A rewind to film-based UV photography. The F4 loaded with Fuji RTP film combined with the UV-Nikkor 105 mm f/4.5 lens, Nikon FF filter in a hinged AF-1 mount, and the SB-140 flash formed the base foundation for my UV photography during the early '90s.
Decades later, I still use the same UV-Nikkor lens and SB-140 flash, so these were made to standards almost unheard of today. Food for thought, perhaps.
