# Projector Lens 16mm

**Special thanks to Dr. Film**

**The standard projection lens for 16mm is the 2".
Lenses can be had from 1" to 4" for most projectors.
The longer the lens, the smaller the projected size image for a
given distance. The 1" lens will project an image approx
twice the size of a 2" lens over a given distance. Unless
you have a very long or short throw to the screen, the 2" or
a 1.5" lens will do the job in your screening room. Check
out ****Screen Size Charts
16mm**** to ascertain your screen size with
various length lenses. **

**Once you determine the length of the lens you need,
you should then considered how much light it will pass to the
screen. This is indicated by it's "F" rating. The lower
the better. An F1.2 will produce a noticeably brighter picture
than an F1.6 **

**Lastly, you must be certain that the diameter of the
lens will fit your projector. For example, Bell & Howell lens
diameters vary from model to model and most manufacturers use
their own diameter. The following table should help you determine
the lens diameter for your machine.**
