Summary: After buying the S5 to replace my S3 I was very disappointed with the image noise as noted on another review here. This is not a Canon only problem and it's becoming a troubling trend as megapixels are added at the expense of image quality. It's not a matter of the S5 being better than the Sony H7 or H9, it's a matter of any of these cameras being able to equal their own previous generation model with regard to noise.
Summary: We bought this camera largely based on reviews of others and to upgrade to a more manual, higher quality point and shoot. We were amazed by its video capabilities. Others give similar praise. Where we were disappointed was in the quality of the stills. The auto focus is hit and miss. My $200 Sony does better in this category. Maybe a quarter of the indoor photos we took were slightly out of focus. That's hard to forgive, but unforgiveable is the flash.
Great Camera..BUT...Received Two Defective Units! Check Yours!

Summary: I first want to say the camera is great and takes awesome pictures. However, both the first camera and replacement camera I received had a defective sensor that would cause a small dark spot on the upper right quandrant of the picture in certain conditions. Those conditions were whenever the aperture was in the range of f6 - f8 (small aperture). This aperture setting would usually occur under bright conditions (auto) or manually set.
Summary: This is an excellent camera but was let down by a bad design fault. The lens cover is not attached to the lens but to the external housing. It has to come off to prevent the mechanism being damaged when the camera is turned on. Therefore the cover has been made to come off very easily. I found it came off all the time when I didn't want it to and there is no facility to attach a filter to protect the lens.
