A77 EVF question
I'm wondering how much each individual step is for the diopter adjustment setting.
My a77 20 steps for the adjustment dial and I've seen various different numbers but no official spec: Gary Friedman said -3 to +1 diopters, other sites say -4 to +3and DXOmark says -4 to +4..
The most logical one would be -4 to +3 and each step is 1/3rd a step (0.33).'
EDIT: Checked the user manual and found a brief spec saying -4 to +3. Though my question remains about the individual steps as I'm unsure how that is fit into 20 steps of adjustment.
