Most probably, the mirror is misaligned. Nothing that couldn't be cured
with a medium-sized sledgehammer.

Funny, though. A few months ago you were making one hell of a fuzz about
the minor shift in focus caused (or rather not) by the Noblex' focussing
mechanism and now you're using a camera with notorious film flatness
problems and whose mirror slap will practically guarantee blurred images
under all conceivable circumstances.

You're quite right, now I have thought about it. Even if the whole lens
were moving, the displacement between focussing near 15' and far 40'
would only be about 0.1mm.

I have never claimed to earn a living from photography. I work in
computers. Photography is my hobby and nothing more.
