This camera just blows me away.It takes amazing pictures in full-auto mode.In situations where full-auto doesn't quite do the job as well as possible, this camera lets you change ISO settings, white balance, focus method, and tons of other factors.
Compared to the S110, I thought the ability to change the ISO setting was a big improvement over previous generations.You're actually changing the sensitivity of the sensor in the camera, allowing you to take pictures with more clarity in conditions that have less light.This, coupled with the image stabilization (which again, blows me away on this camera), allows you to not have to use flash, preserve the real look of the scene, and take a crisply clear picture.
Battery life is amazing.I haven't charged it once yet... I'm going on over 150 pictures taken now.I've taken many pictures in low light with no flash, which drains the battery faster because the sensors have to stay on longer.The battery low warning has now come on... but I've still taken over 10 pictures on low battery, so it gives you a good amount of warning time.
