Metabones Contax N Lens to Sony E-Mount T Speed Booster ULTRA 0.71x Adapter, Black Satin Exterior/Black Matte Interior

From the pioneers of lens adapters, Metabones introduces the high-quality Contax N Lens to Sony E-Mount T Speed Booster ULTRA 0.71x Adapter. This innovative product is a game-changer for photographers who own the legendary Carl Zeiss optics in Contax N-Mount and wish to utilize them with Sony E-Mount mirrorless cameras.

This durable adapter is built on the proven success of Metabones' past products, offering phase-detection autofocus on a range of Sony cameras including A9, A7R Mark III, A7 Mark III, A7R Mark II, A7 Mark II, A6500, and A6300. The autofocus not only provides pinpoint accuracy but also surpasses the AF speed of the original Contax N series AF cameras.

The compact and versatile adapter allows users to experience the ergonomic feel of the original Contax N1 camera. It enables the use of the lens' own aperture ring in aperture priority and manual exposure modes on A9, A7 series, A6500, and A6300. Fully automatic exposure and shutter priority are also available.

The adapter features a customizable button that can be assigned to more than 50 different functions on an A9, A7 series, A6500, or A6300 camera, including depth-of-field preview. The adapter's interior is flocked with felt to minimize internal reflection, and it includes a tripod foot compatible with Arca-Swiss style quick release.

The Speed Booster ULTRA uses an advanced 5-element/4-group optical design by Caldwell Photographic Inc., incorporating ultra-high index tantalum-based optical glass to achieve extraordinary optical performance. It effectively reduces the crop factor of APS-C cameras from 1.5x to 1.07x, allowing for improved corner sharpness, distortion, and reduced vignetting.

The adapter is well-corrected for use with virtually all full-frame SLR lenses regardless of exit pupil distance, making it an excellent choice for professional-grade f/2.8 zoom lenses such as the Carl Zeiss Vario-Sonnar T*2,8/17-35. High-speed fixed focal length lenses such as the Carl Zeiss Planar T* 1,4/50 and Carl Zeiss Planar T* 1,4/85 will be transformed into f/1.0 lenses with excellent contrast and resolution.

The Metabones Contax N Lens to Sony E-Mount T Speed Booster ULTRA 0.71x Adapter is a testament to the enduring legacy of Contax and Carl Zeiss, allowing photographers to leverage the latest mirrorless camera features with some of the finest autofocus optics ever made.
