I'm the owner of 58mm and 38mm DSO lenses (the basic lenses used in Richard's TRUMP lenses are Helios 44-2).
I've experienced a lot of itching because I enjoy something as close to this view as possible, but much wider - ideally about 20mm or so - that enters (or can be converted into) a PL or EF mount.
Do you have any recommendations? Thank you.
