I am curious where you are getting this data on the Minox. Their website lists FOV @ 5 power as 7.6 m at 100m, or 22.8 ft at 100 yds, but you give the value of 24.9 ft at 100 yds. Did you measure the FOV on a sample ZP5 yourself, or do you have another source of data, or...? FWIW, a Minox engineer from Germany told me that their published weight of 970g is incorrect (based on early CAD designs), and the actual production weight is 995g (=35 oz), so their tech specs online do have errors. Just wondering if their published FOV is an error as well...
EDIT: I think I see what you did... you likely just converted the 7.6 m spec from Minox to feet, giving approximately 24.9 ft. But the spec is at 100 meters = 109.36 yards,
and NOT at 100 yds as quoted. Similarly, the Schmidt FOV is 7.8 m at 100 m, which is (extremely close to) 23.4 ft at 100 yds, rather than the (amazing) 25.6 ft at 100 yds.
