I spent months making the same decision and eventually settled on the 50-135 DA.
In the end it just ticked more boxes for me, the weatherproofing being the most important one.

I certainly haven't regretted the decision, even after getting one faulty lens.

Is the lack of tripod collar on the 50-135 a major issue?

The lens is a lot smaller than you are going to think it is.

Not in the least! The lens is small enough that it does not need a tripod collar and if you ever shoot a wedding or other such event, where you are shooting hand held and all day, you will really appreciate the size and weight of the 50-135 over a 70-200 designed for the larger 24X36 format. The later is appreciably larger and heavier.

From the comparison pics i sent you last night you can see the differnce and feel in weight. I love the 50-135mm hand held. Its perfect. Doesn't feel weighty or big. But since your getting a little more zoom i guess the size and weight was needed?

People bring up the great point about the weather sealing. We had some severe flooding here on post a month or so ago and i was out in the rain with the K20D and 50-135 and it did great. Don't think i would have done it with the 70-200mm. You definitly dont need tripod for the 50-135 and after using the 70-200mm a little you don't "need it" but i can see where having one would probably make a bigger difference than if you did with the 50-135. I might be heading back to the seoul grand park zoo this weekend, where i really want to utilize the 70-200mm but i want to pick up a tripod to see how much difference it will make. This is why i got rid of the sigma 100-300 just too big imho for handheld.

I have the Sigma 70-200 HSM and have used the 50-135. The only reason I would pick the Sigma is to get HSM. Is much faster than the 50-135. If IQ is what you want, and don't need the extra length go Pentax. The Sigma is no slouch stopped down but the 50-135 is still better IMHO. If weight is an issue the Pentax is extremely light, lighter than my Tamron 28-75 f2.8!

I agonized over the same decision for months. But now that I got the DA* 50-135, I don't know how I could have thought otherwise. The DA* 50-135 is not that much bigger than many consumer telephoto zooms (e.g. the 18-250mm). It doesn't need a tripod collar and its great handheld. Its a really good example of Pentax using the APS-C format to make more compact glass.

So it doesn't have the reach of 70-200 zooms, but what I have done is that I have paired it with the Sigma 100-300mm and skipped the 70-200 range altogether. I basically figure that I'll always need the 50-135 range in the camera bag. But I will not always need the 135-300mm range. I kind of find the 70-200 as stuck in no-man's land. A bit too long on the short end and a bit too short on the long end. The other great thing about the Sigma 100-300mm is that it is amazingly sharp through the whole range and definitely comparable to the DA* 200mm and 300mm.

You add weather sealing to the mix, and definitely I'd say skip the 70-200mm tamron/sigma. Get the 50-135mm and couple it with the 100-300mm. Well that is my experience.....
So I'd say skip the 7

I tell ya i am in the same boat. I currently have the 18 to 50 EX DC 'macro' from sigma and it has been a great starter lens to me. I think this along with the 70 to 200 F2.8 along with I need the next step up and the 50 to 135 seemed logical however a friend who recently got it told me the lens is very soft at 135 even at F4 ... which i am wondering if its just his copy or a larger problem.

I its fair to say this along with my current sigma and the 100-300 F4 round out the top three zooms sigma makes with the K mount sooo its all pretty tough decision.
I ran a test between my DA50-135 at 135mm F2.8 and my A 135mm f2.8 prime when i first got it. The test pictures were done of a white picket fence and the camera was on a tripod with several repetitions. SR off and 2 sec timer on. At a 100% crop, i couldn't tell the difference in sharpness between the two lenses. At 200% crop, the prime was sharper. Unless i want a lighter weight lens to carry around, i do all my shooting with the 50-135 for that range instead of the 50 and 135 primes that i put on before.

I have also used the lens for photographing head shots and advertising shots for a local playhouse production. A photography friend who was shooting with me, was trying out his new Canon 70-200mm lens, and i noticed half way through the play, that he replaced it with his old 17-85mm zoom, because the 70mm was not wide enough.

I think that for around town, small events and even portraits, the 50-135 is a perfect range for my needs.
