Today about another, faster filter for reflected UV photography, as there still seems to be some demand for handheld UV shooting or shooting at higher speeds for instance for video work. This here is the XNUV2, that I finally tested for the first time now using the Baader-U UV pass filter for comparison, a UV-Nikkor 105mm quartz flourite lens and my UV sensitive camera. Light was late evening light on a rather dull day.

What is important to notice is, that also the XNUV2 is also able to precisely reproduce this distinct flower UV pattern, as well as it shows good sharpness, as compared to the Baader-U filter. And most importantly it is 2.3 stops faster than using the Baader-U filter, which is quite an impressive result as it will make it much easier for video work.
I will report more about that filter here later, as more testing needs to be done.
I have written before about a faster XNUV filter HERE
Stay tuned, more will follow on that fascinating subject...
