Ditto my Fujinon BFL, Geoff. I fact all good quality 7-12 x 40-50mm binos under $500 seem to have about 50 degree afov.
Interestingly the budget models tend to have 60-65 degree fov. E.g. Olympus DPS I vs EXPS, Nikon Action vs Action Extreme.
Maybe that's how you make a mid priced quality bino. Take some cheap ones, reduce the field stop to mask the seagulls, and slap some better coatings on the optics.
