Newly-developed lens unit
The newly-developed lens unit features 14 elements in 10 groups, including 3 prisms. This new lens effectively suppresses ghosts, flare, and purple fringing. An aperture mechanism is also included for improved resolution characteristics.
Aperture mechanism (2 stop)
THETA Z1 is equipped with a 2 stop aperture mechanism. It enables aperture settings from maximum F2.1, F3.5 to F5.6. Closing down the aperture in bright locations can improve the resolution at the edge.
