Tamron 70-200 on K-1 (either version)

I am afraid you are limited by Pentax AF system here. While K1 II will definitely improve your AF speed and accuracy, it will never be in the same league as Sony (no experience with Canon/Nikon). The difference is really night and day. As much as I like Pentax IQ and colors, I am planning to replace my Pentax Tammy with smaller and lighter Tamron 70-180/2.8 for my A7R3.

Interesting that you say that...

A good friend who is a professional photographer has shot Nikon DSLRs for years, but I didn't realize that she had recently begun switching over to Sony mirrorless. When I floated my idea of getting a D7500 and a Sigma or Nikkor 70-200/2.8, she suggested I take a good look at Sony mirrorless. It's been a while since I've even looked at other systems, so I was still thinking that mirrorless AF was sluggish. Apparently that has drastically changed in the last couple of years. I stopped by Best Buy yesterday just to get my hands on a few mirrorless cameras, and I could not believe how small they were. Long story short, I've now concluded that if I end up going a different route than Pentax, I would probably get an A6400 and the Tamron 70-180. I'm also attracted by Sony's pancake 20mm - I think I could put that on the A6400 and carry it in the back pocket on my cycling jersey. I would love to have a quality camera with me while biking, rather than settling for my cell phone.

So I'm leaning heavily toward that option right now. I would still keep my K-3 and collection of Pentax lenses for a lot of my shooting that doesn't demand fast AF. I truly love a lot about Pentax... just not the AF. But I'm not alone there, for sure.
