When you attach the lens with the same magnification, the number of inches in the image size is smaller, the magnification and the narrower the field of view will be smaller.
Please see the picture below.
I shot the picture with lens, monitor, and focal length under the same conditions.
1/2 inch camera
|
1/2.5 inch camera
|
1/3 inch camera
|
You can realize that the 1/3-inch camera has a narrower field of view than the 1/2-inch camera.
Besides that, when selecting lenses, you need to check the size of the camera’s corresponding image sensor.
Please note that vignetting will occur if you select a lens that is less than the camera’s compatible image sensor size.
A black part (vignetting) is present at the four corners of the screen |
We will also select lenses and cameras that is suitable for your requirements. Please contact our technical advisor for more details.
