I just received the Q7 this past weekend. As a 2 year user of the original Q, I thought I would provide my initial impressions. First, although the Q7 has been out for many months, I had to special order the Q7 as it is generally not available on the shelf in Canadian stores yet. retailers are still trying to sell off old Q10 stock so have been reluctant to bring in another camera. Not a good sign for Canadian sales.
The first thing I noticed were the controls are set up the same as the classic Q so that was great. Startup and operation seem much quicker which is a real bonus. AF in good light is lightning quick. The real good news is the IQ is definitely improved from the classic Q. This is the main reason for the upgrade. High ISO quality is much better and at base ISO, there appears to be more resolution and clarity to the images, so the larger sensor is a good choice. My only question with the larger sensor is why didn't Pentax include a larger sensor in the original Q? This may have muted the early criticisms.
While the build quality is not up the classic Q standards, it feels better than I expected. All in all this appears to be a great upgrade and makes the Q a much more capable little camera. A few initial pics as well.
