The entrance pupil position is the correct
position of the axis of rotation when making
a panorama image by combining individual
images of a scene.
The result of our constant striving for ultimate performance,
the HCD 35-90mm zoom lens combines our advanced optical
design models with a new aspheric lens element design to
create what we think is the highest performing zoom lens on
the market today.
