Nikon SU-4

Description

The Nikon SU-4 is a handy little TTL flash accessory that clips into any Nikon TTL flash and accepts communication from any SU-4 compatible Commander flash. Can also be used in non-TTL remote mode. Doesn’t need batteries, takes up almost no room, does something real helpful, and they’re not making them any more… perfect. But hey, here’s one now!
