This afternoon, I put the 20D to the test during a visit to the Smithsonian Air & Space Museum. The SmugMug photo album shows off some of I snapped today. These were all taken without flash in automatic mode and have been posted with no adjustment or cropping. I shot all images at fine-quality JPEG, or about 8.2 megapixels. Detail on the Capitol building, shot a good half a mile or more away, is excellent. Warning this is a hefty, 3MB-plus image.
