Quartz Soft Focus Lens does Butterfly / Bee Vision

A quick test today confirmed, that my f1.0 Quartz Soft Focus Lens is able to reproduce also ultraviolet. This was proven using my XBV2 butterfly / bee vision filter, which allows to map in UV (ultraviolet) into the visible range as blue, leaving the green and red channel intact.

So you see, that the famous Rudbeckia UV "bullseye" pattern is correctly being reproduced and also the strong UV reflection from the central pitch black center (for us - hence the common name "Blackeyed Susan")  most prominently visible at the leftmost flower.

Stay tuned, more will follow on that fascinating subject...
