The VILTROX DG-GFX 45mm Macro Extension Tube is designed for photographers who require higher magnification and closer focusing performance when shooting with Fujifilm G-mount medium format cameras. By increasing the distance between the lens and the camera sensor, this extension tube allows lenses to focus significantly closer, making it ideal for capturing fine textures, product details, and high-resolution macro photography. Featuring full electronic communication, the DG-GFX 45mm supports auto focus, TTL metering, aperture control, and EXIF data transmission. This ensures stable and seamless communication between your camera and lens, allowing photographers to continue using standard shooting modes while expanding macro shooting capabilities. Constructed with a precision-machined metal bayonet, the extension tube provides a secure and stable connection between camera and lens. The durable metal structure with surface plating treatment enhances reliability and ensures consistent performance during professional shooting sessions. The 45mm extension tube delivers stronger magnification compared to shorter extension tubes, making it especially suitable for photographers who require higher macro reproduction ratios. It can also be combined with the DG-GFX 18mm extension tube (sold separately) to create a 63mm extension length, offering even greater flexibility for specialized macro work. Designed without optical elements, the extension tube maintains original image quality without introducing additional distortion. Its compact and lightweight design makes it easy to carry, providing photographers with a practical macro solution for studio, commercial, and creative photography.
