Yes, its great.

Without going into comparisons about resolution Canon lenses fit Pentax bodies badly. That's the main reason not to get one. And no, Pentax is NOT cheap.
Compared to third party lenses it seems the focusing of this works a little bit better (again, on Pentax) than the competition. It actually works quite well. The samples below were made with K-7. No PP, just to excuse some bleakness.
Last point - weather seal. Really a must have for a typical outdoor lens.

I believe this lens is not so popular because it's neither dog nor cat...
@250 it's not quite long enough for many wildlife shooters, @f4 it's not quite fast enough for many portrait shooters. It's not small, neither light... it's stuck somewhere in between 50-135 which is f2.8 and smaller/lighter, doesn't zoom out and is considered fantastic portrait lens, and 300/4 which is roughly the same size as 60-250 at it's shortest, I assume lighter, and 50mm longer at the same speed....

my 2p
The 300/4 also offers better magnification than the 60-250/4: 1:4 vs. 1:6.7.

Instead of spending on the DA*50-135, DA*200 and DA*300, you could conceivably buy just one lens to roughly cover the range in the DA*60-250mm. I've tried it and I think it has a very versatile zoom range and performance is actually pretty good. I think it should be bench marked against something like the Canon 70-200 f/4.

Thank you. The jigging was making me more mental than I usually am.
Flashing lights do the same thing to me. I suspect I may be slightly epileptic, as this sort of thing has always caused me to go off.

A macro lens would be a better solution (1:1).
The downside of the 300/4 is that it doesn't have a 150mm setting (for example).
I don't think I'd be basing a purchase decision of a long telephoto on image magnification when there are so may better options out there.

I find my 300 gets very little use these days, the 60-250 is the better lens and with the DSLR, the 300 just doesn't seem to be the right focal length most of the time, either being too short or too long.

Depends on what you're trying to do. I want something I can use for distant subjects and also for closer but smaller subjects while keeping a good distance from them. 1:1 would require me to get too close and I wouldn't be able to handheld at that magnification anyway - I find even 1:2 challenging at 300mm. So the extra 50mm and the higher magnification make the 300 more interesting to me. Of course, if you need other focal lengths, the zoom is more convenient, but I am only interested in the long end. Ideally, I'd like to see a 300/2.8 or a 400/4 from Pentax.

Slightly beats Canon's famous 70-200mm f/4 IS not forgetting that the Pentax starts at 60mm and goes to 250mm
?
How did you come to this conclusion?
I'm still not that impressed w/ my 60-250/4 at f/4...and I am impressed w/ the Canon 70-200/4 images I've seen at f/4...

Yes, I know. Pentax used to have nice telephotos all the way up to 600mm. I hope they'll introduce again some models, but it doesn't look like I should hold my breath.

I don't quite understand their lineup strategy. Instead of the 50-135/2.8 and 60-250/4, I would have rather had a 70-200/2.8 and a 100-300/4. I don't understand why they issued two zooms that overlap in 60-135 range.

I think it's because they're trying to tailor to the APS-C format in that they're releasing lenses that with the crop factor equal out to those users would be used to from the film-era (16-50 = 24-70, 50-135 = 70-200, etc).

I have the 60-250mm and rarely use because the AF is so slow.
For a lens with a constant f4 aperture and decent range I find it much slower than my Sigma 70-200mm/100-300mm lenses which is a shame as I could pretty much dump the 2 Sigmas if it were quicker.

I took the 70-200mm and 60-250mm to a marathon last year and halfway through using the Pentax lens I swapped over as it was just useless.

The IQ of the lens is superb though and better that the Sigmas, especially good at people shots.

I agree with Mike. The 60-250mm is a superb lens that has fantastic IQ and is great for people shots. It is too bad that the AF is slow, as it's about the only thing not to like about the lens.

Here are a few people shots that I previously posted in the DA* thread.

there is also an important element that one must take not of the DA*60-250mm f/4 has and extending zoom system while the sigma 100-300mm f/4, It is all internal. The lens's physical size does not change with the zoom setting which makes the sigma less cumbersome to work with. The sigma 100-300mm f/4 also has an interchangeable tripod collar and it can be used with few other lenses that sigma makes.Though I love the way pentax implemented the tripod collar on the DA* telephoto lenses, I wish more makers made theirs that way.

carefully, 70-200/4 is a FF lens, however 60-250/4 is not exactly a FF lens.

Falconeye has said that the 60-250 is a full frame lens, as are the DA *200 and DA *300. As to what Pentax is thinking, their goal is to mimic focal lengths on APS-C that they had on film. So, for instance, they replaced the FA 85 with the DA *55. I think in this case, they had a goal of a 100-300 equivalent, but with a little extra, while the 50-135 is supposed to be a 70-200 equivalent.
