Yes, a tripod will solve entirely the problem. I am going to look around for a suitable one. Could you recommend a suitable good ballhead? ... but an amateur has to be mobile, too.
I agree that the main source of difficulty is "unusual" behaviour of the image in the WF. It is something that needs a good deal of skill and practice. Using such a type of WF is now "forgotten knowledge". I remember years ago many people (my father too), more or less succsessfuly, used TLR cameras with the same type of WF. .... practice, practice, and even more practice... A former leader of a power said: "Learn, learn, learn"!
As to the longer focal lens, I currently use 90 mm lens sometimes at 1/30s on Leica, and 18 x 27 cm pictures are sharp. This size surely is not a "philately".
Thanks again for your attention to my case.
