The following calculators compute the Horizontal Field of View (HFOV) or Effective Focal Length (EFL) of a camera and lens system, for any sensor format. Using the EFL calculator, enables system engineers to find a lens according to pre-determined FOV, which will enable easy search of the relevant product within Ophir’s catalog.
This calculator is used to calculate the FOV(field of view) of an optical imaging system with given parameters. In this section, you need to fill in the Number of Horizontal Pixels , the Number of Vertical Pixels , the Pixel Size(μm) of the sensor, and the Lens EFL (effective focal length).
This Field of View (FOV) Calculator is a tool designed to help you quickly and accurately calculate various aspects of your camera’s field of view based on the dimensions of your camera sensor, lens focal length, and distance to the subject. Follow the step-by-step instructions below to make the most out of this calculator.

25 wrz 2010 · Does your lens use an inner focusing system or is a video or cine lens? Calculate the depth of field (DoF), angle/field of view (AoV & FoV), the equivalent lens and aperture on other formats, and more.
(2) Minimum object size is based on the specified range. (3) Maximum range is based on the specified object size. (4) Actual FOV will be slightly larger than calculated value.
