Results of my new Canon 600mm f/4 III with the 1.4x III converter to make it 840mm

In the first one there is no detail around the eye because it it over exposed. The key to using manual exposure is to expose to retain detail in the brightest part of the image that you still want detail. That first image os a good case for auto exposure and highlight tone priority where the camera will automatically try to protect the highlights.
does this feature make the camera meter for the highlights so it wont ever overexpose?

I don't find it to be useful. By the way, I have seen wood ducks in captivity and I can't see any detail in the white area around the eyes then either.
I googled "female wood duck images" and can see lots of detail around the eyes. It looks like the white areas are bleached as privatebydesign suggests. And you can see that for sure by downloading the image and adjusting gamma in PS.

On my 600/4 II, the 2xIII does give acceptable (to me) results, although there is a slight decrement in sharpness compared to the 1.4xIII.
I'd agree. The 2XIII works better on the 600 II than it would say the 70-200. Focusing does slow down but for stationary objects the image quality is good with it. I was amazed they shaved the weight they did off the III. The 600II is awkward to get out of bags and mount. Much better when on a gimbal. I used the 600II on safari and it was a workout moving it up and down. A high price though for that weightloss on the 600III

Here are a few more I did recently from a floating blind with the 600mm and 1.4x

That made me laugh!

EF 600mm USM 6.05kg
EF 600mm USM IS 5.36kg
EF 600mm USM IS II 3.92kg

And to think we used to shoot with the old 6kg anchor!

I'm sure the III is very nice to manoeuvre with its redistributed elements, but the II itself was a flyweight amongst superteles.

Lot of computer workers nowadays , and those mostly can afford 600mm as hobby stuff :)
