In my experience, many of the early (dark grey plastic) FA lenses had
what I called a floating front group of elements, and they DID wiggle
around when touched. It should not affect AF, or manual focus, for
that matter, as focus is focus. However, I also found that when using
a polarizing filter, you had to adjust the filter first, then focus.
From a mechanical point of view, I would surmise (might be wrong)
that the moment of movement of that front element/group would be
designed to wiggle around the circumference of the optical (or
physical) curve of the element/group, so that focus did not change.
Pretty far out, huh?
Nothing wrong with your lens... It's an Asahi special design
feature! :-)
Nothing wrong ... other than it annoys the bejezus out of me. The wiggle
does not please me at all.
