Speaking of bears, here's one. Camera estimates the focusing distance was 88 meters. Most people are surprised how much focal length is required to get an bird or mammal to be a decent size in the frame. Still had to do plenty of cropping on this.
This common garden bird served as a convenient test subject after I MFA'ed my 5D3. Placement of focus seems precise after a +12 MFA, especially considering the very thin DOF at less than 6 m shooting distance.
Yellow-vented Bulbul(Pycnonotus goiavier)
5D MIII+ 400 f2.8 IS + 2x TC II, 800mm, f/5.6, ISO 1250, 1/250 sec, manual exposure in available light, AI servo, 475B + 516 support, uncropped full frame resized to 1500x1000, 5.63 m distance.

Maybe a silly question, but did you do the AFMA with or without the extender? I have a 5D3 and a 400/2.8L IS as well and mine needed a +12 adjustment too, but I haven't checked with an extender mounted and I wonder if it makes any difference.
You need to do the MA both with and without the TC and both values will be stored and applied appropriately for whichever you have mounted. The value with and without TC will usually be different.

+1.
I did MFA for the naked lens, with a 1.4x TC and with a 2x TC. The +12 MFA was for the 2x TC.

Excellent portrait, Peter.... love the golden OOF water in the BG!
Interestingly, this shot shows that the 2x III isn't immune to the odd bokeh we discussed sometime ago. The forking branches in the BG both have the weird double outline along the edges.This is the first time I saw this phenom at your shots.

And I thought the OOF water was just swift moving...it's an interesting, pleasant effect, almost looks like wood carving
Another great shot Peter! One cool thing not usually seen in your images are your pijun's webbed feet in sharp detail, very nice

Romy, I've seen it too in this shot, although I do not get that very often. Nothing we can do about that, I am afraid.

I love using the 2X III with my 300/2.8L IS II. It takes little space in the backpack, the combo is relatively easy to hand hold, and it's relatively more affordable than a 600. Here's a shot from this morning. More here - all the obvious long FL shots were done with the 300 + 2X.

Well, having accepted that this phenom can happen with a wide open 2x II (it virtually disappears at 2/3 stop from WO, or smaller Av), I usually try to frame the subject such that elements with sharp lines will be as near to parallel to the focus plane as possible.
Of course, we can't always do that in the field at skittish subjects. So if the shot is made and the phenom happens, there are several techniques in PP to reduce its effect. This will depend upon an individual's taste on how far can one alter elements of the bird image.
Here's a sample routine to mitigate the effect - I selected the affected branches in the foreground and background and applied a mild selective blur.
Shooting info - Canon 1D MIV + 400 2.8 IS + Canon 2x TC II, 800 mm, f/5.6, ISO 1600, 1/320 sec, 475B/516 support, manual exposure in available light, near full frame.

Great shot Jess, and a very difficult one to make.
