The best and worst of anything are ultimately matters of
taste and experience. As there is no accounting for
taste and experience is what life deals you we should
not argue about someone's nomination.

What is/are the worst lens/es you every took a picture with?
Leaving out the plastic-fantastics: Dianas, Empire Babies and
their cousins.

My picks:

o Cambridge 135mm f2.8 pre-set T-Mount. Uniformly fuzzy at all
f-stops, could only be focused to a 'least fuzzy'. I bought
it second hand, it was in like-new condition, now I am wary
of 'mint' lenses.

o Cambridge 400mm f6.3 {?} pre-set T-Mount. You would figure
after one Cambridge, who would buy another ...

o Schneider Xenar 150/5.6 of 70's vintage. This was, I am
sure, a bad example but I went nuts trying to figure out why
the pics were all bad, depth gauges - micrometers - pictures of
newspaper pages, until I remembered:

o Agfa Apotar/Solina, purchased with many months saving at age
nine. The lens wasn't bad, but the focusing helix
was frozen; new camera packed in orange tissue with a factory
seal and the famous green-gunk disease had already hit --
the focusing ring turned but nothing happened. After a year
of fuzzy pictures it hits - it's not my fault, it is the camera's.
After I fixed it I obsessively kept re-checking the focus and
adjusting the lens my microns until the screw threads stripped,
then it was epoxy time and leave the lens alone.
