If you believe the rumours at SonyAplha, Sony has developed a new category of camera called a 'lens camera' that simply clips to the back of an Android or iOS smartphone. It gets over the issues of miniaturisation by sharing the processing between the lens and the smartphone.
The lens has a built in sensor, Bionz processor, Wi-Fi/NFC, micro SD slot, and a chargeable battery. The smartphone becomes the viewfinder and controls the lens via Wi-Fi.
According to SonyAlpha this is a completely new way of doing photography and, as the camera app and viewfinder function is via the smartphone, it makes for a more affordable lens camera. Expected release date is 4 September.
I can see the patent lawyers having a field day trying to protect this concept from imitation. A real camera lens, a larger sensor, and the functionality of Android or iOS to drive it, and share images – great thinking Sony.
SonyAlpha rate this rumour an SP5 – almost certainly correct.
