Hi Reso,
I have both the Sigma HSM & the Pentax, they are two very different creatures, The 70-200 is very fast focussing, but no where near as sharp as the Pentax which is fairly pedestrian by comparison....

I you can Keep the Pentax, you wont find a sharper get a Sigma HSM as well....
& yes I do suffer from LBA, but it is nice to have both in the bag....

A few bits & Bobs

Hi Phill,
I've had both the Pentax 50-135 and a Sigma 70-200mm F2.8 EX DG OS HSM. The Pentax is a lovely sharp lens but can be pretty slow to auto focus. The Sigma was fast and much more suited to auto sports, especially when turning off the Pentax SR and setting the in lens stabilisation to panning mode. I found my copy of the Sigma pretty sharp and not much behind the 50-135.
