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

after i have been using for a while........the only thing i don't like it's not easy to focus and it takes time......to get clear focus...... but it's worth to have it since it's cheap enough to own if macro lens is just cost too much and it's fun to try something differently rather than just changing a nice lens to get a close-up image shot..........
