I've always been curious about these covers.....do they project in wet conditions or just soak up the water and provide longer exposure? I can see the benefit for the bumps that occur to gear.
Personally I use those on bigger lenses to protect from scrapes and bumps. It's made from nylon but it's still made from multiple pieces, so it doesn't make the weather sealing any better. If it gets soaked, the removal process is pretty straightforward.
Most of the images appear to be taken with the Z9 body. Is anyone using this lens on a Z7 body and if so how well does it perform in terms of focus acquisition for bif?

Today. Got to see my 1st green heron during my sunset outing.
Very nice pictures.
I wonder if they were cropped.
I think that we should always indicate the amount of cropping, if any.
P.S.: to calculate the crop % here is the formula:
-100x[(final image Mpix) - (sensor Mpix)]/(sensor Mpix)
or (it's the same)
100x[(sensor Mpix) - (final image Mpix)]/(sensor Mpix)

Some of those are in DX mode (my setup allows me to switch on the fly). I don't think we should 'always' indicate the crop - what's next? Always provide raw files? It's the final result that matters.

Nobody asked the raw files. This is a technical (Gear-talk) forum, and it could be helpful to know what we can do with a given lens with and without the need to crop an image. In particular for pictures taken with macro and telephoto lenses. Anyway, I have enough experience with nature photography to understand when pictures have been cropped
Have had a backlog of undeveloped files that I am catching up on so apologies for monopolising the thread! Here a landing sequence of an Australasian Gannet in dying light at the Muriwai colony, west of Auckland, NZ. Exactly 0.3 seconds elapses during the sequence and yes, they are all nuts-on sharp. Bare lens, processed from lossless raw in LR, EXIF data intact. Hope these are not too large. Cropped?
I finally got mine, and I took some shots yesterday.
As an owner of 100-400s, which I sold to get this lens, all I can say, no regrets.
The only thing I'll miss is MFD, I used the lens 99% at 400%, so flexibility isn't big deal to me.
This lens is lighter, sharper, AF is faster, contrast and saturation are better wide open, especially shooting with back light.
So far, I love it!
One thing I noticed, the focus ring isn't as tight as on 100-400s, it's got little bit of axial play.
Is this Japan vs China make, or it's matter of design, hard to say.
The 100-400s was perfect, at least my copy.
Both images are with Z7II, at F4.5, 1/2000, 1st one ISO90, 2nd one ISO100, cropped about 80%.
It's amazing how F4.5 drops ISO down, it feels really good.
These are nice shots of a unique species Luke. Your first picture answers a huge question for me. Specifically, how does the 400m f4.5 handle backlit specular highlights. To my eyes, it exhibits some of the same issues I see with the 500mm PF. One of my preferred locations for shorebird photography is almost always a backlit situation, as these birds are only visible in the morning. With the sun rising towards the east, I am stuck with backlit conditions. I have found this to be one of the few weaknesses of the 500PF. The rough bokeh in these highlights is virtually identical to what the 500PF would do.
Would you mind disclosing... what was the aperture in those two turnstone images?...
I don't think I have experienced roughness in the bokeh balls to that extent. I love to shoot backlit at the sea, both east and west coast, morning and evening (mild to extreme):
