[Optical Construction of the AF 75mm F1.8 X]

Impressive Background with
Refined and Wonderful BokehThe subject can be highlighted utilizing the shallow depth of field with the AF 75mm F1.8 X. When it is used wide open, busy backgrounds melt away from the subjects, and the subject such as a person, animal, or food, stands out even if the background is busy. Smooth bokeh created by a 9-blade circular aperture design makes the shallow depth of field expression more dreamy.

Preset Aperture Control Function
Specialized for Video ShootingWith Samyang´s own feature "Preset Aperture Control" function on the "Custom Swith", you can create a video maximizing fujifilm´s own unique look and feel. You can control the depth of field more smoothly without noise and vibration when you record videos in AF mode. Every movement will be expressed more naturally than controlling on Fujifilm´s camera body.
[Samyang´s Guide to Preset Aperture Control Function]
What is Preset Aperture Control Function?
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.
[Recommended Settings for Preset Aperture Control Function]
What is Recommended Settings for Preset Aperture Control Function?
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).
