As pengland wrote, everyone here is trying to help me, and I greatly appreciate it. This is a very difficult subject to discuss. We\'re all on the same team here, and we\'re all still learning things as we go.

Paul, yes the front lens assembly can be removed after unscrewing two of the three retaining rings, but it has to be the correct two.
-----------------------
Jim, regarding the three side screws that hold the front \"hood-like\" piece: THERE MAY BE DIFFERENCES IN VARIOUS VERSIONS:
On the two 58/1.2\'s I\'ve opened so far, which are both early ones (ser 250xxx) you cannot get to those screws until the front assembly is removed. Additionally, I completely disassembled these two lenses, without ever removing the name rings. I can even see the infinity-stop screws.
I have a feeling that these versions are mechanically different from the later ones, which may account for more than a little of the confusion here. (I see a related question on your infinity-adjust routine, but will address that later, when I\'m sure)
I have four of the later ones as well. As soon as I have a chance, I will open one of those, and see if indeed there are differences, and report here.
-And thanks for your offer of phone help. I may indeed call you this weekend to discuss.

So, no more bunched panties, fellas.
Again my thanks to you all.
