Excerpt: Good. BUT NOT PERFECT !...................................... Very good camera. Really nice results especially in dark. Perfect that Canon add special mode (high ISO at 1/4 resolution) for these purposes which is available on selection rotary wheel. I am sure you will use this feature very often. Okay there is some loose of details but picture at all looks nice. Precise construction with excellent display.
Excerpt: I love this camera. I only use a compact camera and I carry mine with me all the time. I get much better photographs with this camera than with other compacts I have used. The prices was a bit steep, but the photos are worth it. I hope that the number of cameras available in this class increases as seems to be the case. Problems: The problems and weaknesses are the same one's noted in DPreview's in-depth review of the camera.
Pros: The fast lens and the relatively high ISO ability of this camera make it one of the best I have ever seen in a P&S camera that fits in your pocket.
Cons: Pop up flash is a real pain. The camera has no grip on it meaning you wind up holding it with both hands - fingers on the top, thumbs on the bottom. Problem is your finger(s) on the left hand rest on top of the flash. Also, only 3.8 x zoom.
Summary: The image quality of the s90 is excellent for a compact digital camera. The feature set, high ISO performance (not as good as a dslr) and small size are big pluses. For many, including myself, the ergonomics of the s90 are very poor. Most notable is the pesky, free-wheeling rear control dial that moves easily and inadvertently at the slightest touch. Unless you're in auto mode(s), settings change and can mess up photos unless you monitor them.
Pros: - Combination of control ring and the small ring behind which help to control the setting easily - F2.0 focal length
Cons: - Battery not last long for whole day trip, be prepare an external battery - Maximum aperture only F8 - I am like to put a question mark on the quality control of canon which suddenly not working and stop me on shooting beautiful scenery at Sydney.
Pros: Good low light shooting. Good control - manual, aperture, and shutter speed. Nice sized screen. Unique and usable front ring dial.
Cons: Ring dial on back of camera is way too loose - results in inadvertent exposure compensation. Zoom range is too limited. Camera is almost too small, resulting in ergonomic issues Battery life is not adequate. Expensive.
Summary: This camera was brilliant, until it broke after 10 months. The pop up flash got stuck in the casing. As it was still under warranty, it was sent back to Canon, who said it would cost £250 to repair as it was 'accidental damage' and someone must have put too much pressure on it. I must be superman to put enough pressure on metal camera casing to get the flash stuck inside it. Recommend the camera, don't recommed Canon at all.
Summary: This had all the makings of being a great camera. Fast lens, great sensor, bags of features that should put the photographer in control. A worthy backup to an SLR? Well, on paper it all looks great, and the sacrifices you make against a G11 seem modest compared to the benefits of having something you can slip into your pocket. After several months of using this camera, however, I find it wanting.
