For what ever it's worth:

One of the best pieces of general photo advice posted on the LUG in the 9
months or so that I've been here came from Ted Grant - of course - and
regarded focusing:

Keep your lens focused at or near infinity, and then when you home in on a
subject, focus in closer. I'm not quite sure why this helps, but it really
does speed up the focusing process and greatly reduce see-sawing.

I don't have a Noctilux or the 75, but I do have a 35 Summilux and the 90
Summicron, and find that out-of-focus images has really ceased to be a
problem. Well, pretty much ceased to be a problem... ;-)

I'm not sure it makes a difference, but I thought this was discussed some
months ago.  Like Mikiro, I have trouble getting sharp images at f1.4,
mainly  when using the subject's  "forward eye" as the focus point.
