Spec sheet

An electromagnetic diaphragm system, which is

a standard feature for Canon-mount lenses, is

now utilized in Nikon-mount lenses*. More

precise diaphragm and aperture control is

possible because the diaphragm blades are

driven and controlled by a motor through

electronic pulse signals.

*Available only with cameras compatible with the electromagnetic diaphragm (D3100, D3200, D3300, D3400, D5000, D5100, D5200,

D5300, D5500, D5600, D7000, D7100, D7200, D300, D300s, D600, D610, D700, D750, D800, D800E, D810, D810A, D3x, D4, D4s, Df,
