I have a Nikon 20-35 whose flex circuit I managed to tear while attempting to remove the bayonet. Took surprisingly little force to do so, so little that I thought the aperture coupling lever was preventing it from coming free. Anyway, I now have a very nice but very manual-focus AF lens that I think is worth repairing. I called Precision Camera and they don't even list parts for it. Checked eBay, and it turns out I would have much better luck if I'd taken a hammer to the front element; no joy on a flex circuit. Does anyone have a 20-35 flex circuit or a mechanically junked 20-35 that I could salvage? I really like this lens and I'd hate to have to sell it for parts.
