There wasn't much of a perceptible lag in the live image, but it wasn't always smooth when panning from side to side.
It took about four seconds from the button being pressed to the picture appearing on the phone screen. That's slower than a digital still camera, but then the QX10 is a compromise between two devices and it does that quite well.
It did great in bright light and low light — the intelligent auto mode will take several pictures and merge them when there's not enough light — but some of the pictures seemed to lack a little of the brightness and color that came from a compact digital camera when I took comparison images. However, that's not to say the QX10 pictures were bad.
I found it useful to have a lower resolution version of each picture sent to my phone. They are not too large for the phone to handle and perfect for sending to social media channels or attaching to emails.
I've never been able to take such high quality photos with my cellphone, so for that the QX10 is a winner. If you like to take pictures and are always disappointed by the camera on a smartphone then the QX10 and sister QX100 are worth considering. But if you're more serious about taking pictures, you might want to stick to your digital camera.
The QX10 and QX100 will be available from late September. In the U.S., the QX10 with 10x optical zoom is expected to cost $250 and the QX100, which has a 3.6x zoom and larger image sensor, expected to cost $500.
