I've recently gotten a UV sterilizing wand such as shown here: UV-C Sterilization Wand Review & How to Kill Germs - YouTube
It emits UV-C which is a germicidal part of the EM spectrum. It kills microbes, bacteria, fungus, viruses, supposedly by breaking apart their DNA. I've tried it on dirty wash-cloths and sweaty badminton shoes and it does reduce/remove the odours, so I believe it is killing microbes.
I radiated with UV-C, a lens of mine that had some fungus, and wiped the fungus away with a wet tissue, and shone some more. The fungus has not grown back, although the glass is not completely unscarred by the experience.
And I also want to share that I feel that after radiating my other lenses and the camera CCD with it, the photos have gotten back that nice sharp je ne sais quoi quality to them. My theory is that fungus/bacteria/microbes on the lenses, on the CCD and on the electrical contacts cause poorer autofocus and softness/deterioration to the photo quality. This is obvious when there is fungus growing on your glass, but even in less severe cases, I think it's probably still true.
I just want to know whether anyone else has experience with these UV sterilizers on their photographic equipment and whether they experience similar benefits?
I wonder if there's a market for this product in photography. Dry cabinets prevent or retard fungus growth, but doesn't kill the fungus. UV-C apparantly does.
