Guys- Miyauchi eyecups may be stiff, but they do fold (all of them). See attached pic. Before we ship, these little 5x32's are as well-collimated (at all IPD's) as the extreme-magnification binoculars we routinely ship. But if one needs a slight tweek, it's user-adjustable. Just like all other <100mm Miyauchi models, there are prism tilt screws located under 4 caps (they look like rivets, but they pry off easily). PM me for more details. Kevin Busarow
