Metabones MB_CN-E-BT1 (MB_CN/E/BT1, MB_CN_E_BT1, MB_CN-E/BT1, mb_cn-e-bt1) Contax N Lens to Sony E-mount T Smart Adapter

Owners of legendary Carl Zeiss optics in Contax N-Mount have long demanded a trusted migration path to mirrorless cameras. With the advent of Metabones® Contax N-Mount to Sony E-Mount Smart Adapter, the longing is over.

Built upon the foundation of Metabones' past success, phase-detection autofocus on A9, A7R Mark III, A7 Mark III, A7R Mark II, A7 Mark II, A6500 and A6300 not only offers pinpoint accuracy but also AF speed significantly surpassing the original Contax N series AF cameras. (Tailored to single-lens reflex cameras with a traditional phase-detection autofocus system, Contax N lenses are not compatible with contrast-detection autofocus mirrorless cameras such as A7S Mark II.)

Get a glimpse of the ergonomic experience of the original Contax N1 camera by using 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.

A customizable button on the adapter can be assigned to more than 50 different functions on an A9, A7 series, A6500 or A6300 camera, including depth-of-field preview. Putting that button on the hand-grip side would have matched a genuine Contax N camera, but since that would have been next to Sony's lens release button, we opted to place this customizable button on the other side of the adapter instead, right where the thumb of your left hand is.

The workmanship and attention to detail are evident from the signature Metabones design and the two electrical contacts carrying power, which are thicker in the same way as a genuine Contax N series autofocus camera. The inside of the adapter is flocked with felt to minimize internal reflection. A tripod foot compatible with Arca-Swiss style quick release is included.

Metabones has a proven track record of firmware stability and timely firmware support. Firmware is user-upgradable via the adapter's micro USB port.

Metabones adapters relay distance information from the lens to the camera body to enable full 5-axis in-body image stabilization of the A9, A7 Mark III series, A7 Mark II series and A6500. (The Contax 645 Makro-Planar 4/120 lens does not report distance information and supports only 3-axis in-body image stabilization.)

Contax made history by offering the world's first full-frame digital camera, Contax N-Digital, in 2002. All Contax products had been discontinued by 2005, leaving some of the finest autofocus optics ever made in search of a successor. None of these lenses feature optical image stabilization, and this is where the 5-axis in-body image stabilization (SteadyShot INSIDE) of Sony A9, A7 Mark III series, A7 Mark II series and A6500 comes in as a much-needed complement.

The heritage lives on, with the very same Carl Zeiss lenses from the dawn of full-frame digital photography now leveraging the latest and greatest mirrorless camera features and poised to benefit from further technological advances in the future.
