[Quicksand]

I don't want to lose my lens caps, so I use those "keepers" or "leashes" that are really cheap -- you know, with an adhesive disk that attaches to the lens cap, and a string and an elastic loop that goes around the corresponding lens.

Dang, but I HATE those things. Even on my lumpy lenses (e.g. Super Takumars) the elastic loops are forever sliding around and getting caught in focus/zoom rings, extending/contracting barrel segments, aperture rings, etc. They even get stuck on the bayonet mount when some lenses are removed, especially the straight-as-a-beer-can F and FA lenses.

I don't think the two improvement ideas I have had so far are very practical:

(1) a "shock collar" of sorts that delivers a mild electrical shock to the lens cap if it tries to wander off too far, causing it to yelp and return home; and

(2) inspired by gas station restroom keys, attaching some kind of large object like an old steering wheel to the lens cap to prevent it from being overlooked or tucked into a pocket.

Does anyone have any more practical ideas? I don't want to overcomplicate things, but I'm getting annoyed.
