[4.15 x 4 x 2.1"] This adapter does the job perfectly. Really well made and the tripod attachment is a nice bonus.

Offers great value for money over the other options - especially the Leica one.

[Leica L] Worth every penny. Solid fit. Works smoothly with the Voigtlander 35mm M mount.
I use it with my Leica CL
Plus the combined price( lens plus adapter) will not cause you to skip a mortgage payment if intent on owning a Leica 35mm, new or used.

Only wish it came with caps for both ends.

[0.44 lb] I recently invested in a wonderful Leica M10 plus 50mm f/2 Summicron. I also have a healthy assortment of Pentax lenses for my K1 and K5iis. My new Novoflex adapter works perfectly, and allows me to use my zooms and longer telephotos that Leica doesn't supply. That said, I am saving up to add more Leica lenses. Novoflex has lived up to the great reviews.

[0.44 lb] This is an expensive adapter but it works perfectly. Tight fit with no play whatsoever. Im using it with a lumix s5ii with zero issues.

[Leica L] Works super snug on S1H. no play from lens to adapter or adapter to bod.

[4.15 x 4 x 2.1"] I've accumulated quite a few M lenses over the years as I started with an M3 years ago. I now have an M(240) which is a terrific camera but I don't use it as much as I'd like because I find the rangefinder a bit difficult to use sometimes. So I've recently purchased an SL2-S, which I really like especially when using long lenses.

This adapter allows me to use my M lenses on the SL2-S. Leica must have designed the SL2-S sensor with the M lenses in mind, because the results are stunning. Focus peaking in the SL2-S works great with my M lenses, so manual focusing is easy and straightforward.

The adapter is expensive but beautifully made. I'm happy I bought it.

[Leica L] My 4th adapter from Metabones and they all work great

[Leica L] It’s a great adapter. Other reviews say it fits tight and I can say it does fit tight. Not to the point where I’d be afraid of breaking anything. It should loosen some over time. I like being able to use M mount lenses on my SL2S. I do not have any 6 bit coded lenses to say how well the contacts work but hopefully when Leica releases the new 35 summicron I can splurge some more. I give it an A plus. Great fit and finish.

[Leica L] This Leica M-Adapter L in silver arrived on time, intact, and as
described. It is a handsome addition to my Silver Leica SL-2;
and compliments various lenses which are similarly chrome
plated. The Leica M-Adapter L fits perfectly, and maintains the
Leica Brand continuity among associated components.

[0.44 lb] There are a few different options for M to L adapters, the TT artisans mount being the cheapest of the lot, and the Leica mount being absurdly expensive. This metabones option was right in the middle. It is built like a brick, I get no play from body or lens, and the full metal build can confidently hold anything you throw at it. I paired it with the TT artisans 50 1.4 for a great outcome.
