3.2.8.4 Computing the Magnification
− SLR connections, 2.5× / T2 adapters:
The magnification of the image on the 35 mm film M
film
is the product of objective magnification M
obj
and the factor of the T2 adapter 2.5×.

, = 10×:
The magnification of the image on the 35 mm film M
film
is calculated from the objective magnification

,, the focal length of objective f
