Someone here is ususally knowledgable!
I sent a set of fairly expensive set of Pentax binocs back to have the eye cups tightened. They damn near retract under their own weight. In classic modern BS form they won't touch them without the original receipt. They also won't offer a repair for a fee. THIS IS WHY I CURRENTLY ONLY PURCHASE LEUPOLD PRODUCTS!!!! (shameless plug) and quite frankly the 2 pairs of relatively inexpensive McKenzie Leupold binos I bought the kids are nicer than these anyway... but I digress. Short of a a crude mechanical fix, how can I get these eye cups tightened up? I am considering a piece of large diameter heat shrink or a produce rubber band (you know, a crude mechanical fix.) At that point they wound't retract, but I am not sure I would care?
