SIRUI 50mm F1.8 Anamorphic 1.33X Lens Instructions

Product Overview

The SIRUI 50mm F1.8 Anamorphic 1.33X lens is a high-quality optical tool designed to provide a cinematic 2.4:1 aspect ratio on APS-C cameras. By expanding the horizontal field of view by 33% compared to traditional 50mm lenses, it allows users to capture professional-grade footage with unique anamorphic characteristics, such as distinct lens flares and a shallow depth of field.

Components of the Lens

The lens features a robust aluminum housing and precision-engineered glass elements. Key components include the top lens cap, focus ring for manual adjustments, an indicator ring for precise settings, an aperture ring to control light intake and depth of field, and a bottom lens cap for protection when not in use.

Lens Set-Up Instructions

To attach the lens to your camera, align the white dot on the lens with the corresponding white dot on the camera mount. Insert the lens into the mount and rotate it in a clockwise direction until it clicks into place. To remove the lens, press the camera's lens release button and rotate the lens in a counter-clockwise direction.

Precautions for Normal Use

To ensure the longevity of your lens, please follow these guidelines:

• Avoid long-term exposure to humid environments, which can lead to mold and rust. Store the lens in a dry, well-ventilated cabinet.
• Do not touch the glass surface with your fingers. Use a professional lens cleaning cloth or brush to remove dust or fingerprints.
• Avoid using the lens in heavy rain or near water, as moisture can damage the internal components and void the warranty.
• When moving the lens between environments with significant temperature differences, allow the lens time to acclimate to the new temperature to prevent internal condensation.
