question about zoom

talldude123 · 09-06-2006, 11:42 PM

My digital camera (Polaroid i532) has a 3X optical zoom. But if I look close up at the zoom, it says "3X Optical Zoom Lens". Then, in very small writing at the bottom, it says:

"5.95-17.14mm F2.8-4.8"

What do those numbers mean? The amount of MM that the optical lens zooms in and out, and the focus rate?

5.95-17.14mm is the Field of View (zoom range)

F2.8-F4.8 is the change in aperture at wide to telephoto in the zoom lens.

2.8 lets more light in while F4.8 lets less light in.
