Originally posted by normhead I personally can't imagine shooting action with a manual focus lens,
I shoot skateboarding by prefocusing. Even when using auto focus lenses. What is the point of auto focus if you have composed and know where you want the subject to be when you take the photo? This obviously doesn't work for all action photography

Welcome, from Cincinnati, OH. And all of the Pentax Forum! My main setup is the K30 an 50mm1.7, it is such a great lens if you find a good copy! For product shots I would recommend a normal prime (35 or so) because you will get a good enough dof without too much perspective distortion you'd get from a wide angle
