A bit OT but, increasing number of lens elements seems to be the new normal in camera lenses.

All the latest Nikon telephoto prime lenses have at least 16 elements, the 800mm lens has as many as...

A few scopes have had a foot that fits directly into some smaller Manfrotto video heads. Might be handy, but the Harpia is too long and heavy to be a good match to those quite small heads in my...

Harpia scope will probably be similar to the photoscope (see photo below) so there will be more elements in there compared to a conventional spotting scope. Coatings and glass are so good these days...

Just a thought, Zeiss Victory 8X25 FL Pocket. Eye relief and handling seem to be better than the average pocket bins and close to a 8x32 (according to some members here) and still very lightweight....

'Effective aperture' means the smallest aperture in the optical system.
So there will be no effect if your eye pupil is smaller than the exit pupil (4 mm). In daylight it will most likely be. But who...

5:
I get at least 80% (measured, not estimated) of the 7x42 FL FOV sharp (with some refocus as it's not completely flat). The rest of the 150m FOV is still a help when following fast moving birds at...

Ok, thanks for clearing that out.
I don't think I have seen anything about that anywhere,
so I probably would take it with a grain of salt.

Perhaps, but it will be shorter.
As an example the "classic" Tokina 500mm/f5.6 (95mm filter thread) weighs 2240g.
The 300/4 PF is aprox. 45% lighter than the older AF-S 300/4.
2240x0.55 = 1250g.

1250g at the most and
the 500mm + D500/D850 would be perfect for walk-around purposes without monopod. (Which I don't think the 200-500mm really is.)
But the VR got to be as good.
