5.1 Focus Control

The lens features a manual focus ring with a 240° throw. Rotate the focus ring to achieve precise focus on your subject. The wide throw allows for fine adjustments, crucial for cinematic work.

5.2 විශාලන පාලනය

Adjust the focal length using the zoom ring, which has a 100° throw. The parfocal design ensures that your focus point remains consistent as you zoom in or out, eliminating the need to refocus after changing focal length.

5.3 විවර පාලනය

The aperture ring provides manual control over the T-stop, with a 90° throw. The constant T2.9 aperture ensures consistent light transmission across the entire zoom range, simplifying exposure settings.

5.4 Parfocal Performance

The parfocal optical design is a key feature, allowing you to maintain sharp focus on your subject even when changing the focal length. This is particularly beneficial in dynamic shooting environments where constant refocusing would be disruptive.

5.5 Imperceptible Breathing

The lens is designed to exhibit minimal focus breathing. This means that when you adjust focus, the field of view remains stable, preventing distracting changes in composition and allowing cinematographers to concentrate on their subject.
