Having seen this initial "landscape" and not feeling quite sure about it, I've been stunned by your recent hibiscus images Michael
(Bob's are amazing too).

If the weather is allowing things to emerge outside where you live Michael, how about some more images that show living things in their environment?
Plus maybe some "classical" style landscapes (since I know you're already going to give us your own distinctive take on things)

Forcalquier, cathédrale Notre Dame du Bourguet.
iPhone and D500 10.5/2.8 DX

I really like the second one, to give a striking impression of what it must have felt like in there Bruno.

I saw this late last night and was impressed Frank.
Looking at it again in a more awake mode today, it looks even better

Formally, today is Norway's Constitution Day -- however we look through that and call it National Day. Which is duly celebrated from sea level to the highest mountain tops -- and beyond (by parachuters and divers).

In the UK, there seems to be less interest in things like this.
I find it refreshing to hear about your National events in Norway Birna.
Plus you always find an interesting angle on them.
I think we've seen similar reports from Netherlands and a few other countries too.

In case you didn't know, at least two NG members are already shooting with this lens.

Look for Grebe images by Anthony on this page
https://nikongear.net/revival/index.php?topic=1938.1425

And Elsid here
https://nikongear.net/revival/index.php?topic=1938.msg199545#msg199545

You'll also see their comments on the practical considerations of using the lens out in the real world in comments on this page

Almost all well-designed lenses at about 100mm and longer (for 24x36) show very flat MTF curves, especially when compared to my beloved wide-angle lenses.  I suppose that compressing the MTF lines for the different line-pair frequencies represents ongoing progress. If these MTF charts are accurate.

Nothing special compared to 500mm f/5.6 PF, but both so excellent that there is no need to be concerned about performance resolution wise. The quality of these long prime lenses is high enough that they are diffraction limited (not talking about the PF effect) near wide open aperture, with front pupil size important for determining maximum resolving power. In planetary astrophotography, it is well established that it is the diameter of high quality optics that determines the optimal maximum magnification to be matched to a specific sensor pixel size.
