Today I decided to go back to my "studio" and try the Mk IV paired with the 100-400L II to see how it compares to the 7D II and 100-400L II combo. Hard to tell They both perform very satisfactory. May be the Mk IV shows a better sharpness. May be.
I'm cross posting this post in the Canon Forum (trying this new feature)
For those interested in the pics taken with the same lens paired with a 7D II they can be check out here: https://www.fredmiranda.com/forum/topic/1336487

I feel yesterday's set appeared a bit more detailed yet there are so many variables when shooting in the field I can only say that both setups work very well. Super photos in any case Socrate
Great shots Socrate. Are any of the in-flight shots taken at 400mm and f5.6? I'm curious to compare with the 400 5.6 prime in quality and focus speed. Can you comment on that?
Really nice shots. I would love to see some controlled focal length limited tests of the 1DX, 7DM2, and 1DIV. My guess is the 7D2 would win unless it was at a crazy ISO but I'm not sure...
Another great set. Looks like the 1D4 and 7D2 are very close to each other. Probably comes down to how the AF performs and maybe some operational preferences. Also the extra reach of the 7D2 would likely help in some situations. What I can say is that 100-400II is now on my shopping list. Still not sure about the 7D2.

Thanks, Mark.These are taken all at f/8 and around 300mm for the sanderlings and 250mm for the Willets. I would say the focus speed of the 1-400 II is pretty close to that of the 400/5.6 and better than the old 1-400 where the focus seems to hesitate some times.
Socrate
Okay, thanks Socrate. The new 100-400 II is tempting to me, but only if it could match the 400 5.6 AF speed at 400mm. So I guess I'll stick with the prime.
Nice, images and thank you as I'd be using this on my 1D4 so it's really nice to see. Looks like the new 100-400 is a worthy lens if one uses those focal lengths, which I do. May I ask how much processing/sharpening was necessary? I am not asking as an insult or anything of the sort - I had the old lens and I needed to "massage" my images quite a bit, especially those shot at 400 in crappy light!
Thanks again - SHaron

great set Socrate. These appear sharper than the 7D II shot thread imo. The mark IV IF's also appear to have better separation from the BGD, especially willet and piper shots, maybe aperture settings were different as well ?
They both perform very satisfactory. May be the Mk IV shows a better sharpness. May be.
