Full Version: Minus 1inch ?
When focalCal gives you a LCD to Projection Lens distance, do you automaticaly Take 1 inch off that number to allow for focusing ? 1inch in and 1inch out ?
It depends on what your focus mechanism is. If you are using a shower drain then yes you do need to subtract a little bit because you can't screw the lens in past the ring. I hope that makes sense. Basically just make sure that you can move the lens backwards and forwards for focus.
