Summary: Update. Camera going back for the third time. Now I have the dreaded lens error issue where the lens won't retract and the camera won't shoot. This is subject of a repair notice which should make it free. Still the camera has been a nightmare for me. I require reliability. This has not been the case. I have had this camera for a year and a half. I wanted to have a pocket-size all-purpose camera for shooting kids and to use while skiing.
Summary: The good is that it's a well built camera that takes sharp pictures and has a great feature set for its size. I considered the Sony RX100 and this camera, the newest pocket cameras with larger image sensors. I chose the s100 since: -RX100 didn't really have a long term track record as it was only recently released. -Smaller size and weight of the S100, excellent image quality given its size.
Excerpt: I love this camera for a small still camera. Personally I think they could have made it a little bigger and given it more telephoto capabilities. You can't really fit in a pocket so, to me, you might as well make it a little bigger, easier to hold, more room for lens, etc.. But its nice to have the f2. That does, however bleed off very quickly as you move from wide to telephoto. The fuji x10 holds a wide aperture better across focal lengths.
Summary: I was really excited for this camera - there are very few in this market segment, a small compact camera intended for enthusiasts. It has full manual controls and can save images in Raw format. On the plus side, the ergonomics and build quality are excellent. It was lighter than I expected, but still feels very solid, with high quality buttons and switches. The screen is big, bright, and gorgeous. Its ultimate downfall in my mind is image quality.
Summary: I had high expectations, but Canon really stumbled with the S100. The new CMOS sensor, lens and Digic processing system have not added up to a better camera than the S95. The S95 gave really nice results in terms DOF and clarity and those qualities are missing in the S100. The S95 was visible better than the standard Powershot. I find almost no difference in IQ between my SX230 and S100, both are CMOS based HS systems.
Summary: This compact camera does many things well -- it is perfectly pocketable, very well designed (metal, made in Japan, with fantastic controls - especially the function ring on the camera's face), and almost all the settings can be tweaked manually. I was, and still am, thrilled by the possibilities it offers. For something this small it is incredibly fully featured. But for me personally actually using the S100 proved a huge disappointment.
Excerpt: Wen es interessiert... hier mal meine Geschichte über die Canon S95, 100. Ich bin Hobbyfotograf und mache mehrere 1000 Bilder im Jahr. Meine erste kompakte Canon war die S95. Eine Kompakte mit einer Bildqualität, die seinesgleichen sucht. Auch bedingt durch den großen Sensor (1/1.7“). Leider trat dann 2 Monaten nach Kauf dieser Objektivfehler auf, von dem ich bis dahin nichts gehört hatte.
Summary: auch außerhalb der von canon eingestandenen produktionsreihe (hier: no. 43.....). zum glück 2 wochen vor garantieende, zum glück wurde repariert. ist verkauft, nie wieder canon minis. schade, denn sonst eine prima kamera, aber solche unzuverlässigkeiten sind in der preislage zu riskant.
