Is this binocular an internal Focussing Porro ?...It features a center focus Wheel,but there is no focussing Bridge....
Mayo:
I think you are correct, this is a center focusing porro prism type, with internal focus, so that
means waterproof. No moving bridge.
Looks like they don't have full focus range

The describe the CF s a tweak to their usual 30m to infinity "fixed" focus (i.e. eye accomodation) focus system. Both EPs have the usual IF system to infinity focus the bins.
I suspect it's internal focus with a very limited range to pull the close focus from 30m to 2m.

Interesting idea.
Anyone tried them?
