In my testing with EF 100-400 II lens and a bunch of different teleconverters, including the Mark III Canon ones, there was no improvement with any of them over using the lens by itself and resizing. That was using a Canon 5DS. The pixel pitch on the R7 is smaller than with the 5DS, so I would expect no improvement on the R7 either. The lens simply isn't sharp enough to gain an advantage with the TC. But maybe you have a sharper lens than I have. It doesn't appear so, though, from the photos.

Are there sample variations in this lens? I read the first version really suffers from this.

So no gain with the tc at all? I saw some great images on the net even with the 2.0 tc.

I had three different copies of the EF 100-400 v1, all with different levels of sharpness.  The most recent (manufacture date) was the sharpest.  I have a v2, and it's very sharp on the 7dII, even better on the R7.
