An autofocus adapter for Leica M mount lenses on Nikon Z cameras is soon available.

It appears from the text on the box that the brand name is Gabale, but in the post where this is found, the adapter is called Techart MTZ11.

Gabale and Techart are obviously closely associated. On the official Techart website I have seen images of their products with credit to Gabale.

The images are obviously of early prototype models and was posted on a Japanese Nikon Facebook site on September 5th (2020):


... but when you check out the original poster, it's Shoten Kobo, which may indicate that the brand Shoten is also in the same group of companies:


Whether the autofocus adapter is designed and manufactured by Gabale, Techart or Shoten is perhaps not that important if it's the same group of engineers behind.

In a Chinese forum post the engineer(?) wrote the following on September 4th (here translated by Google) :

"Hello everyone, I’m Gabriel, I have kept you waiting.
After the release of the Nikon Z camera, we found that the Z mount has a huge advantage in adapting, especially when adapting to the rangefinder lens of the M mount, the effect is close to its performance in the original camera. The Nikon Z mount has many advantages, and I position it as the most suitable mount for adapters. The Nikon Z7 has also become my portable camera.
Last year, I discussed with several partners to make a MZ manual lens autofocus adapter ring. The project was officially approved in September, and it was originally planned to be launched this spring. The plan was disrupted by an epidemic. Logically, it is necessary to postpone the delayed time, but in fact many tasks have to be repeated.
Many friends keep asking me about my progress. I am very grateful to you. It also gave us pressure and motivation from the side. The process did have many twists and turns, but the result is good. Now the adapter has been officially developed successfully, and it has been tested for some time. This time, the mechanical structure is completely new, and the spiral transmission structure is used to solve some of the previous pain points.
This time the adapter has also registered a utility model patent last year and will use the new trademark "Megadap".
This time the adapter can be used for single-shot autofocus, and it can be used in both camera and video modes for focus tracking. Although there is a gap with the auto lens, it is a small improvement. I recorded a short video, thank you again for your expectations. The adapter left the market very quickly this time.

The video can be searched for "Gabriel mtz11" on Youku."


I put some of the most interesting new in bold. The Leica M to Sony E autofocus adapter has been criticized for being weak resulting in tilted focus plane after some use. This appears to be solved in the new adapter for Nikon Z.

In a post just after the above quote (on October 2nd) another user says that Gabriel has now confirmed that the adapter will be available in the middle of October. That's very soon!

The video mentioned in the quote is showing the adapter doing it's magic here, also shared by Shoten Kobo at Facebook:

 
Considering that Techart already released the E to Z adapter, it wasn't going to be long before they released this.

I have no problems at all with their adapter for Sony E, no 'droop' at all after more than a years usage.

On a side note, Fotodiox (which copied the Techart) has already released a LM to FX auto focus adapter, which I got only this afternoon.
 
I should perhaps correct myself regarding brand name since the developer himself says the brand name of the Leica M to Nikon Z autofocus adapter will be a new one: "Megadap".

I found a picture of a later prototype where it says Megadap on it, which indicates that it won't be a TechArt branded product after all.

Looks like the AF module from a Minolta SLR lens: circa 1985.

The main functional difference here is 2mm more focus adjustment range -- which is actually a big deal given it went from 4.5mm to 6.5mm. Basically, from an engineering perspective, there's a lot more space, not just the 2mm flange difference, but also the ability to have a wider diameter (larger clearance on Z mount for stuff around the lens).

In any case, much as I'm not crazy about Nikons, I have to agree that Z is the best mount right now for adapting manual lenses. E is second place... but still first place on adapting AF lenses, largely because in addition to EF/EF-S and F lenses, E is the only mount that makes Minolta AF lenses autofocus.

The interesting thing is that you could probably shave another 10mm off the flange distance once we've got all-electronic shuttering up to the task. I wonder if that will bring another round of new lens mounts?

Structural issues, from tele lenses to the handgrip, when a body becomes that flat? FF film rangefinder bodies did not become that flat either. For wide angles retrofocus designs were not thrown overboard in favor of symmetrical WA designs when mirrorless appeared. The gain of 10mm in the body replaced by 10mm added to each lens, I doubt that is going to happen. The Hasselblad XCD mount register distance versus its sensor format would deliver 14mm register distance in an FF version. The XCD lenses have the shutter integrated. In camera sensor tilt and shift a more likely feature appearing when the focal shutter can be abandoned and the space has to be filled. One wonders whether camera manufacturers can afford yet another mount in the next two decades.

