Nikon Speedlight SB-21 with AS-14 controller &nbsptype_Viewfinders 4E AF-S Nikkor lens isThe Nikon Speedlight SB 21 is a macro light for Nikon cameras (or others) with 52mm front lend threads. Can this work on other lens diameters? Yes, but it only comes with an adapter for 52mm lenses which, fortunately, includes most manual focus Nikon Micro Nikkor lenses. Nevertheless, it has full manual or TTL control (on compatible Nikon film cameras) and includes a diffuser panel. In excellent condition, with softcase.
