Other Thoughts:The lens is OK. As for focusing it, things can be pretty tedious. I dont know why a better fine tuning knob is not part of the lens because this one has a course and fine tuning knob, but the fine one is too rigid to move small amounts and smoothly. It makes it hard to focus to the point where you know you are getting the best picture. And if you are using this with a megapixel security camera as I am, then getting the perfect picture is all that matters.
