E: Electronic Diaphragm

The new electronic diaphragm "E" lenses only work on Nikons introduced since about 2007. They work perfectly on all FX cameras.

They work only on the D5, D4, D4s, D3, D3s, D3P, D3x, Df, D810, D800/e, D750, D700, D610, D600, D500, D300, D300s, D7000, D7100, D7200, D5500, D5300, D5200, D5100, D5000, D3400, D3300, D3200, D3100, Nikon 1 J1, J2, J3, J4 with FT-1, Nikon 1 V1, V2, V3 with FT-1, and Nikon 1 S1, S2 with FT-1.

These new "E" diaphragm lenses will not work on the D1 or D2 series, D100, D200, D90, D80, D70 series, D60, D50, D40 series, or D3000, and will not work on any 35mm camera. The diaphragm will stay open at f/2.8, which may or may not be a problem for you. In the case of tele lenses like the 200-500mm f/5.6E, this isn't much of a problem because we usually shoot long lenses wide-open, in which case the E lenses are compatible with everything.
