[QUOTE="dieselnutjob, post: 717008, member: 47318"] I think that I have resolved this. I found a youtube video on this exact lens describing how to dismantle and re-assemble it, so got the screwdrivers out. It looks to me like someone has been there before me as a I found red blobs of paint on some of the screws inside and some handwriting on one part. Also I found that one of the ribbon cables did not have the locking tab properly and fully pushed home. This is one of the ribbon cables that flexes as the lens is zoomed which is why it was more reliable at some focal lengths than others. I pushed in the locking tab fully and re-assembled the lens and it appears to be working well now. I will have to wait for daylight tomorrow to verify though. [/QUOTE]
