Since Eastland does not show depth of field for the 75mm lens below 1m, we can do something like this: 75mm at 1m: 0.993m to 1.006m (i.e. 1.3 cm) 90mm at 1.2m: 1.19m to 1.21m (i.e. 2 cm) Both wide open, i.e. f1.4 for the 75mm and f2.0 for the 90mm. In practice, this means that in either instance, if you focus on the pers= on's eyes, their ears and the tip of their nose will be out of focus.
