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

I've always been amazed that something as inexpensive as close up filters work as well as they do (other photography extras tend to cost, you know)and a "used" filter that you sold me to fit my new Nikon works as well and looks as new as the ones I bought years ago for my little Pentax. Whoever "used" it must have used it just once, it even had the original case it came in, in mint condition. Thanks.
