Yes, the Canon EF 400mm f/2.8L is an amazingly fast and sharp lens.

What is the generally-agreed sweet spot on the lens? If it is sharpest at f/2.8, it has to be up there with the very best in angular resolution, making it extremely tele-convertable, about as sharp with a 2x as the 400/4DO II with a 1.4x, but at 2x the pixels-on-subject.

Much of the perceived "problems with TCs" of the past have a lot to do with AF, and AF just isn't a challenge like it used to be. The main issue is how the reporting of the TC affects maximum drive speed, and that's where various TCs can get a bit quirky.

For example, I can make the R5 focus with the Sigma 100-400/5-6.3 extended to 1120/18, and how I configure the TCs and/or tape them affect the max drive speed. Too fast, and there is occasional overshoot; too little and big changes in focus distance take a while to change (but focus is perfect). If we could define the AF drive speeds ourselves with a particular setup, we could probably optimize to our needs. As it stands, the TC attached to the lens is the only factor, and it and the lens together tell the camera, through the lens, what the max drive speed should be (and the body will factor EV level into that, too).

Went to the Lockheed Martin Space & Air Show in Sanford, FL on Sunday. I used the R5 with RF 100-500 and the 1DX Mark 3 with 400mm f/2.8. After reviewing all my images I found the 1DX M3 worked better for me than the R5. I used the mechanical shutter with the R5 and it did okay but if I lost focus it was slow to regain focus.

I've noticed the same thing with the R5 and the 100-500 (as well as the 100-400MKII), when it loses focus it can be really difficult for the lens to get it back fast enough, and I've lost tracking at times because of it.

What I do now when that happens is to let off the focus button and use my thumb to throw the lens to infinity, which is usually where it needs to be for aviation anyway, then that allows the camera to reacquire focus and tracking. I need to do the same thing a lot when using the EF 100mm f/2.8L macro lens as well because it likes to focus behind some subjects and won't sweep through the focus range once it's focused on something.

It's pretty quick now, and while not a perfect solution, since I've started doing it I've rarely had an issue keeping the subject in view. I also added the focus distance meter to the EVF to help me know where the lens is in the range.

Only one weekend yet with the R5, but things are looking good. I got my first "couldn't have done it without the R5" pic. This duck started dunking his head under water, which I knew would lead to sitting up to shake off the water with some flaps. There was no time to focus and recompose or move focus points...the whole thing only lasted a couple of seconds. I just laid down on the ground, hit my back button set to eye detect, and let the camera do the rest. Game changer I think.
