What does "N", "DG", "ED" on lenses mean?
Like LTD, GTO, GT, GS, GTX, LS and all those letters they stick on cars to make them look fast?Henry Peach wrote: Some of those are listed in the "Photography Terms" post stickied at the top of this forum. Others can be found explained at the lens manufacturer's website. Some are abbreviations used by many brands, others are just used by a particular brand.
Shoot, learn and share. It will make you a better photographer.

N = Nano coating (reduces flare/ghosting)
DG = Sigma lenses designed for digital cameras (and can be used on fullframe/FX cameras or APS-C/Crop cameras) It's their version of a FX lens (or EF for Canon). They also make DC lenses which are only for APS-C cameras (similarly this type of lens is called "DX" with Nikon lenses and "EF-S" on Canon lenses).
ED = a type of glass that reduces CA (Chromatic Aberration)
