Thanks all for your responses! Not all points are clear yet but now I have information to make the choice.

@pearsaab eagerly awaiting for your tests with binoculars and with K-5 IIs concerning AF speed.
i have a 8x42 pair of binoculars which are comparble to about 450-500mm lens...hope that helps and will let you know on the k5iis...thanks, amy

Thanks! That helps, though a bit dissapointing for me since I used to that 8x binoculars and was hoping to get something closer to them. Looks like what I want is DA* 300 and maybe some teleconverter.

if you go for the da 300 and the 1.7 pentax adapter they work very well together but the adapter is not WR so you will be in essence using a not WR lens so that may add a little bit of a dilemma

Hi I have the DA300 and it is sharp(after adjusted at Pentax service..) & also the AF 1.7..if in rain use a lens bag over it,no big problem.You have to prefocus 1st then the adapter AF works oK,maybe the new one from Pentax this year??? will be better

Taking all the above into consideration the questions are:
1) Can you say if, e.g. DA* 200 at F/4 is so much sharper than 60-250 at the same aperture at 250mm that it provides more details?
3) Which of the lenses focuses faster on K-5? Is AF speed of any of the lens is better on K-5 II(s) than on K-5?
5) Which lens, 300 or 60-250 appears darker in viewfinder (or maybe T-value is known somewhere)?
6) Is lens creep an issue on 60-250?
7) How easy it is to hand-hold DA* 300 to get decent sharpness?
8) Having in mind that Pentax one day will release DA* teleconverter, wouldn't it be more practical to have it along with DA* 200 in the bag than to carry DA* 300?
1) Yes it is.
3) I would say that the 200 is the slowest, and 300 the fastest. The main advantage for the K-5 II(s) is the centre AF point that is good for f2.8 and only the 200mm lens takes advantage out off this.
5) I think they are about the same, but if one wins that would be the 300.
6) No.
7) I can't, but other people can.
8) Depending on how long of a lensyou want. The 200 will become 280mm/f4 and the 300 a 420/f5.6

Apropos magnification compared to binoculars:
The K20 spec lists x0.95 viewfinder magnification with a 50mm lens. That fits, because with a 50mm lens, the size of an object with one eye through the viewfinder and the other eye open, is almost the same. So, a 400mm lens would provide around 8x magnification when viewing through the camera (actually 7.6x = 400 / 50 x 0.95), when compared to binoculars or a telescope. This is also the commonly claimed magnification for telephoto lenses when used on 35mm where 50mm was typically viewed as the standard lens. Whether you wish to further include a crop factor for APS-C, is really a question of how much you are prepared to enlarge your taken image.

Well, I've just taken the plunge with a 60-250. It's Ron's fault! It should be here in a couple of days. I couldn't decide between a Tamron 70-200 2.8 and the 60-250 4.0. A little more reach and weather sealing won out over speed - hopefully that was a good decision. I'll be using it shooting sports like cycling and skiing which is often in less than ideal conditions an often with plenty of light. But shooting indoor stuff like dance may be harder than with a faster lens. I've shot some dance with the DA L 55-300 and IQ was ok but it was slow and the variable aperture made shooting manual while changing FLs pretty tough so constant aperture will be nice for sure. I'll probably also some general use too like long landscapes and wildlife. If it was 2.8 it would have been a no-brainer but I still wonder if it was the right choice. I figure if I decide it wasn't I can probably get about what I paid (used) and get a 70-200 2.8 instead.

Good for you Matt! In your capable hands it will be a stunning lens. It is my favorite/most used lens - even with my feeble attempts it even makes my images look good sometimes!

Well that certainly doesn't look feeble. Makes me wish it was here now!

In my opinion, I would take the 60-250.
If your hiking, you never know what you will encounter, and a zoom is so much more flexible. I had a DA*300mm, and while it was fantastic, I would find it limiting. If Pentax made a WR prime in the 21-28mm range, all you would need are those 2 lenses for anything you may run accross on the trail.

Could someone give me a link where it is explained why K-5II center AF point works better for f2.8 lens? That's the only thing that I need to know before making final decision.

And thanks everyone for your input. I wish I could afford all three of them

@stormtech absolutely fantastic shot! I guess it was taken with 60-250. What aperture and focal length did you use?

Thank you! I am quite proud of the batch of shots from that day. The photo above was @250mm, ISO 200, f5.6, 1/200 sec (DA* 60-250) with the K-5 (I now have a K-5IIs). It was actually taken through a double pane sliding glass door. We had these uncommon visitors last winter - the Common Redpoll and Pine Siskin - all the images of these guys were done with my first experiment with catch-in-focus.

Common Redpoll

Pine Siskin

American Goldfinch

I may need to revisit these shots and brighten them up a bit, but they reflect how I saw them that day being heavily overcast and snowing.

Not found any descent now, maybe someone else:

nice shots there ST..what is 'catch in focus'? have I missed something.... how far away were you? 200 sec is slow..tripod used? that's a heavy lens...
