Re: optics data

Generally, the "4" means four power (or an image four times larger than if
seen by the naked eye), and the "32" means that the objective lens of the
optics (e.g. "front lens") is 32 mm in diameter.  The higher the power,
obviously the greater the magnification (and the harder to hold a steady
point of aim unless bench rested).  The larger the objective, the more light
will be captured and focused so better operation in low visibility or poor
lighting.

"Zoom" is usually a term reserved for optics with variable magnification
power.
