Just for grins, has anybody actually measured the fov of the SF? Is it really 444' or something else? I notice the Zeiss website lists the HT with a 404' fov and a 62* viewing angle. The Sf says 444' (both for 8x) and lists a viewing angle of 60*. Something does not compute. Sadly websites these days are rife with errors.
Unless the SF measures more than 444', the SF is not the fov market champion. Kruger modestly and incorrectly lists their Caldera 8x as 438'. I've had two, still have one, and they both clocked at 464', or 8.8*.
Just an example of website errors and I'm just curious what the SF actually measures.
SF 8x42 - 444' (@1000 yards) - 148 meters (@1000m) - 8.6° - (64° AFOV)
SF 10x42 - 366' (@1000 yards) - 120 meters (@1000m) - 6.9° - (65° AFOV)
The formula AFOV = FOV x Magnification
I suspect is an approximation that works
best for narrow field telescopes. Probably why
it differs with the real values stated by Zeiss.
Correct me if I'm wrong.
