The ML-2 is a three-channel infared remote for operating Nikon motor-driven cameras at distances up to 327' (100 m). This works with the F4s & F3 series when used with the MD-4 Motor Drive, the N70, or the FM2 & FM3A with the MD-12 Motor Drive. Other "10-pin" cameras like the F6, F5, F100, N90, N90s, D1 & D2 series cameras can also be used if combined with the MC-25 adapter cord. Features include automatic triggering, 3-sec delayed shutter release & either single shot or continuous shooting switchable from the remote position.
