Rafael. I agree with Buddy. Heat combined with the amplified distortion of shooting through hot air turbulence and especially shooting across water. The 800mm will show it much more than the 300mm end of the 50-300. I have had similar experience shooting down at the coast in the summer. Very good shots early morning then going south as the sun came overhead. Try with a white towel or put on some light colored lens wraps. I went with a light colored camo wrap from McNett. It relieves the heat some, but of course does nothing for the air distortion.
Guess that is why most other brands of super telephoto lenses are white??
Thanks George and Buddy, I too believe the air distortion and the sun heating the lens combination just ruined my photo-shoot of the USS Zumwalt, good thing I had another lens and camera as the Navy was truly waiting for my pictures. I will try a casual outing where I shield the lens from the sun. I am quite confident it was not hitting the infinity focus, but that there is an interaction of the heated lens and focus sensor that throws the indicator out of whack. Will let you know what I find in my experimental outing..

This is the kind of news folks on this thread are waiting for... a hopeful sign the Z cameras will play nicely with our favorite lenses. Now for reports from those shooting with the Z6 since the sticker price is so much easier to handle. At that price I'd consider buying new. The Z7 I'd likely wait until the used market softens, which could be a few years from now...
Thanks for the heads up on this.
Gpt a Z6 on order at the Nikon store and another at Adorama, also an application to NPS so that I may actually get it. Listing all my equipment and my DoD photographic experiences should qualify me for the Nikon museum.
another 16mm/f3.5 shot - I got my uploads trickling in, as I have still thousands of racing images to go through. This is August 18, early morning on the Dusy Basin Trail, just above the John Muir trail that runs though the valley down low on the right side of the image. The perspective just doesn't do the place justice, as the ground is one big steep granite slab, about 30 degrees slope and water running over it as if somebody turned up a water hose just that morning, no erosion to show that the flow has been there since the ice age glaciers pulled back from the area.
The fisheye is just so amazingly sharp when you shoot it at f/8.0 - I don't think I have any other lens short of my 400/2.8 that comes close to it in sharpness. Every pixel at 100% view on a D810 has valid image information. It takes a D850 or more sensor to really get the most from this glass. It records detail in fisheye view my aging eyes don't see in person on site. It is like coming home to your computer to really see the place where you took the photos.

Perfect term to use
Doing well where I am at (30mi west of Raleigh). Just some wind and a little rain. Heavy rain coming in tonight through Sunday. They are getting hammered on the southern coast, but the Outer Banks seemed to fare well. All things considered. I just saw a message where people are going to be allowed back on the northern sections (north of Oregon Inlet) starting at 7am tomorrow. The southern parts down to Hatteras Village are still closed due to over-wash and sand on Rt 12. DOT said that there did not appear to be any road damage.
It was important to me to figure out what went wrong with the 800mm 5.6 San Diego Bay photoshoot.
Tested the lens and camera this morning and they are fine. This super telephoto at a distance is a challenge to use, but it is not the lens fault, it is the laws of physics, it all goes to hell when the air is hot and hazy and your equipment is hot from the sun.
Here are results I was getting and my tests with crops.
This first photo is technically poor in my opinion, thanks to all the super tele factors at play.
Very glad to hear Rafael that your 800 is well. I have run into that haze above warm water, especially an ocean where it may be churning and evaporating even more from the surface. It was with lesser lenses, but no matter what I did I couldn't get a clear image.
