Canon Powershot S80

Canon PowerShot S90 10MP Digital Camera with 3.8x Wide Angle ...

I bought this camera on 10/9, which is the first day it was available here in Kansas City. I have already taken a couple hundred shots with it comparing images side by side with my G10 at various settings. This review is of my initial impression based on the short time that I have had it. I was anxiously awaiting the release of this camera. I own a Nikon D90 DSLR, but there are many times when I prefer to just take a compact. In the past the Canon G10 has served that purpose, but the S90 boasts improved low-light performance and smaller size.

The first thing I wanted to test was image quality and noise at high ISO settings. Most photography hobbyists and pros know that low light performance is the number one factor influencing camera and lens prices. This is the main reason an f/2.8 zoom lens costs 3-5 times as much as an f/3.5-5.6 zoom. The S90 performs superbly in this regard. RAW images from the S90 set at ISO 800 were equal to or better than RAW images from the G10 set at ISO400. Both luminance and chrominance noise were lower in the S90 images. This represents a 1 stop improvement, which is what I was hoping for. These comparisons were made with all noise reduction disabled in camera and in the DPP software. I tested all other ISOs and found the S90 to be better at all ISO settings above 100 and the 2 cameras demonstrated equal IQ at the base ISOs of 80 and 100.
