Megadap unveiled the world’s first autofocus adapter for Leica M manual lenses on Nikon Z cameras

Press text:

Hong Kong, 29 Oct 2020 – Megadap, a new manufacturer of electronic adapters, has unveiled the new Megadap Leica M – Nikon Z Autofocus Adapter. It is the World’s First adapter to be used on Nikon Z cameras which can turn manual focus lenses into autofocus.

The new Megadap adapter replaces the focusing mechanism of the lens by incorporating a extendable bayonet structure. The adapter is built with electronic contacts to communicate with the Nikon Z cameras and utilizes the camera phase-detection autofocus algorithm to determine the focus spot. The motor in the adapter will then drive the bayonet to extend or retract. The distance between the lens and the camera sensor will hereby be adjusted until the focus is reached.
The focusing experience of Megadap is fast and precise. It currently supports Single shot AF (AF-S), Continuous AF (AF-C) and servo AF (AF-F) mode. For AF-area, Single-point AF, Wide-area AF (S/L) and Auto-area AF can all be used. It is compatible with Nikon Z6, Z7, Z50, Z6 (ii) and Z7 (ii).

Unlike similar products being made for other camera systems, the new Megadap adapter is built with a new patented circular extension structure so that it is able to support heavier lenses and eradicate any potential wobbling bayonet issues after prolonged use. It also incorporates a much longer extension (maximum 6.5mm bayonet extension). This is longer than the focus throw of most manual lenses in the market and is gives the lens a much wider focusing range. A micro USB port is equipped for future firmware updates.
In addition to the Leica M-mount lenses, users can also stack additional adapters to turn lenses with other mounts (E.g. EF, F, FD, PK, MD, OM, M42, LR, CY, etc) into autofocus. Owners of legacy manual lenses will now have an entirely new experience with the modern autofocus technology.
More product information and focusing videos can be found from Megadap official website (http://www.megadap.net/)

Pricing
The suggested retail price of Megadap Leica M – Nikon Z autofocus adapter is $349/pc and it can currently be purchased via their official webstore (https://megadap.net/product/mtz11/). 2 years warranty and Fedex international shipping is provided for all direct purchase from the store.

Nikon says that adding autofocus on their 58mm f/0,95 Z would have increased the size of the lens “beyond imagination”

In an interview released at Xitek Nikon said that they actually hoped to implement autofocus on their 58mm f/0,95 Z-mount lens. But the autofocus was slow and lens size increase “beyond imagination” 🙂

Here is the google translated text:

Of course we have also studied AF, and driving the focus lens itself can be done. But the action is quite slow, not as fast as manual operation. At the same time, the increase in size is far beyond imagination. It cannot be driven by the existing ultrasonic motor, and a larger actuator must be arranged outside the lens.
Therefore, if you really want to achieve AF in the F0.95 lens, this optical type will not work. You need to reduce the focus lens and use the internal focusing method. But using this method will result in a longer overall length, which means that peripheral components will also increase, and the lens will still be larger and heavier than it is now. Even if such a lens is made, even if the product is very special, it may not be established as a product, so we gave up AF.
