone with a 41-megapixel camera.

The device comes with optical image stabilisation, Zeiss optics with a 6-lens design, a manual shutter, and Xenon flash; while it can capture 34-megapixel and 38-megapixel image files, the phone also saves a 5-megapixel version for sharing.
