Novoflex 400mm f/5.6 and 600mm f/8.0 for UV-photography

[ulf]

Thank you Dunk, for the added information about those lenses.

I have updated the information in my technical lens data topics here:

https://www.ultravio...lenses-unusual/

 

If you find more to correct beside the source for the optics, please let me know.

 

It is interesting to know that there still are people at Novoflex knowing about the history of the older lenses, that are not sold anymore.

Is it still possible to contact Martin Grahl?

 

The Telyt 560/6.8 is not suitable for UV-work.

I have one of those and the measured UV-transmission is not that good.
