Anyone want to explain this one? I scanned it from Digital Photographer magazine (issue #50), a good UK photo mag. It's part of a review on a sigma lens, the 70-200, and they did a similar review on the Canon version (also 70-200). It's funny though, they have a different graph on the Canon review, showing chromatographic aberration (in pixels) for the three RGB colors. I get that graph but not this one. I also don't get why they wouldn't test the same things for each lens for a real comparison?
Maybe another reader can enlighten me on what this graph means.
