The 400/5.6L was my main birding lens for over a decade. The 800/11 has been my main EIF (eagles in flight) lens beside the 100-500 for three seasons. While the 400 was very good it was not at the 800/11 level, perhaps not that far behind. I had the EF 2X II, but never used it because it was simply bad. Perhaps the v.III would perform better, but it will never bring the 400/5.6L up to the 800/11 level. It might be good enough though.
I have only experience with the one 400 I had which did well on the 18Mp crop sensors of the day. The 800/11 does very well on the much more demanding 32.5Mp sensor of the R7.

My 800 arrived this morning. Can't wait to get home from work and pop it on my R100

It's been cloudy, so I haven't had the chance to point the 800 skyward, but did grab a couple of pigeons on my garage roof. They were roughly 150' away. These are 33% crops with about 5 f/stops of IS. I'll definitely need my tripod for better shots.

You can't fix blur, but you can certainly reduce noise, so what was the point of shooting at ISO 200, instead of 800 or 1600?

I wanted to see how long I could handhold the lens before shake set in since I drink 2 to 3 cups of coffee a day, so that was my reasoning. I thought it was 100, not 200 until after I looked at the exif.

This lens seems to be a real bargain, at less than a dollar a millimeter...

Of all of Canon's "way too slow to be useful" RF lenses, this one impresses me the most.

This parent Killdeer is pretending to have an injured wing in order to draw predators away from its chick that is only days old and unable to fly yet.
