You wrote in another thread where you were arguing with GMC: "I leave it as an exercise to the reader to search the web for information how much shorter the 70-200 F/2.8 L IS II gets at nearest focus distance. It's all there for anyone to read.".
During my searching for that information, I read a lot of articles about lens design, including some very illuminating ones about Nikon 80-400 zooms, showing how different designs give different changes in focal length on focussing. But, I could not find the information about the 70-200mm, perhaps because of my ineptitude. As the tone of your comment implies that you have that data, please put me out of my misery and post the right link.
