Typically objective lenses on early sights are smaller than modern sights, in these examples the 4×81 would have an objective 36 mm diameter and the 2.5×70 should be approximately 21 mm (relative luminosity is the square of the exit pupil as measured in mm; a 36 mm objective lens diameter divided by the 4× magnification gives an exit pupil ...
Typical modern target shooting diopters offer windage and elevation corrections in 2 mm (0.079 in) to 4 mm (0.157 in) increments at 100 m (109.4 yd).
