The previous reviews I can understand only partially, in fairness I must say that I have so far all the photos in fairly good light outside (and therefore at ISO 160) but made. There my subjective opinion, but little to complain about.
True, the pictures are at full zoom (purely optical zoom!) A little fuzzier than in the wide-angle or normal range. Please also consider, however, whether the digital zoom (right with Struch separate area of the zoom bar on the screen) is really off, preset is optical and digital zoom. That produces a digital zoom blurred images is in the nature of things that you can later on computers via image editing much better. Overall, I'm quite satisfied with the sharpness.
The offending noise can I recognize partly in colored areas (eg. As deep blue sky) while, at ISO 160 but this is negligible, because I've seen far worse in other compact cameras. However, if you want to do mostly photos with high ISO values, which should be in a different class of camera image sensor larger look (z. B. Nikon P7000 or MFT cameras with interchangeable lenses), but of course at the expense of size.
You should also consider this: keep 450mm telephoto with such a small, lightweight camera body certainly requires very steady hands or optimal light. Unfortunately, you can not manually adjust the Nikon, but must resort scene modes, a compromise which I personally can live well with my application on the (however many).
Also a small stumbling block: the default is the S9100 appears normal at 12 megapixels, but in quality. The better quality is recognized by the star next to the 12, here at the best switch immediately. Likely due to the memory card prices indeed be no real problem.
A firm favorite is certainly the high-resolution, sharp display with 921,000 pixels, which is also reflected in the bright light halfway. Sure, not a replacement for an optical viewfinder, but more than serviceable. Even with the autofocus, I had been in daylight no significant problems, the focusing was carried out even very quickly.
It's also nice the Sweep Panorama, even if the images have a height of only 560 pixels. Who needs more here, has to rely on the second panorama mode in which the images are custom built and assembled in the computer. The Nikon supported in this mode with a sort of "ghost", so that the Append is easily recognizable.
Only drawback: the battery is being charged in the camera, who wants to charge the batteries outside of the camera, the external charger must still buy it. Which in turn is not bad: in the camera of Aku can with a normal USB charger (via PC) are loaded, provided one has thereby the camera cable. So even on the go might sometimes be an advantage, if you can do without an additional charger with very small luggage Kan's.
Not entirely convinced I was also the battery power, after about 150 pictures and some consider it was over. I would like to but not overrate at this point, as this was the first charging of battery, experience has shown that there's what is happening after the first three to five cycles. In addition, batteries are of foreign manufacturers at reasonable prices available, for. Example of Bluemax.
My conclusion: certainly no competition for a P7000 from Nikon (which I also own) or G12 from Canon, but that is already established in the smaller sensor, the price and the other target groups. As a "take-along" camera, but it can convince me despite slight weaknesses thoroughly. But a glance is sure worth the competition: Panasonic TZ22, Sony HX9, Canon SX230 or Fuji F550EXR (available in some cases only shortly).
Update as of 23.03.2011:
What stands out in the camera, is the relatively clearly audible "hum" when Betaätigen the shutter button. But this is completely normal, here is the optical image stabilizer, which carries out his work. Partly also heard in other cameras, with the S9100, it is clearly noticeable. As I said, no reason to panic, the sound is completely normal.
Update as of 26/03/2011:
I once uploaded some sample images, so you can see that at least in good light you sharpness is quite alright. What I now noticed, however: the camera has, unfortunately, no position sensor, so it can not automatically rotate vertical shooting and also writes no relevant information in the JPG file, to allow the software automatically rotates. No drama, but this is now really solved and now luckily the exception rather that you have to rotate images manually.
