Great images. Do you find that the 100-400 works better with the Z AF system than the 500 mm PF, assuming the same AF settings? I think the 100-400 may have two separate AF motors, moving separate groups of lens elements, which might make a difference. Or better synched to the Z AF algorithms. Perhaps that makes it quicker to acquire focus or track focus or perhaps it allows more accurate focus. But would it make a difference on whether the AF system grabs the bird’s body versus its head?Two from yesterday morning...
Both were taken with the Z6II and 100-400. I am still learning how to make the most of the Z system when photographing flight images.
The difference in af performance between the 100-400 and 500PF is striking. I really wish that the prime Z 400S PF, 800S PF, or even 200-600 were available. I am not loving how the 500PF and Z7II are playing together.

I was photographing gulls earlier in the year for practice at the Minnesota Valley National Wildlfe Refuge with my Z7II and 500 mm PF. One thing I noticed is that I had more AF issues as the gulls got closer and took up more of the frame. Of course they are also closer then and the angular motion is faster. But I also wondered if it was partly because the gulls were mostly white and there were fewer contrast differences to focus on the more the body filled the frame? So I wondered if you would find the same results photographing bald eagles, great blue herons or other birds that are largely not white.
I haven’t had a chance to test my new 100-400 mm lens yet. My wife wrapped it up for Christmas and then we had family around through yesterday. Looking forward to trying it soon.
