While the same as your back to back caps, I have a different intent in mind. I won't store lenses back to back on a siamesed cap ... that makes the total package too long for my bag/slot design and means hunting for the right lens as part of a lens pair, can mean even more bits to juggle. I tried it with my Leica gear some years ago but didn't like it very much.
The purpose for the back to back rear caps is to enable changing the lens more quickly and reducing the amount of bits juggling you have to do in the operation of "pull out a lens - pull the rear cap - put a cap on the lens you just took off the camera". With back to back rear caps, you twist a lens onto the one you just pulled from the bag, then hold the cap and twist the other right off, barely moving your hands. The lens that goes in the bag has a cap on the rear in the end, with a siamesed rear cap opening unused. Because I will not depend on the caps to stick together with the weight of two lenses bearing on the cement joint, almost any cement will do (epoxy, rubber cement, cyanoacrilate ...). Their join could always be reinforced with a glued in reinforcing ring too. Godfrey On Oct 23, 2006, at 8:23 AM, Shel Belinkoff wrote: > I've done that for years, and it works great.
