Nikon Speedlight SB-20 brand_Stearman Press but the image is stillThe Nikon SB 20 is a reasonably compact, reasonably sophisticated flash for Nikon cameras. It provides TTL control with select film cameras, and for anything else, it operates in either Automatic or 5 step Manual modes. There's a cool rotary diffuser system and bounce setting that tilts the tube from 7 to 90 degrees from horizontal. A pretty neat flash in excellent condition.
