I have to agree. All this business about sample variation is 90% BS. It happens sometimes but relatively almost never.

I have 3 copies of this FL 58/1.2 and while the exterior conditions vary the images they produce are absolutely identical.

Well in the earlier days (say, before about 1972), there was some variation due to factors beyond the control of the manufacturers. Variations in glass from batch to batch was a problem. Production methods were more primitive compared to today.
Some of this is discussed here:

So is Canon still in the '70s with the lens production? - http://www.slrgear.com/articles/variation_canon50f14/canon50f14.htm
There are also numerous reports on Sony alpha Russian forums, people choosing from 5 "bad" copies a "least-bad" one... I'd provide links, though I doubt many people here speak or understand Russian. "Sample variation" is still a subject to be considered.

Well I'm not surprised at all. This is one of the problems with auto-focussing systems. It's one of the reasons I stay with my manual focus Leica equipment. |

Before you will decide to get it make sure that filter thread is in perfect condition as to service aperture you need to get to this lens from both sides (front and rear). Construction of the aperture is however bullet proof except maybe springs.
BTW. What is asking price? |
