More Tools for FOV Calculation:
Purchasing lenses will lead you to figure out differences between camera field of view and angle of view, how the field of view is calculated, and you will stumble upon further technicalities such as focal length and camera sensors. You have the choice to pick between different cameras with different crop sensors, as well as the option of purchasing full-frame cameras.
Lenses also come with a range of focal length and field of view, with the shorter focal length giving you a wider field of view and vice versa. But what do these terminologies really mean? And how can you calculate the field of view of a camera before getting your card out? Let me make it easier for you.
|Camera Field of View |
|Full-Frame (35mm) FL||APS-C (1.6x crop factor) Equivalent FL|
How To Use:
A simple mathematic way that you can calculate your camera’s field of view angles can be through the following steps.
- Research and find out the specifications of your lens and its camera.
- Using the FOV Calculator Camera tool above, input the values and select your camera.
- Click the “Calculate” button and it will tell you exactly the field of view.
You can also do this using a formula mentioned below:
The formula for angle of view is, where all measurements are in mm is:
Field angle of view = 2 x arctan ((sensor dimension eg: width/(2x focal length)) * (180/Π)
The formula for the field of view is:
Field of View = 2 (Tan (Angle of view/2) X linear distance to the object being captured)
- As per the equations, we can see that field of view also considers the distance between the lens and the subject being viewed through the camera.
- And thus, you are done! Calculating your camera field of view has never been easier than this.
