Lens Calculator

This lens calculator can provide the viewfield dimensions for a given focal length and distance, or provide the focal length for a given viewfield width/height and distance.

The values generated by this calculator are for the user's reference only, and may not meet the user's actual requirements (picture clarity, etc.).
