I’m considering swapping out cameras and want to make sure the new ones have a similar field of view.
Current Camera:
Focal length: 3.6-10mm
Field of view: 100°-45° Horizontal, 53°-25° Vertical
New Camera:
Focal length: 4.1-12.3mm
Field of view: Horizontal 109.9°, Vertical 59.9°
The new camera’s focal length is slightly longer (0.5mm more), but the field of view is a bit wider. Do you think this difference will have any noticeable impact, or will the slightly larger field of view offset the longer focal length? Any calculations or insights would be appreciated.

The focal length directly affects the field of view, so there isn’t really an offset between the two.
Thanks for clarifying! Given the larger field of view on the new camera, it sounds like I shouldn’t worry too much. I’m thinking the new field of view will be the same or maybe even a little wider. Does that sound right? Appreciate the input!

Yes, both lenses are varifocal, and their ranges overlap. The new camera can potentially have a wider field of view, but if the current camera is adjusted within that range, you could match the same field of view on both.
