Aperture Control:
The VILTROX AF 27mm F1.2 Pro features a clicked aperture ring for precise control over your depth of field and exposure.
- Rotate the aperture ring to select your desired f-stop from F1.2 to F16.
- The F1.2 large aperture allows for excellent low-light performance and creates a beautiful, creamy bokeh (background blur), isolating your subject effectively.
Optical Performance and Features:
- Premium Optical Construction: The lens features 15 elements in 11 groups, including high-refractive index lenses, ED lenses, and an aspherical lens, ensuring high resolution and image quality.

6. Maintenance and Care
- Cleaning the Lens: Use a soft, clean microfiber cloth specifically designed for optical surfaces to gently wipe away dust and smudges. For stubborn marks, use a small amount of lens cleaning solution applied to the cloth, not directly to the lens.
- Storage: When not in use, store the lens with both front and rear caps attached in a dry, cool place, away from direct sunlight and extreme temperatures. If storing for extended periods, consider using a dehumidifier or desiccant to prevent mold growth.
- Avoid Contaminants: Keep the lens away from sand, dust, and water. If exposed, clean immediately and thoroughly.
- Handling: Always handle the lens by its barrel, avoiding touching the glass elements.
