4. Упутство за употребу

4.1 Achieving Cinematic Widescreen

The 1.33x squeeze factor of this anamorphic lens allows you to capture a wider horizontal field of view than a standard spherical lens. When shooting in a 16:9 aspect ratio, the lens compresses the image horizontally. In post-production, you will need to "desqueeze" the footage by a factor of 1.33x to achieve the classic 2.4:1 cinematic widescreen look.

4.2 Manual Focus and Aperture Control

This lens features manual focus and a de-clicked aperture ring for smooth adjustments during shooting. The focus throw is designed for precise control, making it suitable for cinematic pulling.

• Прстен за фокусирање: Rotate the focus ring to achieve sharp focus on your subject. Utilize focus peaking or magnification features on your camera or external monitor for accuracy.
• Прстен бленде: Adjust the aperture ring from F1.8 to F16 to control depth of field and exposure. The de-clicked design ensures silent and seamless transitions.

4.3 Cinematic Effects: Blue Flares and Oval Bokeh

The SIRUI 35mm Anamorphic Lens is renowned for its distinctive blue horizontal flares and oval-shaped bokeh, which contribute significantly to the cinematic aesthetic.

• Blue Flares: When light sources hit the lens, they produce characteristic blue horizontal streaks, adding a dramatic, sci-fi feel to your footage. The intensity of these flares can vary with aperture settings.
• Oval Bokeh: Out-of-focus highlights appear as elongated ovals rather than circular shapes, creating a unique background blur that is a hallmark of anamorphic cinematography.
