The first impression was great, the zoom and also like the image stabilization is great. It also succeed with zoom blur photos.
Well I took a few shots with the Ixus 500HS and with my old Ixus 40 (each having approximately the same focal length) Comparing I put no real improvement clear to me, in some shots the BQ my Ixus 40 was even better. Since I had really expected of the 500HS more.
Conclusion: If you have no small Ixus will be very satisfied with the camera securely, alone of Zoom's been really great.
As an improvement in image quality compared to my current Ixus 40 stood out for me in the first line in the foreground, the camera for me was not suitable.
I have therefore returned.
