Greetings Marc, You asked what the red point within the DOF scale might be on your recently acquired lens. That's the focusing adjustment point for infrared film. Since IR doesn't focus on the same plane as sunlight, you have to adjust your focus accordingly. When shooting with IR film, focus normally, then note where the normal focal point on the lens is located & move it over to the red point. You are now focused for IR. If you haven't ever shot IR before, give it a try. It's VERY interesting. Best regards, John _______________________________ John R.
