In my setup It is almost one stop slower that a EL-Nikkor 80mm old metal type and Baader U filter.

It still produces nice UV-images and is a very nice super-sharp lens for VIS

 

I tried two in hope of that the second one I got, a year older would have a better UV-transmission than the first.

When I tried the second one on the camera, not only measuring the transmission as I did with the first, I could mot part with the lens, due to the nice image rendering.

 

You have to use it on a helicoid or bellows for focussing.

Mine is deeply mounted in a M52 to M42 36-90mm helicoid, with a short M42 extension tube, to both reach infinity and get a good close-up magnification.

The front filter thread is 49mm
