I'm taking mine along to an airshow tomorrow with the K-3 and Sigma 100-300mm f4 so hoping it will all work ok. Taking the Sigma 50-500mm OS as well though just incase.
Thanks Mike.
I had a Sigma 100-300 a while back. That was a fine lens, so good luck with the setup.
Post some pics when you return.

Edit:
So ... after the firmware update, which really went well, I took some various shots at different distances.
Results: great! (No pictures to post yet ... soon.)
I found that I had to crank the EV up to +0.7 though. I was shooting in TAv as usual with K5 plus DA*300/4. Normal I would think?
Interestingly, the AF was snappier especially for distant objects.
