The Heliopan Close Up 1 Filter is a convex diopter designed to decrease the minimum focus distance of any lens in order to produce a shorter working distance for close-up photography. No exposure correction is required. For best results stop down to f 5.6 or f8.
- Convex lens design and +1 dioptric strength lessens the minimum focusing distance of any lens for close-up shooting.
- Single coatings on both the front and rear offer protection to the glass and help to improve light transmission and image quality.
- Constructed from Schott glass for optical clarity.
- Brass filter ring helps to prevent jamming and provides additional strength.
