Thanks everyone .
I have a IIIc Elmar and 1933 Black/nickel II Elmar one of which I may , at the moment , sacrifice for a 16-50 for the X-Pro1 .
I have a Summitar which I love with the M8 plus that adapter for Contax lenses - including that 1959 J3 in genuine Contax mount which Brian Sweeney had left over from his other conversions .
I accept that the X-Pro 2 is excellent , bayernfan , but the M8 was a glitch in inexpensive DSLRs .
Being retired , I could not justify £1300 for a camera body when my NEW X-Pro 1 was less than £300 .
It's this wholly , unexpected bargain basement camera with a great 27mm f2.8 which has created this situation !!!
I was thinking of a cheaper Fuji complete with the 16-50 as a second body for mono ... but there is no hardship to take out the X-Pro with 16-80 and 27 PLUS the M8 with CV 35 f2.5 Color Scopar / Summitar.
The X-pro seems to have broken the DSLR [ Sony A35 / 35mm ] habit !
