How many versions are there of the Canon FL 58/1.2?

This site indicates 2 versions but with little further info.

Some lenses from that era were actually marked as version "II". Does anyone have pics of an FL 58/1.2 marked as such or any info about the differences between the versions.

TIA

i have one but it has no markings either I or II.
all i can say is it is one heavy lens on my camera body!

I loaded both URLs and centered them to the same spot, then clicked back and forth between them. The only thing that changes is the title of the lens and the year that it was made. Everything else, including the photo, is the same.

So I'm figuring it was a minor difference, and probably not one you'd notice.

Some months ago I sold a Canon EF 28-80mm lens because I had two. One was a II and one was a III. I could not for the life of me find any difference at all between the two lenses, just holding them in my hands and looking at them. But the III was sharper than the II so I sold the II. I don't know, though -- this sharpness difference may have just been the difference between two lenses and not necessarily two series. So all I'm saying is don't assume that a II is gonna necessarily be better than a I.

Apart from the date of release, seems to be very little difference between the two. Maybe it IS purely a date/serial number thing?

Unfortunately, I have the 55mm f1.2, so can't help with markings.
