Just to cover all bases, is the focus ring pushed forward exposing "Auto Focus" right above the distance scale window, and are you sure that the aperture ring is set in the "A" position (push the button, move it off "A", work the aperture ring back and forth, then return it to the "A" position remembering to push the button again)? In the pic that you posted, it doesn't look like the aperture ring is in the "A" position. . . more like f16 or so. . .
I'd also make sure that the contacts are clean on both the camera body and lens.
The FA* 300/4.5 "focus clutch" actually detaches the AF screw in the lens from engaging the body's screw drive and ID's the lens as an MF lens to the body (that's why Focus Trap works with this lens without shorting the Data Pin). It's also possible that disuse has caused a bad contact internally in the "A" position, and working the ring might either loosen something that might have frozen or re-establish some needed internal contact.
Probably won't make a difference, but it won't cost anything to try. . .

Yeah, tried all of that. Moved the lens in and out of AF mode, fiddled with the aperture for quite some time, did a number of tests, cleaned contacts, all no good.
Good news is, the lens focuses fine in manual and I emailed Eric, who said it would be about $100 to repair.
So I think I'm going to go that route. $100 for this lens is grand larceny.
Thanks for the input folks! Much appreciated.
