Metabones Rollei QBM Lens to Fujifilm X-Mount Camera Speed Booster ULTRA

If you're seeking to enhance your photography experience, the Metabones Rollei QBM Lens to Fujifilm X-Mount Camera Speed Booster ULTRA is a game-changer. This advanced piece of equipment is designed to elevate the performance of your full-frame Rollei QBM lens when mounted on an APS-C format X-Mount camera.

The Speed Booster ULTRA is engineered with a 5 element/4 group optical design, incorporating ultra-high refractive index tantalum-based glass. This innovative design ensures improved sharpness, reduced distortion, and minimized vignetting, delivering superior image quality.

The Speed Booster ULTRA not only increases the angle of view but also boosts the maximum aperture by approximately one f/stop. This feature allows your lens to capture more light, making it more effective in low-light situations and enabling the creation of a shallow depth of field.

When a full-frame lens or 35mm film lens is mounted on an APS-C sized sensor camera, it transmits a larger area of light than the smaller sensor was designed to accept. The Speed Booster ULTRA condenses this light and projects it onto the APS-C sensor, allowing the sensor to utilize all of the lens' light. This effectively reduces the crop factor of an APS-C E-Mount camera from 1.5x to 1.07x, producing a full-frame angle of view with an APS-C sensor.

Please note that while the lens will fit physically, automatic diaphragm (AE metering) or other auto functions are not retained using this speed booster.

The Metabones Speed Boosters are crafted with precision-machined brass with chromium plating on both the camera body and the lens side of the booster. This ensures smooth mounting, a quality aesthetic, and long-lasting durability. The interior is matte black to reduce internal reflections, and the exterior boasts a black satin finish to match most camera bodies and lenses.

This adapter also features a detachable tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads. The speed booster is designed to reach infinity focus while maintaining the correct registration distance required to maintain the optical quality of CRC lenses or lenses with floating elements.

In summary, the Metabones Rollei QBM Lens to Fujifilm X-Mount Camera Speed Booster ULTRA is a high-quality, precision tool that enhances your camera's performance, delivering professional-grade images with high contrast and resolution from the center to the edges.
