5.3. Lens selection - Field of View calculation
In the section of “Resource” on the Opto Engineering website, a Lens selection tool can assist to
find a suitable lens based on the object size and the camera used.
In the table below are summarized the angular Field of view of kit lenses considering the detector
size of kit camera.
