Digital Photography Review Connect reports: [edited]
Sony has introduced a pair of digital cameras designed to attach directly to your smartphone. The QX10 and QX100 are cameras that clip onto your smartphone, which is used to operate the camera and view photos. The compact QX10 has a 1/2.3" sensor while the QX100 has a large 1-inch-type sensor and fast 3.6X zoom lens. The QX100 is essentially a Sony Cyber-shot DSC-RX100 II without an LCD. The cameras are priced at $250 and $500, respectively.
The Sony Cyber-shot DSC-QX10 and QX100 offer a totally new way of shooting on your mobile device. These cameras leave the world of tiny sensors and fixed lenses behind, offering you a choice of high zoom power or excellent photo quality. But are they worth the price?
The QX10 features an 18-megapixel sensor and a 10X optical zoom lens. Sure that's more pixels than any smartphone - aside from a few Nokias - but will the typical smartphone user notice the difference? As for the zoom, you can pick up teleconverters such as this one for a lot less that the QX10. Sure, you can't zoom in and out, nor will the image quality be as good, but $35 is a lot cheaper than $250.
While it's based on the RX100 II, the QX100 is a bit underwhelming. On the positive side, it offers the same high-quality lens and sensor as the camera on which it is based. That said, it's missing quite a few features, including shutter priority and manual exposure modes, adjustable ISO sensitivity, Raw support, and Full HD video. Add in the bulk and the price ($500) and you might be wondering if you should just carry around a premium compact camera instead.
