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:

Prettiest dress for my sweet little Q3!

Light and slim but sturdy. I love the hysteresis where it all comes back to place tight and neat after popping it out to change my battery. Unassuming and discrete but so elegant! Thank you Henley!

6-Bit Encoder Kit (for Leica M Mount Lenses)

Great Product!!

This is a NO BRAINIER MUSH HAVE if you have non coded lens. Works great and easy to use.

good!

I ordered from Japan, but a different product arrived by mistake. When I contacted the company, they responded immediately and even provided additional service as compensation. The product itself is exactly as I imagined—excellent quality—but what impressed me most was their outstanding customer service. I look forward to purchasing more items from them in the future.

Leica M11 · Slim Skin Case

Facilité

Très facile de mise en place des codes.

Lamotte

It's a really good product.

I had already purchased the X-E5 skin and loved it. Since I had an X100VI, it seemed sensible to also get one for that camera. So, I did.

The improvements over the bare camera are immense. It provides protection; the grip, especially the thumb grip, make it really easy to hold; it's really light - adds nothing to the weight (unlike the Smallrig one) and it takes about 2 seconds to whip it off to get to the battery compartment.

It's well worth it.

FUJIFILM X100VI · Slim Skin Case

FUJIFILM X-E5 · Slim Skin Case

The FUJIFILM X-E5 Slim Skin Case fits perfectly on the camera, almost like a custom glove. It noticeably improves handling, giving a more secure and comfortable grip during shooting sessions. The added layer of protection is an appreciated bonus without adding bulk. A smart accessory that complements the X-E5 beautifully.

Easy to use and well made

The template is easy to use and very accurately made. My M11-p recognized all 5 lenses I've coded without issues.

It was an excellent shop.

I made a mistake with my order this time, but the manufacturer handled it professionally and even offered a special suggestion for the order, which I really appreciate.
The products are also consistently reliable, so I plan to place orders regularly from now on.

The cover fits like a glove.

The first case I bought was for the Leica M3. I was completely won over by it and immediately ordered two more for my M10 and M6. It fits perfectly, provides additional protection and is easy to remove. Great workmanship, stays in place without any additional aids.
