I must admit, 'though, that all of my lenses are Canon, and I bought the 300 f4 L IS, which is a more portable lens than any f2.8, of a similar focal length, and will still auto-focus with a 2X TC on an EOS3, if not as quickly. The zoom is f5.6 at 300mm, so will only auto-focus with a 1.4X TC, which will give a 400mm f8, compared with the 100-400 Ls f5.6. I know, that one wasn't in the original question. It will be interesting to see how the 70-300 DO IS compares with the very popular 100-400L for optical quality, and sales. ----------------------------------------------------------- I have noted that every review I have seen has seemed to be of the opinion that the only competitor to the 120-300mm sigma is the 300/2.8L. And some are iffy on that. Kind of scary actually. I do wonder what the actual focal length or aperture is. It is not physically possible that it is actually 300mm f2.8 (105mm filter... means smaller that 105mm aperture). What I really want is a general long telephoto, that is not a push pull (abhor those). I would like speed or IS. I want it for wildlife and racing. I am not really worried about weight (the 100-400mm IS did not phase me). But, compact nice does have it's advantages. I will not be able to justify two long telephotos. So I really need one that can be used in both. I have both the 1.4x and 2x Kenko Pro 300 Tele Plus converters.
