I've just acquired a second hand linhof 679 and on closer inspection the spirit levels on the two standards are slightly mismatched when clicked into the zero position.
I've tried to take measurements with a spirit level app - which has the same result as the integrated spirit levels.
It looks like the standards are 0.5 degree misaligned which doesn't sound much but I imagine could result in focus issues. I haven't got a lens or back at the moment so its hard to check. Is this a major issue?
Has anyone else had this problem? How trustworthy are the integrated levels? Would it be easy to fix?
