Other than the zoom, other differences include the 35mm Equivalent Focal Length difference (which may be the difference between the 40x zoom and the 50x zoom), a 920k-dot tilting LCD monitor vs. a 460-k-dot tilting LCD monitor, and optical vs. lens shift stabilization.
Looking at the tech specs from the Fujifilm web site the image sensor appears to be the same in both cameras.
