When using a lens with the same magnification, the smaller the number of inches in the image size, the larger the magnification and the narrower the field of view.
Take a look at the pictures below.
The lens, monitor, and focal length are taken under the same conditions.
1/2 inch camera
|
1/2.5 inch camera
|
1/3 inch camera
|
You can see that the 1/3 inch camera has a narrower field of view than the 1/2 inch camera.
Also, when selecting a lens, it is necessary to check the compatible image sensor size of the camera.
Please note that if you select a lens that is smaller than the camera’s compatible image sensor size, a phenomenon called vignetting may occur.
You can see black areas (vignetting) in the four corners of the screen. |
