Indeed! And I was wondering whether the new 100-400 would be practical for photographing sunsets.Edit: Just seen that TDP has the image quality data on its site. There seems nothing between the 5.6 400 and the vii
Well, in the corners, the 5.6 400 L looks better to my eyes and this becomes even more pronounced if you compare both lenses with the 2xIII attached:
However, I expect that in real life and @ 800 mm/f 11 you will have more keepers with the zoom than with the prime most of the time due to the IS, unless you have reaaaly good light.
I'm not so sure. The 400 prime has better light transmission than the new 100-400. 21 lens elements vs 7 on the prime. IS may help but it doesn't help in every situation. It's the zoom trade off.
For example: My 70-200 IS 2.8 II not so much! My 300mm f/4L (non-IS) on the other hand rocks...
(And I am not talking about magnification obviously...)
