My only argument with absolute statements like this is they seem to focus on birds, primarily BIF which can test a cameras and lenses ability to keep a subject in focus, but there are many other forms of wildlife and different situations. As an example, I shoot a lot of black bear which tend to be in shaded forest cover, lack contrast on the face/eyes, and quite often have blades of grass, twigs, or branches nearby, and require higher ISO. This can also be tricky for AF systems in a different way even though the bear tends to move slow. What works best for BIF might not work best here. Steve Matthies mentioned the bison in the snow was better handled by the Z9. Maybe you or
@arbitrage have tested on other wildlife like black bear with all cameras and are taking it into consideration. As black bear are in hibernation I haven’t been able to and haven’t seen any comparisons. I have seen the Z9 detect the eyes of fish, lizards, birds, raccoons, squirrels, and birds, as well as the bodies of dolphins. I’m sure the best cameras do well in most of these situations, but not seeing comparisons. If you have tested, or even better compared the top cameras with other subjects, please share your findings as I am not a birder and am curious. If not, I‘d appreciate it if you could add “best for birds” to the comment. I’m not trying to disrespectful, just not into birds as much as most others here.
