About this item

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

Key Features

  • Diopters require no exposure compensation.
  • They may be 'stacked' for a greater macro effect. (+5 & +2 = +7)
