Any binoculars with a large AFoV *and* exit pupil?

From the top of my head the closest I can suggest ( i.e exit -pupil of 5.6mm and AFOV of 64 degrees ) is the Zeiss Victory 10 x 56.
You certainly won't be forfeiting anything in terms of "lost brightness" with these as opposed to any other binocular with an exact 6mm exit -pupil.
Regards , Kenny.

I know that "high quality" might be debatable here but there is always the Russian Borderguard PNB 2
These are 15 x 110 with a 6 degree TFOV !
Hardly the kind of thing you'd want to take along to a picnic though :-)

"High quality" is a relative term. Means different thing to different people. Leica, Swarov and Zeiss certainly make some of the best binos available. I can think of one model on the opposite side of the price range of what Kenny mentioned that's close to your specification: The Oberwerk 12X60. 68.4 deg APFOV and $109. There are very few situations I can think of where I would need exit pupil larger than 5mm: Mag 6.5+ skies. I have to drive 5 hours or more to central PA to find it. Under other conditons exit pupil of 4-5mm provides darker sky background prefered by most.

Erik, I may end up getting the 12x60mm Oberwerks soon. 12x and 15x Oberwerks will work well to keep me satisfied while I save money for a top of the line pair.
