HOW MUCH DIOPTER DO YOU NEED?
Diopter values are based on the metric scale. A +1 diopter will result in 1 meter focus at your lens’ infinity focus setting. If you want to know the new infinity focus in feet, then you will need to convert from 1 meter to 3.3 feet. You’ll also want to work out your new minimum focus distance.
It is all a bit complicated, so we recommend you use the diopter calculator from our friends at CineSaga.
