Monster Adapter announced the LA-NE1 adapter, which supports autofocus, aperture control and data transmission between Contax N-Mount lenses or Sony E-Mount camera systems.

Contax N-Mount

Although the Contax N and N Mount cameras were very short-lived they did produce nine lenses for it by Carl Zeiss. The Contax N cameras consisted of two film SLRs and the N digital.

Contax N, a Japanese DSLR camera that was released in 2002, was created by Contax Japan. It took two years for the six-megapixel camera to be released. The public and press didn’t like it so it was taken off the market in less than a year. It was the first full frame DSLR, and it actually beat Canon’s EOS-1Ds that were released later in the year.

While there weren’t many Contax N-mount lens options, they aren’t common on secondhand markets.

The LA-NE1 Contax N-Sony E Adapter

The adapter supports data transmission between the lens (and the camera), which includes aperture control and autofocus for all nine N-Mount lenses. The adapter also supports an aperture ring if the lens has one.

Monster Adapter is so confident in the LA-NE1’s ability to provide N-Mount lens with eye-AF (on people and animals), as well as high-speed, focus-tracking shooting. Contax lenses can also be used with the Sony’s in-body imaging stabilization.

The adapter includes a tripod mount that can be detached for heavier optics. It also features a dust-proof rubber band on the E-mount side bayonet, which is claimed to reduce water and dust intrusion.
