Metabones Contax Yashica CY Lens to Sony E-Mount Camera Speed Booster ULTRA 0.71x CINE Adapter

How can you enhance your photography experience when pairing Contax/Yashica lenses with Sony E-Mount cameras The answer lies in the innovative Contax Yashica CY Lens to Sony E-Mount Camera Speed Booster ULTRA 0.71x CINE Adapter. This high-quality adapter is designed to not only bridge the compatibility gap between your cherished lenses and a new camera system but also to elevate your photographic results to professional levels.

Crafted with an advanced 5-element/4-group optical design, this Speed Booster ULTRA incorporates ultra-high index tantalum-based optical glass. The result is a significant improvement in corner sharpness, distortion control, and a noticeable reduction in vignetting. The optical prowess of this adapter ensures that your images will maintain their integrity, with crisp details and even illumination across the frame.

The Speed Booster ULTRA's 0.71x magnification factor is a game-changer, effectively reducing the crop factor of DX-sized sensors in Sony E-mount cameras from 1.5x to 1.07x. This transformative feature not only widens your field of view but also increases the maximum aperture of your lens by approximately one stop, allowing for a wider aperture and faster shutter speeds. This is particularly beneficial for low-light photography and achieving a shallow depth of field for that cinematic look.

Moreover, the adapter's utilization of exotic materials pushes the boundaries of glassmaking technology. It is exceptionally well-corrected for compatibility with full-frame SLR lenses, ensuring that even professional-grade f/2.8 zoom lenses, such as the 24-70mm and 70-200mm, perform optimally, transforming them into high-speed zooms with impressive aperture capabilities.

The Metabones commitment to quality is evident in the construction of the Speed Booster ULTRA. Precision-machined brass with chromium plating is used for both the camera-body and lens sides, ensuring a smooth, secure fit and a durable, attractive finish. The adapter's lens side features a robust leaf-spring structure for a secure lens connection, minimizing wear and preventing focus errors and optical misalignments.

In addition to its mechanical excellence, the adapter boasts a matte-black finish to minimize internal reflections, preserving the maximum optical quality of your lens. The Speed Booster ULTRA also integrates industry-leading electronic interfacing technology, allowing for seamless electronic control of the lens' aperture directly from the camera body.

Choose the Contax Yashica CY Lens to Sony E-Mount Camera Speed Booster ULTRA 0.71x CINE Adapter for its unparalleled compatibility, innovative design, and the ability to unlock the full potential of your lenses on a Sony E-Mount camera system. This compact, durable, and versatile tool is an essential addition to any photographer's kit, ensuring that your creative vision is never compromised.
