The hybrid gadget I never knew I wanted launches this month — Sony's QX Series smart-lens cameras. The two "lens-style" cameras, as Sony calls them, are nothing like you've seen before. The QX 10 ($250) and QX 100 ($500) can be attached to and work with both Android and iOS devices to give higher-quality imaging to the mobile device's cameras. Or the lens cameras can be used alone, with the phone or tablet acting as viewfinder.
The QX100 has a 20.2MP CMOS sensor, an f/1.8 lens with ISO of 160-25600 and 3.6x optical zoom, which can be manually adjusted with a just-like-a-real-camera-lens control ring. The QX10 has a smaller sensor than the QX100 at 18.2MP, but it does include what many iPhoneographers lack: zoom. The 10x zoom lens handles an ISO 100-12800 and comes in a black or white finish. Both smart-lens cameras have their own shutter release functions — meaning the smartphone doesn't always have to be present — as well as space for a memory card and rechargeable battery.
