Well, looks like both lenses will travel cross country to repairs center tomorrow. The two sensor design for aperture ring is classic and proven design (e.g. old mechanical mouses detected direction of movement in the same way). If it only wasn't susceptible to dust... However, I'm surely not going to venture into opening the lens myself and trying to clean stuff inside. I'd estimate it at one in a million chance lens would survive me opening it ;-)
