I used it wide open with good results. It works great for me. But I sold it already to another members in PF. I am a blog writer and I change gear often to test all lens that I can afford to try out. The 70-300 is the best value zoom next to the DA 50-200. It is especially strong in 1:2 close up.
I sold my Tamron 17-50mm f/2.8 to prepare to get a 2nd system with a zoom in 16-85mm but that zoom has no competition to the Tamron. The beauty in Pentax system is that the SR in body make every lens in the 3rd party shine the best and 3rd party zoom lens can do as well as Pentax equivalent. It is a plain and simple playing field and it only gives more choices to customers. It is NOT the case with other systems. And you can check my reports on both lens in my blog pages.
After selling the Tamron zoom, I saw a used Sigma 17-70 f/2.8-4.5 and I grab it in an LBA urge. Yes, call me a LBA junkie. I bought good but seemingly less performant lens. But wait, I have my reasoning for all of my LBA purchases. While the Sigma 17-70 is not as fast as the Tamron 17-50, but it has the extra 50 to 70mm that I can count on and the result is less lens change. And it is cheaper. It is in the same vain as some people get Sigma 24-60 for cheaper price but I go for the 17-70 for its wide angle and the portrait need from 35 to 70. When it comes to lens purchase on zoom, it all boils down to one's needs. And in my view, there is no clear winner as it can differ on individual's need -- please excuse my LBA reasoning
Thanks,

thanks Hin for your insight
Yeah doubled up in 17/18-50mm range with tamron and sigma lens - will post on comparison photos later
Just curious if most folks' Tamron 70-300mm Macro lens are made in Japan or assembled in China like mine ?
