Selfmade Quartz Singlet Lens
Klaus,
This is a wonderful capture! The picture is alive. The glow is so effective. Tell us about the focal length, film or digital and the source of this magic lens!!

Thanks Asher! Well, it was taken with a selfmade contraption (focusing helicoid mount with taped in lens, no aperture) consisting of an uncoated quartz singlet lens. It was shot at full aperture (geometrically f1.0 actually) on a digital SLR camera. That lens element I found long time ago in a optical surplus store when I was searching for UV capable lenses. That idea was influenced a bit by the design of the Struss Pictorial Lens and the Hanovia Kalosat quartz lens, both hard to locate today. I am used to build such solutions with the help of my mechanic and as this turned out to deliver good results, will be turned into a mechanically well made solution (tape is just for testing, not for later use...)
