Explore the world of photography with the Canon Rollei QBM Lens to Sony E-Mount Camera ULTRA Speed Booster in a sleek matte black finish. This high-quality, durable product is an innovative solution for photographers looking to enhance their Sony E-Mount camera system.
The ULTRA Speed Booster is designed with a 5 element/4 group optical structure that incorporates ultra-high refractive index tantalum-based glass. This advanced design significantly improves sharpness, reduces distortion, and minimizes vignetting, resulting in superior image quality.
This compact and versatile adapter allows a full-frame Rollei QBM lens to be mounted to an APS-C format E-Mount camera. In doing so, it increases the angle of view and boosts the maximum aperture by approximately one f/stop. This feature is particularly beneficial when a lens intended for full-frame sensors or 35mm film is mounted to a camera with an APS-C sized sensor.
The ULTRA Speed Booster condenses light from the lens 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.
The increased maximum aperture of one f/stop makes the lens more effective in low-light situations and able to create a shallow depth of field. This makes it an ideal tool for low light photography and action shots.
The Canon Rollei QBM Lens to Sony E-Mount Camera ULTRA Speed Booster is precision-machined from 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.
This adapter also features a detachable tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads. While the lens will fit physically, automatic diaphragm (AE metering) or other auto functions are not retained using this speed booster.
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.
Experience the power and versatility of the Canon Rollei QBM Lens to Sony E-Mount Camera ULTRA Speed Booster and elevate your photography to new heights.
