Quoting Scott Nelson [EMAIL PROTECTED]:
Pentax SMC FA 28-70 f/4. Has a small scratch on the front element (3mm

I have had this lens for quite a while, bought used, and love it. I use it
as mynormal lens. All of a sudden in the space of a few days it fogged up
on me. I don't know how or whether it is moisture, fungus or something
else. Any advice on whether it is salvageable and if so how expensive
I am new to the list and I also have the same problem with the same lens.
I have had mine on a ZX-5n body for almost four years with no trouble
whatsoever and then all of a sudden it becomes a soft focus model. I

For anyone who has seen it live or in photos, what is the styling? Is it
another black plastic type or a limited aluminum finish?
More like the style of the 20-35 FA. Molded hood, black plastic construction
and internal focus/aspherical element, by reports. I don't have the Russian
