Thank you. That is Indian eagle owl. All my other lenses are collecting dust

How many AF points work with the 2xIII on the 1DxII?

I thought I heard that it only allowed center?

I would be a bit sad if I only had centerpoint with the "800/8DO II IS" on the 7D3.

I saw a Canon list of TCs and lenses for the 6D2, and was shocked to see that the 100-400II at f/8 allowed multiple f/8 AF points, but the 400/DO II IS at f/8 only allowed centerpoint. This is odd, because the DO II is very sharp and AFes so well in general. Maybe it's the diffractive optics, making the slightly OOF areas too sharp and edgy? My 7D2 focuses the DO II at 1120mm f/11 slowly, but perfectly, in Live View.

I'd be happy just to have f/8 at the nine center points, because 9-point does not hunt anywhere near as bad as single-point in poor light or busy backgrounds.

Using 1dx ii. Used 9 center points . Of late i am using only single center point and i feel i am getting more in focus where I want. Initially had lot of apprehensions about bokeh at f8. When you have a clear bg, realized it doesn't matter much. 2x will have issues only in lowlight. But in these parts light is never an issue.

So you are saying that the 400/4DO II IS will use 9-point AF at f/8 with the 2xIII? Any more than the 9 points?

I find a lot of hunting not just in very low light, but in busy scenery like bushes and trees in good light. Even if the center-point box is smaller than the subject, the areas around it can still cause hunting. At f/5.6 on the 7D2, I can use 9-point and hunting goes away, and I watch to see which of the nine-points are used, and it is a simple, fast matter to tap again if the center point doesn't focus. Much less time-consuming than waiting for a hunting lens to come back from Jupiter.

According to the manual with the 1DX II and 400DOII +2XIII combination, all 61 points will work and there will be 21 cross type points available. With the Ext. 2X I/II only nine points with a single central cross type point will function. There is also a note that in low light or with low contrast subjects AF may not be achieved. From my experience the 21 cross type points work reliably in most situations, I've rarely used the non-cross type points so have little feel for their effectiveness.

This has been my experience as well . In lowlight more than the focus, it was getting the right shutter speed that was the issue

Loving the pose on the fox, caught the moment there.

One contribution from me. During summer I'm mostly busy with macro and landscape photography but as fall and winter are approaching the time of my longer lenses will come...

Could not resist trying to capture my wife's hibiscus in the morning light, with raindrops. I think this color is called "Desert Wind" , very prolific bloomer.

This is from a distance of about 10 meters, hand held, slightly cropped. This lens is on my 7dii about 90% of the time, almost always with the 1.4iii extender. Very versatile combination, for my purposes, always handheld.

There was a hummingbird here, just a moment ago, quickly replaced by what I think is a "Skipper" butterfly, feeding on a Lantana blossom.

Very close (20'), but still a considerable crop, center focus point, spot meter, handheld. Will try again tomorrow for the hummer.
