tracking zooming shot

i have problem with syntheyes regarding my shot

my shot is zooming shot taken from focal length exactly 35 to exactly 18.
the problem is when i calculate, the focal length is detected as 57 to 35, since theres no zooming with estimate, how am i supposed to solve this porblem?

anyone have a suggestion or having similiar problem?

is your footage shot with a full frame sensor or does any crop factor apply?

full frame

it is a full frame sensor without any cropping or editing
its taken on a tripod, the current error value is 0.8. actually i'm quite satisfied with the result, the gridline matched perfectly with the footage, but the focal length detected in syntheyes and the real life focal length difference make the perspective does not match
