I’ve been testing the new Canon Rebel XSi. The image quality thus far is impressive. Below are a few in-camera JPEG samples taken throughout the range of ISOs available. You may click on each photo to view the original image at 100%. Additionally, you can see more sample images in this Flickr set (Full EXIF is available). More news and reviews are available on the Canon Rebel XSi Reviews and Resources page.
ISO 100
ISO 200
ISO 400
ISO 800
ISO 1600
I would probably like to see pic taken in low light condition with high ISO, cause noise is much bigger then.
