Techart Unveils First-Ever Contax G to Nikon Z Autofocus Adapter

Techart has announced its new TZG-01 adapter, the first-ever Contax G-mount to Nikon Z-mount autofocus lens adapter with full support for continuous autofocus modes, eye-detection, and in-body image stabilization. Now, Nikon Z owners can pick up the highly-regarded Contax G-mount lenses designed for Contax’s G1 and G2 rangefinders in the mid-90s.

Contax G series lenses were launched in 1994 to support the company’s G1 and G2 rangefinder cameras. According to Techart, each of the lenses are light and portable with classic optical designs and autofocus functions.

This new TZG-01 adapter is based around the same design Techart used for its TA-GA3 Contax G-mount to Sony E-mount autofocus adapter it released back in 2014. This new adapter for Nikon mirrorless cameras uses a motor to drive the screw on G-mount lenses that initiate the focusing mechanism. Through it, AF-S and AF-C are supported as shooting modes as well as manual focus.

“The Techart TZG-01 simulates the autofocus mechanism done by Contax G cameras to their lenses. The brushless motor will drive the screw on G lenses which control the movement of glasses to achieve focus,” Techart explains. “There is a dial on the side that also allows users to manually adjust the focal point by hand. It is for minor adjustment of the focus point in autofocus mode and realization of manual focus as users may prefer in certain situations.”

The TZG-01 adapter is constructed of aluminum and copper alloy and features a new 32-bit ARM CPU for transmitting autofocus and metadata information. The adapter includes internal flocking to minimize light penetration.

An AF motor built into the adapter will drive the screw AF system on the Carl Zeiss G-mount lenses and works in both AF-S and AF-C shooting modes, in addition to manual focus, which is controlled using a small dial on the side of the adapter. Techart says the adapter fully supports in-body image stabilization (IBIS) as well as all of the AF modes, including dynamic area AF, auto-area AF, and single-point AF. All of these functions should work while shooting video as well.

The Techart TZG-01 Contax G to Nikon Z autofocus adapter is available from Techart for $299.
