Thanks for those interesting comparisons, Steve.
I almost didn't read this thread because it was labeled "6-7x
COmpact Binocular comparison," and with large hands and typical cloudy skies, "compact bins" are not my cup o' tea.
But when I actually read your OP, I realized that you weren't writing about true compacts, in the marketing sense of the word, but rather 6-7x
midsized bins.
Most manufacturers, stores, and reviewers designate bins below 30mm aperture as "compacts"

Here's Steve Ingraham's review of several compact bins:

The ZR 7x36 ED2 is not even "compact" in the generic sense of the word, being only 7/10 of an inch shorter than the full sized ZRs.
Compacts are what Ingraham nicknamed "jewelry bins" (literally, in the case of Swaro crystal compacts, which are studded with diamond crystals):

Notice the Swaros are called "pocket bins." Someone on another thread thought pocket bins should be made into a separate category rather than being lumped in with compacts, particularly reverse porros, which don't easily fit into most shirt pockets.
Not to be schoolmarmish (that job's already been filled elsewhere
, but I would like to see a standardization of binocular terminology so that when someone sees the word "compact bin" in a thread title or review, he knows the discussion is about reverse porros or roofs below 30mm aperture and not a 7x36 midsized bin that's almost 6 inches long!
