Nikon Speedlight SB-29SThe Nikon Speedlight SB 29S is a macro ringlight compatible with all Nikon cameras, though function will vary: it's TTL compatible with many film SLRs, and can be used manually on the rest. This flash consists of a camera mounted flash controller and a lens mounted strobe device designed to provide even, close up illumination for macro subjects. Includes adapters for lenses with 52mm and 72mm threads and original case.
