Actually, and Bart will probably have to change his POV on this as I'm
100% correct, the most important factor for choosing ANY binocular set
is inter-ocular distances. This will determine if you can use them AT
ALL. No other aspect of a given optical design matters if you cannot
use both eyes. Steiner has several units that are not compatible with
all users.

What if the distance is adjustable... like on most binoculars. I think they
invented that about the same time they came up with adjustable dioptres.
