Leica M Mount 6-Bit Encoder kit (includes pens, encoder, instructions and table of codes). The coder clips on to un-encoded lenses and allows quick and easy coding of any (not limited to) M/LM, ZM and VM mount lens. 

Once the lens is encoded, your Leica M and SL2/SL3 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.

An added benefit for SL2 and SL3 users when used with the Leica M adapter, is setting the correct image stabilisation for the lens length.

Any other manufacturer lens can 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 but all M mount lenses can be coded.

The kit includes a compatible white and black pen, along with the 6-bit coder, instructions, and table of lenses and what to code them to. 

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.

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.

Note: The QR code on the encoder takes you to the instructions online which includes the table of lens codes. If you are out and about with the encoder and pen in your bag, this should hopefully help code your lens quickly.

For SL2 and SL3 users you will also get the benefit of correct stabilisation automatically. An excellent video by Jonathan Harris at Worldwide Camera Exchange explains in more detail here:


Matt Osbourne, a professional model photographer reviewed version 1 of our encoder. See what he thought about it here:

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.

Great product for third party Leica mount

Highly recommended for those photographers using Voiglander m-mount lens on Leica bodies. Eliminates the need to remember to change lens profiles in body each time you swap focal lengths. But be aware on a Leica SL body you will need to use the Leica M adapter for the 6 bit coding to be read. After market adapters don’t offer that option. The product came shipped perfectly. Glue dots held down pens and device nicely preventing rattling around and possible damages. The product is extremely simple and completely overpriced. But it’s available no where else and I applaud their research and development of the product. I’m happy to support the small business vendors.
Highly recommended the product. It performs as advertised, and 3d printed in quality.

So far so good.

Works and is easy to set up.

An simple and excellent product

Making use of 3D printing this product is amazing. The chart of coding is also excellent. I was very happy to pay for a quality product and have managed to code my VM 50/1 and my Chinese replica 7 elements 35mm. Found out my Kobulux or Avelon 21/2.8 need a new LTM adapter to do such automatic coding.
Great seller. Excellent and prompt service. I hope to patronize more as new products become available

Clever idea, well executed.

This product is an excellent idea and well executed. Simple to use with good instructions it has been a great help for recording which lenses I'm using.

The coder worked great on all but one lens.I was able to get a close match for all Voigtlander that were not listed .Supplied with black and white pens and the template.Nice product..I liked getting a discount on the two M 1 body skins as well.
