I just grabbed a Leica SL2 and I am really excited to start using my M-mount lenses on it. I have been looking at the official Leica M-Adapter L, but the price is pretty steep for what it is. I am curious if third-party options like Novoflex or even the Voigtlander versions are worth considering for a professional L-mount setup.
I am specifically looking for something with a solid build that won't have any light leaks or mount wobble. Also, does any third-party adapter actually support 6-bit coding for lens metadata? I would love to hear your experiences with different brands before I pull the trigger. Which adapter do you think provides the best performance for the money?

Check out the Novoflex M-Mount to L-Mount Adapter. I once had a cheap one jam. Now I only trust Novoflex. Note: third-party brands dont support 6-bit coding like the Leica M-Adapter L does. gl

> third-party brands dont support 6-bit coding This^ also check the Voigtlander VM-L Mount Adapter. Its definately super solid, but third-parties dont have the proprietary optical sensor for 6-bit reading like the Leica M-Adapter L. Basically a patent issue.

i feel u on the price thing... i actually started with a cheap brand and it was a total nightmare with light leaks... just a mess lol. if you want that pro build without the leica tax, honestly the novoflex is REALLY solid. just be careful cuz third-party ones wont read your 6-bit codes. lesson learned: pay for official if you need data. TL;DR: novoflex for build, but only leica reads codes.

Like someone mentioned, that 6-bit coding stuff is basically a patent trap and it is honestly so frustrating to deal with when you just want your gear to work. I have spent way too much time worrying about this and it just feels like we are being punished for wanting to use M glass on a modern body.
- Be careful with the super cheap options like the K&F Concept Leica M to L Mount Adapter because the mount wobble is a real thing and it will drive you crazy.
- I would suggest you stay wary of the Urth M to L Lens Mount Adapter too... I have heard of people getting light leaks which is just a nightmare for long exposures.
- It is just a total mess that we are forced to pay such a huge premium just for some metadata and a solid fit.
- Honestly, the fact that there are no reliable mid-range options that actually support the coding is just a joke.
- Make sure to check any budget buy for metal shavings because that is the last thing you want near your SL2 sensor... it is just so stressful trying to save money on this stuff.
