The Sony DSC-QX10 and DSC-QX100 lens cameras for use with smartphones seem to have polarized opinions in the press with regard to their usefulness with some critics claiming that they are products that are looking for a purpose.

Having recently acquired a Sony Xperia Z1 for myself and already owning a DSC-QX10 Lens I decided to get myself a case for the Z1 which would allow me to attach the lens to the camera without the need to use the slightly chunky mount that comes with the QX10.

Entry level camera, lag is an issue for wifi or nfc connectivity though not always. Price is too high for its spec, but I guess for the size, look and coolness that bring the price up.

Easy to Use; Good Battery Life; Great Resolution; Great Zoom; Small / Compact

Complicated Controls; Lag / Shutter Delay; No Viewfinder

Works as expected, a nice techy unit, but does not take pics as fast as i would like at times. Overall happy with the device.

I think Sony needs to update the app. The app is not stable and cannot delete the photo in the micro sd card. By the way, maybe bluetooth 4.0 connection will be better than wifi.

The color is pretty nice and match the gold iPhone 5s; It works good, gives you a more high quality photo, plus 10x optical zoom for iPhone; If you just save 200M pixels into cellphone, you can easy to share it immediately

It is easy to disconnect or connect slow down if I leave my iPhone 5s just about 30cm far away the len; I do not have NFC, so the wifi password post inside the cap looks stupid and also cannot be change

The Sony QX10 allows you to markedly improve your smartphone camera without changing your phone. At under £200, just how good is this lens ...

The Sony QX10 was released as part of a pair of now models which, along with the Sony QX100, are aimed at transforming smartphone photography. Read our Sony QX10 review to find out whether it's successful or otherwise

Great for inconspicuous shots; Battery indicator welcome; Image Quality

Lag experienced when shooting fast moving subjects; Slow to connect; No Raw support

Great for fun and maybe serious photography for some people. Light weight and responsive without lag.I use it mainly for fun and instant camera in my pocket.Overall great product to have, I will be going for the higher model soon : )

Easy to Use; Fast Shutter Speed; Great Resolution; Great Zoom; Small / Compact

If you have read my recent column - " Instagram, EyeEm an Co. - or how your Smartphone Photos can become your own Art " - you already know that I'm a big fan of smartphone photography since my smartphone is always with me.

The Cyber-Shot DSC-QX10 adds to what's been an extraordinary year for smartphone photography. We've seen phones with 41-megapixel sensors, 10x optical zoom lenses, and now the QX10 – an external camera that clips to your smartphone.
