What do all numbers and letters in a lens name stand for?
I'm a newbie to DSLR photography so please explain all the numbers and letters in a lens name… For example Nikkor AF-S DX 10-24mm f/3.5-4.5G ED.
AF-S - means the lens has an autofocus servo motor
DX means it's specifically meant for crop sensor cameras.
10-24mm is th focal length range (it's a zoom lens).
f/3.5-4.5 means the maximum aperture you can get in the zoom range (f3.5 at 10mm and f4.5 at 24mm).
G means the lens has no aperture ring - the aperture is controlled by the camera body.
ED - relates to the dispersion coating on the lens which helps prevent flaring.
