Thank you for your comments Gentlemen.
This a7rii surely does make some of the best old glass really shine - these were taken with the Contax rf 1.5 50 lens, wide open, with the excellent Amedeo adapter plus the Novo M to E adapter. I don't like stacking adapters but this combo works fine .... no doubt due to the high precision machining of each of them.
I often think that I should give up manual focussing but this is one of the lenses/adapter combinations that reassures me and encourages me not to abandon such lovely old lenses yet.
