Default Re: 35 Lux Asph falling apart - help

OK, so the part that's loose is the lens barrel itself which normally moves anyway when you focus. I assume the 2-3mm is axial - front to back?

Sounds like the attachment of the lens barrel to the front of the inner helicoid is coming apart, maybe a loose retaining ring, and at some point, it will unscrew completely and send the lens barrel earthwards. I doubt it's doing your images much good either.

Something to fix sooner rather than later, I would say.
