Hi Scott
Many thanks for those...............not much to complain about it in regard to image quality in those or the 5D3 performance in the ISO department
How did you find the AF compared to when only using the lens without the TC The reason I so to speak separate the IQ from the AF is that some reports of this combo said the AF suffered somewhat
Oh are these examples the full frame or (slight) crops?
Thanks again for sharing
I have the 200-400, 600v2, sold the 500 v1, 100-400, and 70-200v1. I would not recommend the 100-400 w 1.4x as a normal shooting practice. I think the focus performance is better than my 70-300 IS non L without the 1.4x but comparing my 600v2 with 1.4x on it, it is a tad slower and the iq definitely is decreased.
I think the question is what is your primary purpose that you want to use buy a 100-400 for. If you want a general purpose lens, safari, large animals, bring it with you everywhere, it is the best. My 200-400 has better Iq but much heavier and larger.
If you want a bird shooting lens, you will always be pinned at 400, so you might as well buy the 400/5.6. The iq is better and reportedly takes the 1.4x better and likely will focus faster. See:
http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=113&Camera=453&Sample=0&FLI=8&API=2&LensComp=278&CameraComp=453&SampleComp=0&FLIComp=1&APIComp=0
But the 100-400 w 1.4x performs fairly well on the 5diii. Just not sure about bird shooting.
However, I never bought the 500/5.6 because I shoot more of range of animals - bears, birds, moose and sometimes they come close.
My view is that if you have the 7d and the 100-400, 5diii, 1.4x and was reach limited, I would only use the 5diii if the light was limited (dawn and dusk or cloudy ) and use the 7d 100-400 otherwise. However I have noticed that since buying the 5diii I tend to use the 600/1.4/5diii way more and the 7d/600 less. I only resort to the 7d/1.4/600 when the subject is stationary and the light is good.
I am not sure if that is helpful. Given that I have the 600mm, I have not needed to use the 100-400.
P.S. Not said in the above postings - there were probably 1/10 that were sharp with the boat moving and the whales suddenly appearing, and the changing light conditions.
