field of view – Apparent size of subject in two different cameras with the same resolution and focal length (or FOV)


Consider two cameras with the same resolution (let’s say 640×480) and focal length (or FOV) looking at the same subject. Let’s assume that the subject is in focus in both cameras.

Will the image of the subject be the same size across both cameras? That is, if one camera shows the subject as occupying a grid of 10×10 pixels, will the other camera give the same result?

Are there other properties that will affect this?
