Summary: Let's look at the Canon 50mm F1.4 lens as an example: http://cweb.canon.jp/ef/lineup/standard/ef50_f14/mtf.html Canon provides MTF Charts for almost all of their lenses on all the country sites that I've seen to date. Here's a link to lens pages on the Canon US Web site: http://www.usa.canon.com/eflenses/lineup/index.html Here's a few more examples from the Canon Japan Web site that use Flash so you can resize them to large sizes for easier viewing: http://cweb.canon.jp/ef/lineup/tele_zoom/ef100_400_f45_56l/mtf.html http://cweb.canon.jp/ef/lineup/super_tele/ef400_f28l/mtf.html Nikon's Japanese Web site does contain MTF Charts for their lenses, although the US site does not seem to. As the lens name is displayed mostly in English, it's not difficult to browse from the below pages.
