The two cameras, which attach to a variety of smartphones, feature a BIONZ image processor, Wi-Fi, NFC and shoot 1440 x 1040 video at 30fps.
The $599 DSC-QX100 packs a 20.2 megapixel, 1.o type Exmor R CMOS sensor with 3.6x optical zoom into a 62.5 x 62.5 x 55.5 mm, 179g package.
The $279 DSC-QX10 offers a slightly smaller 18.2 megapixel, 1/2.3 type Exmor R CMOS sensor with 10x optical zoom and weighs 105g.
Connecting wirelessly, the cameras use a smartphone as the real-time viewfinder, to control the shutter, start and end video recordings and alter the shooting settings.
The Wi-Fi connection allows the cameras to operate away from the smartphone, meaning the DSC-QX100 and the DSC-QX10 can be placed in hard-to-take locations and controlled with the smartphone.
Both lens-style cameras boast a rechargeable battery, micro USB cable and a memory card slot.
