wickedly slow, really? I rented one for a week and shot low light concert work and I was not only impressed with the very obvious fast speed of the SDM, but almost didn't want to give it up and go back to my screw drive lenses, lol. I did not have both at the same time but my recollection was that it was most definitely faster to focus than the Tammy. Hopefully there is somebody who has both who will be able to compare these.
I will also say that of the hundreds of images i shot with the DA*50-135 and the DA*200, the IQ of all looked great, but not photo looked significantly better than the pics i am getting out of the Tammy. Obviously I had no side by side comparison, but as far as IQ is concerned, the Tammy is not leaving me wishing I had bought the Pentax.
