I found that the 60-250 was much better at focus without hunting back and forth like the 55-300 does at times. That in itself will give you quicker focus in a lot of situations.

Yeah, that's true but I meant the AF speed for example then when the subject flies towards me and I'm taking photographs of it. Then the AF is as slow as it was in 55-300 and it's not a good thing - before I did buy this objective I though that it should be better than the 55-300 in action photos. But no, it's not, even though it's not hunting back and forth.

On what camera are you using the DA*60-250 on?

I don't know the focus speed of the 55-300, but it is screwdrive and generally the screwdrive lenses are pretty quick. The DA*60-250 is faster at AF than the 50-135, but cannot compare to the DA*300.

Oh sorry, on K-5 II.

In that way I'm thinking too and that's why I'm now wondering that is there a problem on my lens or is this normal thing for this lens.

If anything, record the lens focusing. Show us the view of the focus distance scale moving back and forth - from near to infinity, back, etc. That'll allow other owners of the same lens to judge.

Like:

Side note - I may have mixed up the DA*300 and DA*200. One of them is the focus speed demon. One is not.

Stickl: Things to consider is that the Bigma has a larger zoom range that provides greater flexibility. I cannot comment on AF performance on any of lenses you listed, because I have the non-OS Bigma only. One thing to remember is that even if the Bigma is less sharp at the longer end, it still can resolve more detail than the 55-300 and the 60-250mm because it has a longer focal length. The Bigma is actually pretty sharp, and especially now that I am using my K-5II instead of my K-5, which never focused super accurately with my Bigma. Of course, also the question is how does the sharpness of the 60-250mm @ 250mm and 55-300mm @ 300mm compare to the Bigma @ 250 and 300mm respectively? Many say that the sharpness of the Bigma mainly reduces between 300 and 500mm.

In my brief experience with it I found it to be slower than Sigma HSM but as fast as the screwdrive driven ones. Also I found it rather quick for small adjustments, the opposite from DA* 50-135 and DA* 55 that both needs a start up time.

In the army? Have you seen Heie's work here? It's fantastic and I think he has the 60-250 too!

Anyhow, my main reason for posting is because I wanted to congratulate you on your enormous talent. You have amazing shots in your gallery. Extremely well done.
+1 to that, I'm glad you mentioned it or I probably wouldn't have looked!

When you are shooting like that - a moving subject flying toward you, it is not the lens having problems, it is the camera. Pentax AF is known to not to be able to handle moving objects moving directly toward the camera.

I have the DA* 60-250 and recently had the Sigma 50-500 and I found no difference in focus speed when shooting a static subject. In fact the 60-250 would be quicker to lock since it doesn't have as much focus travel and does not have the weight of the 50-500.

Thanks. Both size- and price-wise that's a camera as a lens accesory!

I had both the 60-250, and Bigma.
55-300 is no competitive to 60-250 and Bigma in IQ and AF speed, so I am not going to commend on it.

60-250 is better in its range in both sharpness and bokeh.
50-500OS is good wide open, excellent when stop down 1-1.5stops. AF speed is faster IMO.

If you need the longer range, Bigma is the way to go.
Remember the f6.3 starting at about 350mm (not quite remember), so it could be a problem if you use it for sport shooting.
