I use this combo Tamron 70-200/2,8 and K1 and I am very happy with it. I could say that it's focusing better in low light than Pentax 24-70/2,8! While with 24-70 I had problems of getting fast focus and having lost some good photos, I cannot say same thing for Tamron 70-200/2,8

Good quality, very sharp at 2,8, superb color rendition, beautiful bookeh, not so heavy for this zoom, in conclusion, a very good choice.

Here is a shot I took earlier today. Whenever I do shots like this I use manual focus. This lens is very good on the K1.

Reading most of these comments, you'd get the impression people were only using the lens to shoot in church, or at the local library! Yes it is a screwdrive lens, and yes it does create slightly more noise than some modern focus motors. I've only ever used screwdrive, SDM and HSM focussing systems, and I will take the speed and noise of the screwdrive over the quieter, yet s-l-o-w-e-r, speed of the others ANY time!

I have used the Tamron for the last three years to photograph my daughter and her soccer clubs, as she progressed from competitive league soccer, up to her current high school club. It is plenty fast enough to focus during these games, and as I have gotten better at photographing the game over the years, it has never let me down.

One more thing. I got my first Pentax DSLR (K7) in 2009, and have been very happily using a K5IIs for the last two years. I have also improved my lens collection in that time. I own most of the DA Limited primes; the FA31 & 77; the Tamron 17-50 2.8 and the Bigma (Sigma 50-500). I can honestly say, with no hesitation, that it was the IQ of the Tamron 70-200 2.8 that truly blew me away the first time I used it. And it continues to this day. I am not saying that it is the BEST lens I own, only that its' performance really surprised me, considering its' relatively modest price.

(Sorry no pics. Don't currently have access to them.)

Although I haven't moved up from my K5, yet, I also have the Tamron and don't find the focus noise to be too noisy. Neither do my chosen subjects.

Yes it is a screwmount lens
Err. No. That it sure ain't. Screwmount would be M42.

Screwdrive AF has several disadvantages, the noise being but one. Another one is speed.

What leads you to the belief that screwdrive AF is faster than HSM/SDM? The only HSM lens you mention is the "bigma", so you're comparing pears and apples.

Try to get your hands on either the Pentax 70-200/2.8 or one of the Sigma 70-200/2.8 lenses (either with or without OS), and compare them with your Tamron.
I'm not saying that that's a bad lens, but ...

This is very good to know. The main reason I want a fast 70-200mm is for photographing my kids running around. A few months back we were out in the woods with some friends and their kids - they were shooting with a Canon DSLR fitted with the Canon 70-200mm whilst I was using by K-5 with the 18-55mm WR kit lens. Now that's not a bad lens, but in the often relatively gloomy lighting of thick woodland it does not do well against rapidly moving and relatively distant targets and as a result the photos our friends got were much better! Hence, a 70-200mm f2.8 became one of my must have lenses (right after a macro which I have now ticked off with a Tamron SP 90mm f2.8).

Hmm... my D FA 28-105 DC obliterates any screw drive lens I've tried. It's not only raw speed, but also it doesn't do the micro-corrections typical of the imprecise screw drive gears.
Pentax abandoned the micromotor SDM in 2008 (when they launched the last such lens). Since then, it's DC and now they have faster versions.
