A properly bonded 3rd cam should last the life of the lens. You must take care to bond it exactly at the right offset and height or you'll get erroneous readings. Also you have to remove some metal from the rear baffle so the cam will clear. Note that for all functions to work properly all the steps in the cam must be the right length. The best way to do this is to guide yourself by another lens of the SAME speed with a factory 3rd cam. Also, use the lens as a reference for positioning the cam. Use fresh, qood quality 5 minute epoxy, never crazy glue! I've done this on several of my lenses starting about 15 years ago and have never had one fail. It's strictly a DIY thing, never pay someone to do it for you!
