I don't have the Newer adapter. With the Funmount adapter I don't see a need to tweak the text file on the field. You choose one of the 12 lenses that you pre-define by selecting an f-stop between f/10 and f/36 on the camera, and cycling power.


Can you share exactly how to configure the lensinfo text file to enable this? I have yet to find any reliable and accurate info online about how to do this.

If you use the default lens definitions, you do not need to change the file "lens.txt". To select a lens, select the corresponding aperture according to the table in the following link, then take a picture and turn the camera on and off.

https://www.icloud.com/iclouddrive/099L_rO-tQ1vArf_K9bCZo1dA#default_lens_selection_table

For example:
1. Set the camera's aperture to f/16 to select lens number 5, which by default is a 35mm f/2.
2. Take a picture of anything
3. Turn OFF the camera, then ON

Now the camera should indicate a 35mm f/2 lens. When imported into LR Classic, the EXIF indicates a Nikon 35/2 lens.

The table comes from the manual, which can be downloaded from the following link:

https://funmount.com/manual?_l=en

You can change the data on the file "lens.txt" to specify different lenses. The adapter attaches to the computer with a usb cable and shows off as an external drive with the file. You should use an ascii text editor to modify the file, and make sure you save the modified file and properly eject the drive.

I just got a TTArtisan 6-bit M-Z adapter running firmware 1.0.0. Is it worth updating to 1.0.2, or are there any known issues introduced with the newer version?

I updated it from v1.0.0 to v1.0.2 (which is the latest on their website), but the camera is now showing 2.0.2 instead. Not sure if anyone else is seeing that.

Either way, good news is that the original firmware didn't recognize the 6-bit coding on my Leica 28mm f/1.4 Lux, but after the update it reads it correctly now.

I just updated mine to 1.02 and now focus confirmation no longer works and I have NO idea why. Do you happen to still have the other firmware files? Haha

Did you use a Mac or a PC to update the firmware?

I used a Mac the first time I did the firmware update to 1.02 and the adaptor stopped working. Reapplied the update using a PC and it all came back to life.

I used a Mac, that’s all I have access to. Maybe that’s what did it then.

Edit: I downloaded a Windows VM and tried again and it worked. I guess you just have to use windows on it 🤷🏼‍♂️

I'm curious to hear what technology you used to run that VM... my technology stack for that was not pleasant to navigate (an old VirtualBox + windows ISO that were compatible with my aging Mac).

Haha well. My mid-2015 pro died a year ago, and I inherited my wifes 2016 pro when I bought her an M4 Air. So…also running a very old setup haha. I just downloaded Parallels and then windows 11. It was all a free trial which is all I needed! There won’t be any firmware updates to the 6bit clearly, so won’t need to use it again

Here's something interesting I ran into.

I updated my TTA M-Z 6-bit adapter firmware to the latest version from here: https://ttartisan.com/?other/M-Z-6Bit.html

It lists the latest as v1.0.2. I downloaded it and updated it using my son's PC and everything went smoothly with no issues.

But when I check the firmware version on my Nikon Zf, it shows v2.02 instead!

Has anyone else seen this mismatch?

On a positive note, the update did fix the issue I was having where my Leica 28mm f/1.4 Summilux was not being auto-detected properly.

Last night in my frantic Internet digging to figure out what happened to my adapter, I did see a few places where people said the firmware was showing up as 2.02. No indications as to why though 🤷🏼‍♂️

Thanks for the info.

Just out of curiosity, I connected the adapter to my Mac and it showed up in Finder under "TTARTISAN". Just like on the PC, I found a DeviceInformation.txt file on the drive, and it confirms the adapter is indeed running v1.02.

So the Nikon Zf is incorrectly reporting it as v2.02, but otherwise everything is working perfectly and the adapter is performing as expected.

Here is the content of the txt file:

DeviceInformation = MTZ Adapter Kedis
HardwareVersion = v1.0
BootloaderVersion = v1.0
SoftwareVersion = v1.02
SoftwareReleaseDate = 2024-02-20
