Fujifilm Z33WP has a 10.0MP 1/2.3" (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Sony NEX-5T has a 16.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Bionz processor. Sony NEX-5T's sensor provides 6MP more than Fujifilm Z33WP's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the Z33WP and NEX-5T sensor size comparison.
As seen above, Sony NEX-5T has a 13.0x Larger sensor area than Fujifilm Z33WP. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
