Latest Review Posted | SMC Pentax-DA* 50-135mm F2.8 ED [IF] SDM When it takes focuses, it frequently takes gorgeous shots and, in some lighting situations, it is the only lens I have that will take nice shots. However, that depends greatly on whether it will focus. People talk about sports shooting, as if that's the only type of action which can befuddle a camera. I tried to shoot a talent show tonight with stage lighting. If people weren't moving, it could be coerced into focusing and taking some nice enough shots. But, if anyone in the frame was moving at all, the AF would not work at all. I missed a lot of shots watching the lens hunt. I should have gone to manual much sooner, although, given the lighting, that wasn't easy either. It was very frustrating. In fact, by the end of the night, I was almost ready to throw over Pentax completely. Awful AF is really the only problem with the lens, but, unfortunately, it has the power to render its strengths useless. If you plan to buy this lens, plan on using manual focus a lot.
Update: the SDM motor never worked well and eventually died completely. I had a Forum member fix it by overriding the silent, non-focus system for just $30. At first, it worked fine. Using it to shoot a church service on Sunday, after less than an hour, the AF quick completely. It did come back later, but I expect much more.
Unless you always manually focus or don't mind a lot of frustration, find something else. |
