Ah, thank you! So it's just a hassle and the question, if I find something with the correct focal length 🙂

yes from M or R set. it is very useful even when using cinema glass with PL month 

you can select a list of favorites, so that you only see what you use.

you can ever create profiles for shooting with a specific lens and just select the profile.

Wow, that is well hidden! Thank you!

you can read the previews post for more information.

When you select a lens from the list, NO correction get applied. unless you are using coded lenses and Leica adapter. 

Only IBIS is activated

Not true on the SL cameras. When using a dumb adapter and non-Leica lens, it still applies color edge shift correction (if present in the profile) and minor vignette correction when you select a profile — these two corrections are baked into the DNGs with no way to strip them out. This is why it’s important to test several profiles with your non-Leica adapted lens to see which is best. The CV 50 APO for example benefits greatly on the SL2-S from the Leica 50 APO profile due to similar edge color shift between these lenses when used on the SL2-S sensor.

The M system does not bake profile corrections into the DNGs.

Not in my experience, and the conversation with the Leica people supported it.

I literally tested side-by-side shots with the CV 50 APO – profile "OFF" versus the Leica 50 APO profile. At f/2, the DNG results were obvious. With the profile off, there was significant vignetting, as that is a characteristic of that lens wide open. Same scene at f/2 with using the Leica profile, the DNG shows significantly less vignetting. The vignette correction was baked into the DNG because it could not be removed in Capture One by changing the lens profile, as can be done with typical lens corrections that are coded into a DNG for LR/C1 to read and apply, but are not baked in. I'm not the only one to have tested and confirmed this behavior. I didn't believe it either when I was told this was the case, but I tested it and confirmed.

Resurrecting this to see if anyone has gotten this to work with the S adapter L and the V adapter? Wanted to use the 110mm f2 for a bit but cannot find a way to activate stabilization. It is greyed out…

I agree it would be really nice if they just allowed you to enter in the focal length like Panasonic does. Why is it so needlessly complicated? It should just be applied automatically, chosen from a list or entered manually.

I think that Leica or the Leica marketing department decided to boost sales of their own very expensive adapters by leaving out functionality for those that do not want to spend this much on a adapter. In stead of just leaving out functionality that is not possible without read out of the 6-bit code (M-L adapter) or ROM contacts (R-L) adapter they wanted to make an extra difference with third party adapters.

As a software developer, the most straightforward way to deal with a "dumb" mechanical adapter would be to present the user with a list or fall back on the last chosen non code lens. From then on the Lens profile is known and the camera could work exactly the same as with the Leica native adapters. Job done...
Now, I am sure their software department spent a lot of time and effort to build in a handicap for third party adapters, making the firmware act different depending on the kind of adapter used. e.g. simply saving the chosen/read out lens profile in EXIF is disabled when using a non native adapter. And they did a bad job at making the experience consistent. 

IMO, trying to protect sales by making your product perform worse when used with products from competitors is almost always a bad decision, and will backfire on the brands reputation. For 99% of their products Leica do not need anything other than their build quality and excellent performance to justify their price point.

i use the leica M adapter T, and have stab available for all M lenses

for my R lenses, i simply choose the closest M lens

same for the dozen  or so vintage M42 and other really vintage LTM lenses

For R lenses, only the M lens profiels are presented when you use native M-T or M-L adapter with a R-M on top.
You can bring up the R lens profiles by:

1. Code your R-M adapter. Then only the R lens profiles are presented.
2. Use a third party M-L adapter and then put your R-M adapter on top  brings up M and R profiles
3. Use a third party R-L adapter to bring up M and R profiles
4. Use a native Leica R-L adapter, brings up R lens profiles only

Just to nuance a bit. With my Urth R-L adapter when I choose the 50mm R lens in the list on my SL2-s firmware 6.0 it is written in the exif data.

f stop is an educated guess....

yes im aware of that

Well, congratulations to the Leica software team for finding a way to make buying two of their very expensive adapters and using them as intended a more expensive and worse experience than buying an entire Panasonic S5ii and cheap ebay adapter.

Thanks for getting my hopes up.

Unfortunately, it turns out that after updating my Leica SL (601) to the latest firmware (v4.1) it still shows "Lens NA" in the EXIF after choosing the M lens profile with my Novoflex M-L adapter. So it seems this only applies to SL2 and up.

Maybe you were using a Leica native M-L adapter with a stacked third party R-M adapter that is coded as adapter when you did this test?

No, it was an Urth R to L adapter.

Hi,

on my Nikon Z I can manually enter the focal length of the adapted lens, so that the image stabilization knows what lens it is working with.

However, in the SL2-s I cannot do this, am I missing something? How can the image stabilizer operate properly if it does not know the focal length of the lens mounted?

 

Thank you

 

Under lens profiles, select the last option, "Other lens."  It will then display various focal length options.

This works on both my SL2 and SL2-S, both of which are on FW 6.00.

The option shows when using my Novoflex LET/LER, a dumb adapter, with any R-mount lens; and with any non-ROM R lens using the Leica R-Adapter-L (16076).  

The selected focal length is displayed in EXIF along with the name "Unknown lens."
