  Nikon Speedlight SB-25

In appearances and power ratings, the SB-25 looks a lot like the SB-24. However, it adds a number of useful features, including the pull-out diffuser for 20mm lenses, a locking pin on the hot shoe, red-eye reduction, and the FP high-speed sync flash mode. Introduced in 1992.
