Metabones Contax Yashica CY Lens to L-Mount CINE Speed Booster ULTRA 0.71x Adapter, Black

After meticulous engineering and design, the Contax Yashica CY Lens to L-Mount CINE Speed Booster ULTRA 0.71x Adapter emerges as a high-quality, professional-grade tool that seamlessly bridges the gap between your cherished Contax/Yashica lenses and the modern L-Mount system used by Leica and Panasonic mirrorless cameras. This innovative adapter not only ensures compatibility with an extensive array of lenses but also enhances the photographic experience by improving image quality.

Crafted with an advanced 5-element/4-group optical design, this adapter incorporates ultra-high index tantalum-based optical glass. The result is a significant boost in corner sharpness, a noticeable reduction in distortion, and minimized vignetting, ensuring that the performance of the attached master lens is always enhanced, never degraded. The Speed Booster ULTRA's 0.71x magnification effectively diminishes the crop factor of DX-sized sensors and Super35 camcorders, transforming it from 1.5x to a more full-frame-friendly 1.07x.

The adapter's utilization of exotic materials pushes the boundaries of glassmaking technology, allowing for compatibility with nearly all full-frame SLR and prime lenses, irrespective of the exit pupil distance. This versatility makes it a must-have for professionals seeking to leverage their existing lens collections.

Metabones, a brand synonymous with quality and precision, ensures that this adapter is built to last. Unlike other manufacturers, Metabones eschews shortcuts, opting for precision-machined brass with chromium plating on both the camera-body and lens sides, guaranteeing a smooth mount, impressive durability, and a refined appearance. The lens side features a robust leaf-spring structure, enhancing the connection between adapter and lens, mitigating wear, and preventing any focus or optical alignment issues.

The adapter's matte-black treatment minimizes internal reflections, preserving the maximum optical quality of your lens. Additionally, the Smart AdapterTM series boasts industry-leading electronic interfacing technology, allowing for true electronic control of the lens' aperture directly from the camera body.

Key features include:
- Brass construction with chromium plating for durability and a secure fit.
- Satin surface finish to match your professional camera and lens mounts.
- Precise fit ensuring no play, gap, or wiggling when the lens is mounted.
- Capability to reach infinity focus while maintaining the correct registration distance for optimal optical quality.
- Electronic integration of the aperture diaphragm, enabling automatic or manual aperture control from the camera body.
- Transmission of EXIF data such as lens identification, focal length, and aperture to the camera.

This Contax Yashica CY Lens to L-Mount CINE Speed Booster ULTRA 0.71x Adapter is the perfect choice for photographers and videographers looking to expand the capabilities of their L-Mount systems without compromising on image quality or build integrity.
