B + W 62mm +3 Close Up Glass Filter - NL3
Diopters are optical close up lenses that make macro photography easy. When added to a lens they greatly narrow the depth of field while reducing the minimum focusing distance of your lens. The effective focal length of the dioptere are: +1 = 1000mm +2 = 500mm +3 = 333mm +4 = 250mm +5 = 200mm
- Diopters require no exposure compensation.
- They may be 'stacked' for a greater macro effect. (+5 & +2 = +7)
