I originally posted about that lens here:

This was in 2019.  I have since graduated and found a job.

Through some luck, I got a copy for AUD 2000.  It had some fungus spots.  Our local Nikon service centre determined that the fungus was growing inside a cemented doublet (the large front element).

The repair quote was $3700. :'(  The fungus was not too bad so I am just going to use it as is.

Look at how massive this thing is.

It is just barely within my hand-holding limits after my left arm had to undergo surgery.
The focusing is incredibly fast and accurate on my Z8.  It feels way faster and a lot more accurate than my 500mm PF.
I tried it with the TC800-1.25E ED, no loss in image quality or AF speed was observed.  Image quality loss with a 2x TC is noticeable but acceptable.  AF is still fast, it still feels faster than my 500mm PF.  I might sell both of my PF lenses because of this acquisition.

 
Here are some photos I took.  It works so well for wildlife where the surrounding environment can be incorporated into the shot.

With the 2x TC.



I love the results.  Even messy backgrounds melt away.  This makes me want to get the 400mm F2.8 TC or the upcoming Z-mount 120-300mm which no doubt has a TC built-in too.

Sorry for your bother.  I should have added that "if it were my image."

That said, the nit-picked version feels more compositionally stable for me.

In the Background we have these windmills where the tilt most was clearly visible

Beautiful color and atmosphere.  As nitpicker myself, I couldn't resist correction of the tilt, but the image is too good to dismiss.
