Agree with all above, and I still have a 200mm 1.8. I used it all the time with a 1.4 and 2x extenders in my earlier days for football etc. Used to get some cracking images when coupled to my 1D mk1 and 10D.
Its been retired due to auto focus motor problems and lock ups. It sits in its box under the stairs awaiting repair as were told by Lehmans it was unrepairable as no spares are available, (unless anyone knows who can fix it out there).
I would love to use it again if just only for the indoor stuff. Would recommend, but the spares problems would be an issue, but not if you're looking at a 200mm F2.
