I recently sold my 24-70/2.8, which I've had for about five or six years. (Though well cared for and maintained by Canon, I usually replace lenses every 5-10 years because of general wear and tear and the fact that they become harder to calibrate. The same happened with my 50/1.4 and 85/1.8.) Anyway, I went on line to search for the best pricing on the lens. I few references popped up for things like the Sigma 24-70, so I thought I'd compare MTF charts on the lenses. I went to Canon USA and could not fins a working page on the 24-70. Though it comes up in a search on Canon's site, there's no actual page. Just blank. I tried three different browsers thinking that it might be some quirk in the coding. Same result in Explorer, Firefox and Chrome.
I can't find anything concrete (or even vaguely rumored) on the net. Anyone heard anything or experienced the same thing?
