Z bayonet

from Wikipedia, the free encyclopedia
Nikon Z 7 with Z bayonet

The Z-bayonet is a lens mount system from the Japanese manufacturer Nikon . It was introduced in summer 2018 together with the Z 6 and Z 7 camera housings and is used to connect lenses to mirrorless system camera housings in the Nikon Z digital camera system .

technology

The Z bayonet has a comparatively large diameter of 55 millimeters and a flange focal length of just 16 millimeters. This means that image sensors in small format can be illuminated without unfavorably flat angles of incidence arising in the edge areas. Therefore, compared to the old reflex systems, it is technically easier to construct lenses with good properties and a large aperture and to avoid disruptive effects such as shadowing in the corners of the image ( vignetting ). Due to the smaller back focus, short focal lengths are possible without the need for a retrofocus construction . On the camera side, complex sensor shift mechanisms can be integrated without the camera housing becoming excessively thick.

Eleven electrical contacts are used to transfer data to and from the camera housing, one more than with the F bayonet.

Nikkor lenses equipped with the Z bayonet are electronically controlled and have no aperture ring. Focusing is done by a motor in the lens; there is therefore no mechanical transmission from camera to lens either.

As usual with Nikon, the bayonet is closed with a left turn and opened with a right turn.

Lens adapter

There are various lens adapters for the Z bayonet that enable lenses for other bayonet systems to be connected to cameras with the Z bayonet. The adapters compensate for the shorter flange focal length and the bayonet diameter.

Nikon bayonet adapter FTZ (camera side with Z bayonet)
  • Nikon F bayonet : At the same time as the presentation of the two camera bodies Z 6 and Z 7, Nikon presented the FTZ adapter for lenses with F bayonet . FTZ stands for f mount t o z mount .
  • Sony E-bayonet : Since 2019, the Chinese manufacturer Techart has been offering the TZE-01 adapter with which E-bayonet lenses can be connected to the Nikon Z 6 and Z 7. The adapter is only 2 millimeters high. It bridges the distance between the 16 mm flange focal length of the Z bayonet and the 18 mm flange focal length of the E bayonet. The adapter does not work on the Nikon Z 50.
  • Canon EF bayonet : An adapter with the designation TZC-01 presented by Techart in 2020 allows the connection of lenses with EF bayonet to the Z bayonet connection of the Nikon Z 6 and Z 7. A comparable adapter is offered by Fringer Tech Studio .

Basically, lens adapters can be designed for all bayonets that use a flange focal length of more than 16 millimeters. It is also technically possible to adapt lenses that are intended for cameras with a larger sensor.

reception

Nikon stuck to the F bayonet, which was introduced in 1959, for a long time, added it again and again and is considered to be a more traditional supplier in the market. The Z-bayonet was only introduced after other manufacturers brought mirrorless cameras onto the market, and it attracted a great deal of interest in the trade press.
