I think they took the samples from the edge of a full resolution image. One difference between good and cheap lenses is that the center of the image will always be good, while on the edges more and more distortion might happen in the cheap lenses. It's possible these images were perfectly in focus on the focuspoint.
- tanzam75 13y agoThose are nearly full-sensor images. If you download the supplemental materials, the large images are all 3492 x 2205. That's 7.7 megapixels -- and the Canon 40D is listed as a 10.1 megapixel-camera. They shot the photos with a hand-made, one-element lens. This is a very bad lens. The photos may look like they're out-of-focus, but they're actually in-focus. (The width of lines does not change after the processing.) They just have an extreme amount of diffusion, chromatic aberration, and all sorts of other distortions.
