Nikon SB-50DX

Check availablity: eBay.

This Nikon pre-CLS flash is for all intents and purposes a generic flash unit when used on a modern Nikon DSLR. Its legacy Nikon OTF TTL-mode and D-TTL is incompatible with CLS. Unless you have one of the legacy cameras it is compatible with, it is a manual flash without varipower settings (full power only).

The default slave mode is the legacy TTL SU-4 mode, which is incompatible with digital cameras. However, it can be set to fire in manual (full power only) when used as an optical slave (refer to p. 52 in the manual).

Comes with soft case SS-50 and infrared filter SW-9IR.
