Field of View Calculator

Compare 12X, 20X and 30X optical zoom at the exact distance your camera will sit, before you buy.

Getting Started

The right zoom depends less on how big your room is than on how far your camera sits from the people you’re filming. A lens that frames a speaker perfectly from 20 feet can leave them looking small from 60, and too much zoom in a tight room can cut people out of the shot.

For the most accurate result, measure from where the camera will be mounted to where your subject will stand or sit. Still planning the room? Pick the preset closest to your space and adjust from there.

Approximate scene width with each lens fully zoomed out, calculated as 2 × distance × tan(horizontal FOV ÷ 2). Zooming in narrows the shot from there.

Need more reach? Use SuperZoom.

On 4K models with SuperZoom, switching the output to 1080p lets the camera crop into its 4K sensor. That adds up to 2X digital zoom on top of the optical lens while keeping a full 1080p picture.

Available on:

12X optical24Xtotal in 1080p

20X optical40Xtotal in 1080p

30X optical60Xtotal in 1080p

These are planning estimates. The right camera also depends on mounting position, how tight you want the shot, subject size, output resolution and lighting. Not sure which fits? Talk to a PTZOptics reseller or reach our team at 1-833-888-9706.
