Well, I think I probably do have "proof" (which I will try to find tomorrow!) of what can happen with the PLM on the K-3 and K-3 II in the form of shots taken at a Suttleworth airshow earlier this year, i.e. I used spot focus to focus on low-flying moving aircraft and then the PLM uddenly focuses "anywhere" and it then takes a lot of time & effort to get it accurately focusing back on the plane - whereas that didn't happen anywhere near so much with the Sigma 100-300 F4 on both K-3 bodies.

Thus, whilst I will generally use the PLM on the K-30 / "K-50", I will use that Sigma (and its "little brother" the 70-200 F2.8) on the K-3 / K-3 II for challenging situations like that mentioned above.
I have heard that 9 focus points is the way to go for airshows and certain Bird In Flight shooting.

I need to look at that. I'm pretty sure my U1 Sports setting (TAv, 1/1250th, f/7.1, etc) is on center point autofocus. That was what I used for my rocket shoot.

Hard to get the edge for contrast with only the one point when dealing with a fast mover. That is why I think 9 would be best for using the PLM in that situation.

I think I was already on 9 point select. I just picked up the K-3ii, set it on my U1 sports setting, and it has a red point in the center, surrounded by eight pink points. Maybe I'll try the 27 point expanded area AF?

I was just going off of what I read here in a chart someone had made on focus for differing situations and logically the 9 points made sense, even though I normally use single point on BIF.

An additional point/thought:

From my experience, I'm fairly convinced that the type of background behind the target plane/BIF seems have quite an effect on whether the PLM keeps focus lock or loses it - if the background is fairly plain and there is a good contrast between the target and the background then is a reasonably good chance it will maintain focus lock, whereas if there is not good contrast between them then the chances of that are much lower.

Callistemons (bottlebrush) with the K-S2 + DA 55-300 PLM

70mm. f8, 1/125th, 400 ISO.


63mm. f9, 1/200th, ISO 1000.


Greg's made the point before: the lens is excellent at these wider focal lengths.
