The adapter reduces the focal length of the lens by 0.726x and have 1-stop increase over the lens’s aperture range on an APS-C cameras.
Enlarge Aperture Range and Reduce Focal Length
Zhongyi Lens Turbo adapter is an adapter with optical elements inside. It is a focal length reducer, allowing camera bodies with smaller sensors to make use of the full image circle of lenses which was designed for full-frame sensors. The action of taking the full image circle of a lens will significantly increase the light entering the sensor.
Currently, the crop factor of Nikon Z APS-C cameras is 1.52x, the crop factor will be offset when working with the Zhongyi lens turbo adapters. For instance, a 15mm full-frame lens will have an angle of view of a 22.8mm lens (full-frame equivalent) while being used on APS-C camera. Whilst with the use of Lens Turbo adapter, the angle of view will be reduced to 16.5mm. The angle of view will therefore be similar to using the lens on a full-frame camera body.
The new Lens turbo for Nikon Z cameras is thus perfect for Z50 and ZF-C users who are looking to use full-frame lenses.
Premium Built Quality
The adapter barrel is built by nicely coated metal. 4 elements with the metal body weigh only 233g. Compared to the same generation of Lens Turbo adapters in other mounts, the lens release tab has improved from a small knob on the side to a horizontally down-pressing tab. It is easier to grip, at the same time, gives a more robust feeling. There is no electronic contact on the adapter.
Aperture Ring For Nikon Lenses
Nikon G lenses were designed to be electronically controlled by the camera, therefore there are no aperture rings on the lens bodies. Despite the lack of electronics contact, ZhongYi provides a solution with an aperture control ring built into the adapter. Users can still adjust the aperture by using the ring on the adapter body.
Preservation of Image Quality
ZhongYi Lens Turbo Mark II has a refined optical structure with 4 elements including One Extra-Low Dispersion element to reserve the image quality offered from the original lens. Performance over edges or corners of the images is closed to native lenses. Users do not have to compromise image quality after adaptation.
Cannot be used on Nikon Z mount full frame camera.
Electronic functions of AF / AF-S lenses such as electronic focusing and aperture control are disabled.
