Metabones Sony A-Mount Lens to E-Mount Camera ULTRA Speed Booster, Matte Black

The Metabones Sony A-Mount Lens to Sony E-Mount Camera ULTRA Speed Booster in Matte Black is a high-quality, innovative tool that enhances your photography experience. This advanced device improves upon its predecessor with a sophisticated 5 element/4 group optical design. It incorporates ultra-high refractive index tantalum-based glass, ensuring improved sharpness and reduced distortion and vignetting for superior image quality.

This versatile Speed Booster ULTRA allows a full-frame Sony A-Mount lens to be seamlessly mounted to an APS-C format E-Mount camera. In doing so, it significantly increases the angle of view and boosts the maximum aperture by approximately one f/stop. This feature is particularly beneficial when a lens designed for full-frame sensors or 35mm film is mounted to a camera with an APS-C sized sensor.

The Speed Booster ULTRA expertly condenses light from the lens and projects it onto the APS-C sensor. This allows the sensor to utilize all of the lens' light, effectively reducing the crop factor of an APS-C E-Mount camera from 1.5x to 1.07x. This results in a full-frame angle of view with an APS-C sensor, broadening your photographic possibilities.

In addition to enhancing the angle of view, the Speed Booster ULTRA also increases the maximum aperture by one f/stop. This makes the lens more effective in low-light situations and enables the creation of a shallow depth of field, providing you with more creative control over your images.

Constructed with precision-machined brass and chromium plating on both the camera body and lens side of the booster, this durable device ensures smooth mounting and long-lasting use. It features a detachable tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads, adding to its versatility.

While the lens will fit physically, note that automatic diaphragm (AE metering) or other auto functions are not retained using this speed booster. However, a built-in aperture control ring enables manual control of aperture from the speed booster, offering you more flexibility in your shooting.

Please note that these speed boosters are only 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. This compact, innovative device is an essential tool for photographers looking to maximize the potential of their Sony A-Mount lenses on E-Mount cameras.
