Although the last two were very appealing (600mm) the image quality of the first has made up my mind, Seeing images at 300mm, comparing prime lens to the 100-400 and the other two, well it was not really comparable. The 100-400L was more expensive, and it did hurt but the images it brings, worth every dime payed.
I have both the 100-400mm II (had 2 copies) and the Sigma 150-600mm C. You might have done "research", but I use both extensively. My Sigma has fantastic IQ at 600mm, and knocks the 100-400 + 1.4xTC for six. It doesn't focus as fast as the Canon, but it locks on well. And it is close to the native 100-400 at shorter focal lengths. Canon will find it difficult to beat.
That is not what Brian at TDP found.

I missed out on buying the Sigma earlier on precisely because of TDP in particular and other sites that test just one copy at just one particular distance using just one method. It was only after I borrowed one from the local dealer and found it so good that I bought it. The only reliable site for me is Lensrentals who test 10 samples of each lens on the very best equipment focussed at infinity - perfect for telephotos.
TDP and other sites should have message in capital letters on each review.
GOVERNMENT HEALTH WARNING - WE TEST ONLY ONE COPY, YOURS MIGHT BE MUCH WORSE OR MUCH BETTER THAN OURS.
Don Haines said:The rumor is that Canon is working on a supertelephoto zoom. It does not start if it is low or high cost, and it does not state the technologies used. It could be anything from an economy lens at F8 to a DO 400-800 F5.6 with a built in 1.4X teleconverter.... Nothing is ruled out!

arbitrage said:600/5.6 on the long end is not going to happen so lets just rule that out. Because that would give us a front element as big as the 300/2.8. Canon can do that but it will be a big lens and heavy and expensive.
