Hello fellow Pentaxians!
I am trying to learn how to deal with front focusing and back focusing that I seem to encounter quite often with the K-5 and a variety of lenses that I've used so far. I'm not sure if inaccurate AF is a result of the camera, the lens, or both. So here are a few questions from someone that doesn't know much about cameras:
(1) does front focusing mean that the camera is focusing closer in distance to the camera than the intended subject? And alternatively, back focusing means that the camera is focusing further away than the intended subject?
(2) if I am having front focusing problems (and assuming the suggested definition for front focusing noted above), will I be applying " - " or " + " to the micro adjustments in the K-5?
(3) In the K-5, the range of micro adjustment is -10 to +10. Does anyone know the equivalent in real world measurement the amount represented by each micro adjustment unit? I.E., does applying 1 micro adjustment unit equals to 1 centimeter ?
(4) What is the best way to test whether the camera/lens is auto focusing accurately?
Thanks for the help everyone!
