It is convertible of course, but how good it is converted I really don't know. In the early days all Dagors were sold as convertible lenses even though the single elements were not fully corrected. They were ok for portrait use but did not produce sharp landscapes. I once had an old 19" Dagor and use it in convertible mode. It had a lot of chromatic aberrations and was not really useful unless you use amn orange filter to block most of the red light.
