Enhanced Functionality due
to “Exmor” Technology
Both the HVR-Z7
E and HVR-S270E offer cutting-edge
features, such as the
“Exmor™”technology developed
by Sony, which utili

can eliminate the influence of external noise that
enters the signal chain during transfer to the A/D
converter, resulting in high-quality digital signals with
extremely low noise. This significantly enhances shooting
in low-light environments.
By adopting this groundbreaking technology, the new
1/3-inch 3 ClearVid CMOS Sensor system enables the
HVR-Z7E and HVR-S270E to achieve a low light sensitivity
of just 1.5 lux*.
