Purest Unobtainium!!  UV Lens and Filter, Exacta Mount!!!

Purest Unobtainium!! UV Lens and Filter, Exacta Mount!!!

Found and bought on Internet, a 50mm f/3.5 macro uncoated pure quartz lens, a U340 filter (passes 300-380nm, blocks visible light) T-mount, with Exacta, SA, and C-mounts, screw lens covers, all mint. Unobtainium, finest kind! Costs too much, but if I can make this work, there will be photos in ultraviolet light. Will fit my Topcon and Sigma SLR's.

    @hervinsyah Only thing, they most dramatic thing I can do with this is shoot flowers for UV florescent landing instructions for bees. Bees see in UV. I live in a semi desert (near Los Angeles), and presently flowers are out of season, but I am trying.
