I'd be interested to see a comparison when these are out.
100-400L II at 400mm and f/5.6 upresed 50% compared to Tamron 150-600 at 600mm and f/6.3.
100-400L II + 1.4x TC III at 560mm and f/8 compared to Tamron 150-600 at 600mm and f/8.
My prediction as that both would be a near tie, except the Canon will have less CA and faster focusing on the first test.
my prediction is that the first comparison would put the tamron far ahead for total detail, 200mm is an insane amount to make up for, the tamron would have to pale even compared to a coke bottle for that to be true
now in the second case maybe it would be about a tie? who knows or even better?
Results are mixed, see for yourself:
The Tamron loses a lot of quality from 500mm to 600mm.
Though, as has been mentioned, the center sharpness remains and for 'most' instances with this lens, the point of interest will be reasonably centered and not offset overly far. As always, a compromise, though in this case one that 'generally' will work. It is by far not a perfect tele, but for the price it is more-or-less astounding.
