  • The C8 is bigger than the one I remember being tested. Unfortunately, the Ultravioletphotographydotcom website is down while it moves to a new host, so I can't check. Interested to see your test ...
  • Yeah, an electronics/scientific light designer tested the Nemo and found it put out less than 15 watts. It was about 7 watts. Your Convoy sounds larger than the one I remember being tested. That ...
  • Ultravioletphotographydotcom compared one of the Convoy to the torch they nick named Nemo. Nemo is fair amount brighter. It is also quite a bit larger. The front screw in filter is at least 40.5 mm. ...
  • Thanks for the info. Modifying a flash for UV is on my to do list. The "Nemo" came from here: https://www.ebay.com/itm/233620900023?var=533325661007. It is probably also on Amazon. I purchased the ...
  • That is a wild battery! Construction is top notch. No wonder it is taking time to complete. Looking forward to seeing your images. Tried UVIVF for the first time. Used the 15w 365nm "Nemo" torch. ...
  • My UV project was derailed by K-01 failure. Parts aren't available for repair.  Bummer. Wanted to avoid missing the end of the season. Couldn't find a used Full Spectrum camera. Buying a new ...
  • Thanks for the info. Goggles look good and will fit over my stock glasses. Florescence is something I want to try. If only work didn't get in the way :). Thanks,
  • Still need to get UV protection goggles and some type of light source for indoor use. Need to research the goggles. They will have to work over my glasses. The Kyoei Acall 35mm F3.5 clone arrived ...
  • Cool images. Interesting to see the comparison between formats, with the unconverted vs converted twist thrown in. Guess the winner could depend on the subject. Trees & water favor a converted ...
  • Doesn't sound too difficult. The Metz should have more power. Will check out their pricing. Thanks,
  • Thanks for the link to the presentation. It clarifies many points and adds lots of details. I totally missed it. It would turn your K-01 into an 850nm camera. Not a bad thing. I doubt the light ...
  • Good question. Even if it is just fancy filters on a stock flash, it is simpler than trying to get filters to fit a flash perfectly. Plus being able to quickly change from UV to IR is a big ...
  • Was looking at the IR Chrome filter on their site and saw the flash. I have a K-01 full spectrum. I know people are modifying flash units for UV/IR, but this is ready off the shelf and does both ...
  • Bought a yellow one during the fire sale. Still use it once in a while. The brick shape packs well. Thought the K-1 and 645Z would slow my APS-c use to a crawl. Then, a few weeks ago, a great deal ...
  • The flash you're building sounds incredible. The Metz UV output is fairly low. Why use it vs one of the brighter UV flashlights? How are you going to protect yourself from the monster flash? Are ...
  • Great info. Also want to try UVIVF. The modified flash is intriguing. Have a Sunpak 555 handle mount that isn't being used. Don't know much about UV LEDs. Is it portable or studio? Unfortunately ...
  • Excellent images. Especially like the cars. Thanks for the links. Hadn't heard of your 28mm. It is difficult to find wide-angle UV lenses. Thanks again,
  • Created discussion thread Anyone doing UV photography?
    Just purchased a full spectrum Pentax K-01. I've done film & digital IR, but UV seems more difficult. Most lenses are poor at UV. I lucked into a Spiratone Kyoei Acall clone. I already owned metal ...
  • It is possible cultural differences are involved. They are using a 2nd language to describe the products. Often times excellent +++ mint, etc. are used to describe the lens body's condition. They ...
  • Ouch. Perhaps it can be cleaned before the damage becomes permanent? barondla
