Excellent set Turbo. I like everything about these images. Composition, color, sharpness, and rendering are first rate. Looks like the 70-200 is an excellent lens for the Z6. It also look like you and the Z6 are made for each other.
No sense telling the competition that it is a Nikon not a Sony. Let them figure it out...
Any shots with Z mount 50mm lens? I am trying to decide if I want one, but what I see on flickr with this lens is quite underwhelming. I particularly would like to see portrait shots to see how it renders out of focus area and overall isolation of the subject from the background
Just picked up a new Tamron 70-200 G2. Fantastic lens but ran into an issue today I thought others might want to know about.
The G2 has a unique VC feature that allows you to select whether the VC is always stabilizing (VC Mode 1, helps for VF framing) or if it only stabilizes during an exposure (VC Mode 3). The latter results in a shakier VF image but saves battery because VC engages for a much shorter period of time. The Tamron manual also hints Mode 3 may yield better stabilization - it says the following about it: "Mode that prioritizes compensation effects, compensating only at the moment the shutter is released."
While trying out the various VC modes I noticed image ghosting when using VC Mode 3 in combination with the Z6's fully electronic shutter. The issue doesn't occur in VC Mode 1, and also doesn't occur in VC Mode 3 using the mechanical shutter (EFCS).
Note this isn't typical image blur from a marginally-stabilized image but instead what appears to be two positions of the VC element captured in a single exposure.
At first I thought the issue might be related to the ES slower readout speed, but that seems unlikely considering it doesn't occur in VC Mode 1 and also because the ghosting is both horizontal and vertical (horizontal means it's not a rolling-shutter artifact).
I'm guessing the issue is caused by a timing mismatch in the Tamron firmware for VC Mode 3. It has to detect when an exposure is starting to know when to engage the VC - it appears the timing of that detection is a bit off when the electronic shutter is used.
I first noticed this when shooting at very slow shutter speeds (1/8). I see it up through 1/60. Af 1/125 it's pretty much gone.
I'm using the latest 70-200 G2 firmware (Version 2), which corrects the aperture compatibility issue with the Z.
I would be interested to see if this happens on the D850, which also has an Electronic Shutter. Can anyone with a D850 who owns the 70-200 G2 give this a try?

Hmm, I was thinking about swapping out my 70-200 f2.8E FL for the Tammy G2 (in part because my latest lens purchase - the latest 17-35 f2.8-4 OSD is pretty solid), so this is a little troubling...
If I recall correctly you're not near Seattle, but if you are, I have a D850 and would be happy to do a little testing.
At the very least, I can test my Z7 with the Nikon 70-200 f2.8E to see if it's something to do with the lens or the body.

Thanks. Turbodude has the G2 and confirmed that the ghosting occurs on his Z6 but does not occur on his D850.
Have had the Z6 for a couple of weeks but haven't had a ton of chances to shoot with it. So far so good though, I was surprised that it's basically the same size as my Pany G9 (which is a good thing).
The first couple of my dog River (my dogs usually end up being the 1st models for new equipment )was just after I picked up an inexpensive Godox flash (can't beat the price).
. Balmy day. I have some mixed opinions on the combo.....
