Looking for the ideal 55mm+ zoom

Hey all,
I'm looking for a higher focal length lens to complement my 18-55mm kit lens that came with my K-7. I've considered the DA 55-300, but I'm leaning more toward the Tamron 70-200 f/2.8 for the constant and lower f ratio which I feel will give me much better performance.

I'm shooting mostly outside, but once in a while, like last night, I might shoot a concert or something where I think the light gathering abilities of an f/2.8 lens might be a huge advantage.

That being said, I have a couple questions about the Tamron. The dpreview.com review said it had the following cons:
  • Slow and noisy autofocus motor
  • Somewhat clunky manual focus switchover mechanism
  • Tendency towards slight misfocusing (at least in Canon mount
However, it also said
QuoteQuote:
It's also fair to say that the body-driven Pentax and Sony versions may behave rather better all round.
So what I'm wondering is, will the Pentax lens on my K-7 also have these issues, or is the body-driven design a game-changer?



As a last word, I'm also up for looking at other lenses, these are the two that have my 'focus', though.

Peace and thanks,
MP

Not sure how obvious this is to you already, but I think you should check out the difference in size and weight between those lenses, and then ask yourself if you really want to carry a three-pound 70-200/2.8 around with you all the time just because you might occasionally use it at a concert. While some don't mind this, most people would probably be far happier with the 55-300 for general use, and then something else for low light use when necessary (the 70-200, or perhaps the DA*50-135, which I find to be a better focal length range for concerts - or even a 100mm prme).

The weight is something I had been considering. Now that you present it like that, I really do like that idea. The 55-300 would give me a great range for general shooting, and the 50-135 is probably much more of the range I want for low light photography.

I think I had the pieces there... but thanks for putting them together for me. Best plan I've heard.
