Realistic subject distance remains a dominant factor determining image quality using TC, a F or Z TC2 especially.
Fyi There're more 400 f4.5S examples
here
This right here is so very true, much more prevalent in my dslr F mounts.
The quality is still impressive from the Z TC2x.
Following are three long distance shots with the TC2x. This cabin is 4,624' from where I was shooting the birds.
Resting the lens on a window sill of the birding blind.
The first two are unedited, (except for downsizing with FastStone) jpg's right out of camera.
The second photo was shot in DX mode, and the third is an edited crop from the DX shot.
I have no clue why the site is changing the shutter speed from the exif. Should be 1/320th
