UV Imaging with IDAS UV372-80

Although I’m not sure which is the best target for UV imaging, I start testing with a small flower in front of my office. The time taken was 4 pm and almost overcast condition. So I don’t think it’s ideal for UV imaging. But El-Nikkor is well known as relatively high UV transmission lens. This lens allows me to shoot hand-held under such circumstances. Also I’m not sure this flower is the proper target or not. It’s there in front of me anyway.

My understanding so far is,  the dark portion shows UV absorption in this picture and it’s slightly different depending on a kind of flower, and  bees and butterflies etc are looking for honey from UV reflection. I guess it should be so hard for regular lenses to take UV hand-held in this condition.

Thanks for a mirror less camera, which allowed me to easily focus UV and IR through EVF. I will study more about UV and continue to take UV imaging. Then, I might be able to see something new and different.

Unlike other UV-pass filters available in the market, IDAS UV is well blocking NIR portion. Virtually no NIR leak allows for high contrast UV imaging.
