OK, I've done some crude calculations on the subject, and this is what I've found:
(120-(4*X))*X
- X is the thickness of the border that isn't visible in the viewfinder.
- The edge of a 35mm film is 120mm (24+24+36+36).
- Subtract the four corners once from two of the sides so the corners arent'
calculated twice. (Then we have 36+36+(24-2X)+(24-2X).)
- Multiply by the thickness of the border.
If this calculation has been set up correctly (I don't think it's 100%, but close
enough), then the gap between the viewfinder and the film-area is 0.2182mm...
(120-(4*0.2182))*0.2182 > (120-0.8728)*0.2182 > 119.1272*0.2821 = 25.993555 mm2
(And I actually bothered to set this up? Sometimes I impress myself...)