Timing gears, the focal plane shutter, and thickness of the 135 cartridge prevented getting thinner. Those things are all gone. We also now have many materials that are plenty strong. There are still constraints for the EVF, etc., but cell phones have gotten insanely thin and once folks realize cameras (or at least camera backs) can be, I think it will have to happen.... Of course, a very shallow flange distance allows, but doesn't require, a thin body: it could still be a thick body with the "film plane" very close to the front.

Conventional sensors needed rays coming in perpendicular to the sensor plane -- so-called rear telecentricity -- partly because of depth of the wells that house front-side-illuminated pixels and partly because of the low fill factor needing microlenses. Well, most sensors are now BSI with high fill factors....

New cameras will be designed for new lenses, and there are lots of methods that could yield lenses with entirely different properties from what we are currently used to. I don't know how soon those new lens techs will be ready -- for example, I've been shocked at how slowly diffractive optics have been progressing (and I'm not talking about the type Canon just put in their two long telephoto lenses). However, lens construction definitely can profit a lot from nano fab processes, and that will happen sometime. That's when our collections of old lenses will really become quaint old antiques.
One wonders whether camera manufacturers can afford yet another mount in the next two decades.
Based on how cell phones have evolved, I don't think they'll have a choice.

For that matter, your cell phone could one day fairly soon have a medium-format camera in it... and there are advantages to that, because light doesn't scale down.

No; Minolta didn't have motors in their lenses when they introduced the Maxxum 7000 in 1985. The screw-drive system in the body was way smaller than this.

It might not be obvious, but this adapter is huge compared to the LM-EA7 -- literally several times the internal volume. Thus, it can fit a beefier drive system as well as getting 2mm more motion range. All because of the bigger, shorter, Z mount.
 
Did you order one? I'm really intrigued by the idea of using this with adapters to other lens mounts.
No, not yet. However, I have just read reports from a user on Facebook, and at first he said the focus wasn't that great at distances longer than 2 meters, but that was with the Zeiss Sonnar 50mm f/1.5 ZM which isn't that great wide open. When I asked him to test with his 35mm Biogon ZM, the results were much better - according to him.

So, I am still very interested, but I haven't ordered it yet.

What he told me regarding functionality, I can share here:

Setting focal length:

A list of how different focal lengths are stored in the adapter is provided on a piece of paper (Chinese only). While selecting f-stop values from f/6.3 and smaller, focal lengths from 10mm to 135mm can be stored in the adapter by taking a photo and then turning off the camera. When the camera is turned on again, the adapter will communicate the selected focal length to the camera and this will be stored in the EXIF data in the image files. And of course the IBIS will work based on the set focal length.

Setting (current or max) aperture:

This is limited to values from f/1.4 to f/5.6. No f/1.2 or f/0.95 setting available. I think setting of the aperture is done by simply turning the aperture wheel (the one on the front of the camera). If that is true, then turning the wheel will let us tell the camera what aperture is used up to f/5.6, not only the max aperture. From there, it (probably) gets messy.

EDIT: I have just ordered it from a seller on eBay. Since the item is in China and I am in Norway, it will take at least two weeks before I have it.

I just realized that there are TWO competing adapters on the market now.

Techart has made their own autofocus adapter for Nikon Z cameras too: Techart TMZ-01:

https://leicarumors.com/2020/10/24/...ras-with-the-new-techart-tzm-01-adapter.aspx/

After checking the short demo video, I feel confident I want to stick with the Gabale / Megadap MTZ11 adapter. While the Techart is smaller, it is quite noisy. The Megadap is much beefier, but almost silent in the demo video I linked to above.

The official shop in English is here (discovered after I bought it at eBay) :

Hi Lars. Can I share your post on the Nikon Z forum, in case some people are interested?

Quote from press release:

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

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.

Well, that claim is off because TechArt's LM-EA7 worked onNikon Z over a year ago... but it wasn't designed for Z directly, just adapted to it.
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.

Well, that's good if true.

Circular extension structure? Not a conventional helical? Interesting.... Personally, I just use screw threads and let the lens rotate....
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.
Of course.

Broken English, but basically sounds well done.
 
Nikon should be pleased the more lenses that can be adapted to the Z bodies then the more camera bodies they sell and the more camera bodies they sell the more oem Z lenses they will sell (eventually).

One might wish that Panasonic would get the same message for their L-Mount with the “afterthought-level” support for EF.

If it works at even a rudimentary level it's probably worth it.
 
Thanks Lars. Surprisingly there is no available information about this adapter in Hong Kong!
