Under the umbrella of innovative camera accessories, the Metabones Canon FD Lens to Sony E-Mount Camera ULTRA Speed Booster stands out as a high-quality, durable, and versatile tool. This compact device is designed to seamlessly convert a full-frame Canon FD lens to an APS-C format E-Mount camera, enhancing your photography experience.
The ULTRA Speed Booster boasts a sophisticated 5 element/4 group optical design, incorporating ultra-high refractive index tantalum-based glass. This advanced design ensures improved sharpness, reduced distortion, and minimized vignetting, delivering crisp and clear images every time.
One of the key features of this speed booster is its ability to increase the angle of view and the maximum aperture by approximately one f/stop. This is achieved by condensing the light from the lens and projecting it onto the APS-C sensor, allowing the sensor to utilize all of the lens' light. This innovative process 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.
The ULTRA Speed Booster not only enhances image quality but also improves lens performance in low-light situations. The increased maximum aperture allows for faster shutter speeds and a narrower depth of field, making it an ideal accessory for portrait and low-light photography.
Constructed with precision-machined brass and chromium plating on both the camera body and lens side of the booster, this adapter promises smooth mounting and long-lasting durability. It also features a detachable tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads.
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 ULTRA Speed Boosters are fully compatible with mirrorless cameras housing APS-C or smaller image sensors. They will physically fit the Sony full frame mirrorless cameras, but the camera must be set in Crop Mode to fully support the speed booster's functions. With the Metabones Canon FD Lens to Sony E-Mount Camera ULTRA Speed Booster, you can unlock the full potential of your camera and lens.
