Metabones Contax Yashica CY Lens to Micro Four Thirds Speed Booster ULTRA x0.71 CINE Adapter

Enhance your photography experience with the Contax Yashica CY Lens to Micro Four Thirds Speed Booster ULTRA x0.71 CINE Adapter. This high-quality, durable adapter is designed to convert Contax/Yashica lenses to fit Micro Four Thirds camera systems, making it a versatile addition to your photography gear.

Incorporating an innovative 5-element 4-group optical design, this adapter uses ultra-high index tantalum-based optical glass, optimized specifically for the Micro Four Thirds sensor and filter stack. The result is an astonishing level of performance that sets a new standard for focal reducers.

The Speed Booster ULTRA m43 magnifies by 0.71x, effectively reducing the crop factor of mirrorless Micro Four Thirds mount cameras from 2.0x to 1.4x. This makes it an excellent tool for telephoto photography, providing a wider field of view and increased low-light performance.

The ULTRA design utilizes exotic materials at the forefront of glassmaking technology, resulting in near-perfect correction for use with all full-frame SLR lenses, regardless of aperture. It also works exceptionally well with many DX and APS-C format lenses, provided the image circle of the lens is large enough.

The optical performance of the Speed Booster ULTRA m43 is so superior that it improves the MTF of any lens attached to it. Even the latest generation of ultra-high performance SLR lenses, such as the Zeiss Otus series, can be enhanced by adding a Speed Booster ULTRA m43.

The adapter features a strong leaf-spring structure on the lens side, strengthening the adapter-lens connection and ensuring tightness of the lens. This helps to reduce wear and prevent focus errors and optical alignment issues.

Metabones, the manufacturer of this adapter, is recognized among professionals and enthusiasts for its design and workmanship. The adapter uses precision-machined brass with chromium plating on both the camera-body and the lens sides, ensuring smooth mounting, great appearance, and durability.

The matte-black treatment used by Metabones keeps internal reflection to a minimum, maintaining the maximum optical quality possible with the lens. This adapter is part of Metabones' new Smart Adapter series, which incorporates industry-leading electronic interfacing technology from Canada, allowing true electronic control of the lens' aperture directly from the camera body.

In summary, the Contax Yashica CY Lens to Micro Four Thirds Speed Booster ULTRA x0.71 CINE Adapter is a compact, innovative, and versatile tool that enhances the compatibility and performance of your Contax/Yashica lenses with Micro Four Thirds camera systems.
