I collect early Japanese extra wide angle binoculars ( 10deg & up ) because they don't make these now .
Most are in the 7x35 format , my all time favorite are a pair of Swift Sport king mark 1 ' the field of view is 630ft at 1000yds or 12 degrees !
I do have some modern wide angle binocular sets but the view can not compare to the 50+ year old super wide's .
Have Fun
