Viltrox AF 28/4.5 XF X-Mount AF Lens Features

The built-in Voice Coil Motor (VCM) delivers fast, accurate and quiet autofocus, and at just 60g it’s an easy addition to any camera kit.
The lens features an innovative slide-open mechanism that transforms operation: a simple slide opens the lens for instant access, eliminating the need for a traditional cap while protecting it from dust and scratches.

“The fast and safe operation encourages natural creativity and makes every moment capture-ready,” said Dr. Kahn Wang, GMD of Viltrox.
“True freedom is when there are no barriers between vision and execution. By fusing nostalgic optics with cutting-edge engineering, we have created not just a lens, but a new creative instinct.”
With a focal length equivalent to 42mm, the Viltrox AF 28/4.5 XF offers a versatile perspective perfect for capturing everyday moments, making the most of the camera’s film simulation capabilities. It’s like getting the best of both worlds: a wide-angle perspective for capturing landscapes and the versatility of a standard lens for portrait photography.
It also features an octagonal aperture, which allows it to capture unique light beam effects with backlit point light sources. Whether you’re capturing bustling cityscapes or natural moments, this lens makes it easy to achieve the aesthetic you want without time-consuming post-processing.

The sleek silver-grey metallic body seamlessly blends classic and modern aesthetics with a refined finish and smooth lines, while the front lens is treated with a water- and oil-repellent coating and is secured in a precision-engineered aluminum mount.
