Originally posted by GeneV Have you used a D500? I would have agreed with you until I did. There is zero advantage to any Pentax AF over that model IMO. Partly, it is the speed of SDM or lack threreof. The D500 and the Sony A7RIII give the photographer little reason to use anything but AFC, even for stationary subjects. Catching a BIF is so much easier, it feels like cheating.
Have you used the DA 55-300 PLM? Or a Tamron 300 2.8?
I could say that the speed AF.s locks focus with those lenses makes tracking pretty un-necessary. But where I live the bush is always so close BiFs is really not a thing. Yet when I get the chance I do fine.
I'm still not seeing any images.
I have no idea if you're getting images I can't. or that I'd even want, my own personal thought is that most BiF images are lacking in detail. So I actually don't know if you're keeping images I wouldn't toss.
Last time I went through this with Dan Renteria he didn't post a single image I couldn't have done with my K-3. Convince me. Words are cheap.
Or is they a "just take my word for it" kind of thing?
Like I'm going to spend thousands of dollars based on that?
I'm looking for information, not opinion.
After all, you're getting images I can't is based on you possibly not shooting the way I do. It's quite possible the superiority of your D500 is dependant on how you shoot and irrelevant to me. Although I have to say, the biggest disadvantage to a K-3 is the FPS gets cut in half when tracking. Given that every system takes more than twice as long as a K-3 to lock focus with tracking implemented compared to a K-3 in AF.s , I have no way of evaluating whether a D500 would get me shots or cost me shots
Originally posted by GeneV For me personally, I have all the photos of birds around me on branches I need. I want to catch them in motion.

I'm not seeing any evidence you succeed in catching anything. This sounds like a snob post, and there's nothing there to suggest different. Just some guy saying "my camera is better than yours" I got over stuff like that when I was five years old arguing "my father is smarter than yours". I shoot next to people shooting all kinds of different cameras. Reslts are not always as your post would suggest. Although I'm quite happy to acknowledge you have a personal preference fo the D500. No doubt it's better for you, even if we can't tell what that means in terms of image quality. If it makes you happy go with it.
