On the Preset Aperture Control function, the aperture blade operates smoothly like a "De-clicked lens", which is advantageous for video recording.
Fujifilm cameras are engineered to control the aperture according to the minimum exposure value(F-stop), so when the camera controls the aperture, it blinks momentarily to set the proper exposure.

AF 75mm F1.8 X intentionally disconnects the communication with the camera body and the lens itself on the Preset Aperture Control function, so it is possible to smoothly adjust the exposure without flickering. ISO and shutter speed are adjusted according to the changed exposure by controlling the aperture, so the exposure value can be changed even with the 1/2 F-stop.

The Preset Aperture Control function operates only when shooting video(Movie mode) and the focusing mode of the camera is set to AF mode. Please set the aperture at f/1.8 before switching the "Custom Switch" to "Mode 2. It is recommended to set the "Exposure mode" as A mode (Aperture Priority AE) or M mode (Manual Exposure).

[What is Dolly shot?]

A dolly shot, also referred to as a tracking shot or trucking shot, is a camera movement technique used by cinematographers to track and follow a subject in motion. To achieve this, the camera is mounted on a device called a "dolly," which facilitates smooth tracking movement. The dolly can move in front of, behind, or alongside the subject, which can be a person, a location, a product, or any other object of focus in the frame. Through this, you can control the emotional distance between the subject and the viewer by highlighting the audiovisual and dramatic effects.

[How to take a Dolly Shot simply by handheld]

Tip. If the moving distance is long, the camera may shake, so please shoot at a focal length between 35 and 100mm.
1. Stand at a distance of about 1.5 to 2 meters away from the subject.
2. Set the custom switch to MF and Mode 3 and adjust the focal length to about 100mm.
3. After focusing on the subject, set the aperture to F8~16.
4. Slowly turn the zoom ring to the left (towards the wide-angle end) while using your upper body and arms to move the camera toward your subject.
5. Dolly Shot complete!
※ When shooting from a farther distance from the subject, use a cart or gimbal for more stable shooting.
