I was using a 1DX body that did not have the lens correction profiles loaded. The JPGs had very much a spotlight look to them with vignetting across a majority of the frame. The raw files looked fine once lens correction was applied in LR, but for this assignment I was given both the body and the lens and had to shoot JPG for the client. I was pretty disappointed. Having shot the Cotton Bowl with the same combo and in raw, it was much better. I'm just not a fan of a $11k lens requiring so much digital manipulation to be consistent across the frame.

Can you give an example or quantify your findings? It could be interesting to see.
As far as I know the vignetting is slightly over 1 full stop in the extreme corners @400mm f/4, and @560mm f/5.6.

OK it is clearly visible. I'm also inclined to feel that the cluster of silvery helmets at the center makes it appear as though the corners were even darker.
I'm no big fan of added vignette (in post) to most photos, but at the same time I find that the natural vignetting and distortions from a lens is part of its charm and characteristics. Here, for your purpose, I understand the removed vignette, and I would most likely do the same. (or have the body set up to apply those corrections in camera)
I have gone through a number of my images with the 200-400 to critically asses vignetting. I have not measured it accurately, but if I had to give a number I would say that, wide open, it´s about 1 stop.Andrewccm said:I've used the 200-400 several times and most recently to cover the college football championship.
