The Kuribayashi 35mm reaches much deeper into UV, even a bit below 320nm and shows a rather high UV at 365nm transmission of over 80%. However the similar looking W. Acall 35mm seems to be a very different beast, as it has at 365nm only approx 5% UV transmission, so basically none useful at all!
I have written about that lens before HERE
Stay tuned, more will follow on that fascinating subject...
