Leica M Mount 6-Bit Encoder. The coder clips on to un-encoded lenses and allows quick and easy coding of any M mount lens.

Once the lens is encoded, your Leica camera will know which focal length lens it has mounted and record that information in to your photos (meta data) which will then be displayed in Lightroom and any other software allowing you to filter your photos by lens and focal length.

Your Leica will also apply various adjustments including vignetting, chromatic aberration and barrel distortion for cleaner JPG images and less post processing for RAW files.

Any other manufacturer lenses can also be coded to the closest Leica equivalent, generally improving the quality of your photos through the automatic corrections applied and the recording of meta data for lens length (28mm, 50mm etc).

For coding third party lenses, some experimentation may be required to find the closest and best match. We are actively working on a website to collect data from customers and the Leica community which will be launched in the coming weeks (around July 2024).

If you have a lens not listed in the table below, mounting your camera on a tripod and photographing a scene uncoded, then photographing the same scene with a few of the closest codes will allow you to compare and choose the best one for your particular setup. This should only take around 20 minutes for more than one lens due to it only taking around 20 seconds or so to clean a previous code off a lens and then re-coding it.

If you purchase the full kit, white and black pens are included along with the 6-bit coder, instructions and table of lenses and what to code them to. These pens are fully compatible with the Leica 6-bit sensor.

If you purchase the encoder on its own (instruction are also included) you will need at least a compatible black marker, many black markers do not work with the Leica 6-bit sensor. The recommend pen for use is the Black Uni-ball Super Ink Marker Pen 0.9. A white pen is usually not required but can help with successful coding for the M8 and M240.

A few lenses can have a screw where a 1-bit should be, filling this in with white allows you to then either leave it as white or place a black mark on top of it for successful coding.

Thanks also goes out to many others in the Leica community who are providing valuable information that allow us all to code our lenses effectively.

Excellent

Worked great on my 6 lenses

Recommend, but with one flaw.

Firstly, the first order I made didn't arrive because of some trouble with my DHL person. So I contacted Akara-Labs, and they sent a second unit to me right away. They knew of the problems with the German postal service. When it arrived, it worked perfectly, and I coded my lenses all at once. It was nice that the package contained a list with the corresponding Leica and Voigtländer or Zeiss lenses.
The one flaw I might have discovered for me is, that now that I have coded my lenses, the tool is mostly useless. I mean, I probably need to do it again in the future, but for now, it's just collecting dust on my desk.

But it's a well-made tool, and I would recommend it to everyone who wants to use its third-party lenses without having to change the lenses in the camera all the time.

Great template, I'm glad to have purchased it.

Perfect Tool for generation of 6-bit lens codes

This is a perfect tool for placing codes on old and non-Leica lenses. The work is done in minutes for a few lenses. All codes have been recognized correctly. Unfortunately, thanks to Brexit, customs fees have to be paid additionally on delivery in EU (Germany).

I DID NOT RECEIVE MY ORDER

after nearly 2 months, i did not receive my order and seller won't reply my email.

Please proceed refund or check delivery status and feedback to me asap.

this is unacceptable.

Hi Hung,

Your last email to us was 2 hours ago asking for delivery status/refund, previous to this we sent you an email on the 3rd September. We do try to get back to people as quickly as possible but sometimes it can take a few hours, our apologies.

As communicated just now via email, delivery was attempted by your postal service three times (twice in September and the last was on the 16th Oct), they say they have left a note to let you know how to organise delivery with them. If you are not able to organise this with them and the tracking info updates to say it's being returned to us, we will refund you and take the hit on the postage.
