You have decided on the Nikon Z mirrorless system, but would like to use your existing lenses? This is possible.
With this adapter you can combine your M42 lenses with the Nikon Z series camera body. It should be noted with this combination that there is no transfer of autofocus control or aperture control. The subject must therefore be focused manually. Exposure control is with working aperture metering (i.e. the aperture currently set on the lens) in manual setting 'M' or with aperture priority.
