How to lock in position value of Camera

[#1]

Hi,

I'm simply trying to move a camera laterally down a page (which is in 3D mode), but it zooms in and out unnecessarily between the two keyframes which gives it an unnatural and ugly effect. Is there a way to lock in the z-value of the camera in between keyframes?

Show us with video screen capture making it. But first try making it but from values in layer options, not from composition panel dragging it with mouse.
