: I don't think you have done any damage. The lens elements seat onto a solid lip in the barrel and would be hard to get them "cocked", as to rotation of elements after cleaning that should not be a problem either as lens elements
are ground to exacting tolerances and are very symetrical. As to torque you can't compress glass and as mentioned the seating is very solid. I think you should be OK.

I recently cleaned the shutter blades on my
: QL-17 successfully but forgot to mark the
: position of the rear lens element when it was
: removed. I put it back in and tightened per
: my memory of the torque required to remove it
: but I'm sure I didn't get it back in exactly.
: Does it take just a small deviation from the
: factory setting to cause a focusing problem ?
: Thanks,
