What looks like a release that prepares the camera for the upcoming Panasonic lenses, has a very pleasant surprise at the bottom of the list:

Quote

In some cases the VARIO-ELMARIT-SL 24-90 f/2.8-4 ASPH. did show front focus issues. Lens Firmware 1.1 does solve this issue.

 
What I experienced as "some cases" was very specifically that while using AF-S, the 24-90 lens would always front focus. A tiny bit (maybe one encoder position off), but nevertheless very very visible at 90 mm and wide open. After having ruined a number of shots that would otherwise have been keepers, and diagnosing the problem as related to AF-S, I completely switched to AF-C.
 
The good news is: I tested it today and it is really fixed!

I saw that as well, but there must be something else involved than just AFS. It's not something I've noticed - I use AFs all the time, and generally shoot at the wide end of the aperture range, where it would be noticeable. Do you use spot, zone, multifield or face recognition?

I normally use face recognition, awb, and auto iso, but I tried all permutations of those settings (and more) and only AFS triggered the bug. So apparently it is still something else.

It can also be related with small hardware differences, e.g. a different type of encoder for the af drive in the lens. That would explain the varying occurrence and the debates about it in internet fora.

Pity 3.4 then introduced a bug where Auto ISO is now erratic with the Leica R to L adapter =/

Maybe cunning plan to force users to ditch R classic and buy Sigma and Panasonic L mount lenses, or just usual cock up 👹

Maybe I will just stick to version 3.3 and buy Z7 with kit zoom plus Novoflex M-Z adapter 😘

AZN, could you explain better exactly what the bug is before I install 3.4?  I use a lot of my R lenses with the SL and the Leica R-Adapter L.

I made a note about this in another thread a week ago.

What happens with v3.4 is that the shutter speed and ISO defaults to the highest ISO rating you set for your auto ISO range.  So if you set 200-3200, Auto ISO will set the shutter speed to 1/3200 and the ISO to 3200 for almost everything except for very bright sunshine.  

In v3.4 the R lens identity is also not recorded in EXIF, even if the lens is recognised by the ROM contacts.  When you image review in the camera it will always show "0mm" for the lens focal length. This always happens even if you manually enter the lens identity via the menus.

Luckily it only happens when you use the Leica R to L adapter.  I found I could side step the bug by stacking a Leica  M to L adapter with a Leica R to M adapter.  Auto ISO and EXIF recording behave themselves now.  Of course you lose the ability to record R Zoom actual focal lengths and you have to manually enter R lens identities whenever you change lenses, but it's a good enough workaround.

Never had this problem with firmware v3.2 or v3.3.  Guess Leica never got around to testing firmware v3.4 with R lenses and their own R to L adapter =/

I am also using v3.4 on the SL with R-Adapter L and R-lenses with ROM contacts. I do not experience this problem. The Auto ISO works as in previous firmware versions, the focal length is correctly recorded in EXIF, and shown correctly in the image review in the camera.

I do not experience this problem

See Post #37 at 

 

Scott K had the same problem until he mounted a 75mm L lens, in which case the problem (somehow) corrected itself.

Just tried it again with my SL.  Yep, erratic behaviour for all my R ROM lenses (I have 8 fixed focal length and 1 zoom).  I don't have any L lenses to try Scott's fix.

YMMV.

In fact, I also mounted a L lens (24-90 to update its firmware) before testing the R lenses with R-Adapter L. Therefore, all observations seem to be consistent. - Matti

Has anybody found more information about this issue, which I describe below as a reminder?

As of firmware version 3.4, the focal length of an R-mount ROM lens mounted on the SL with the R-Adapter L is not communicated to the body. This creates problem with Auto ISO and especially with zoom lenses it is annoying that the EXIF data do not contain 0 mm instead of the actual focal length.

I have noticed that this problem can be reliably caused when an M lens is mounted with the M-Adapter L, unmounted, and an R ROM lens with R-Adapter L is mounted. The situation is cured by mounting any autofocus SL lens. The problem is not unique to my SL body because I can demonstrate on another body at the store consistently and reliably.

Hello Matti,

I've just taken quite a number of photographs using a 100mm macro with a Leica  R-L adapter mounted after a 24-90 autofocus lens.  It's the first time I've used it since updating the firmware several weeks ago.  In the camera data in Lightroom it is listing the focal length as 99mm and the lens model correctly. Here is a screen shot of the relevant part.  I need to follow your sequence to try it though...

I have never had trouble with the R ROM lenses mounted after the 24-90 either. The M-adapter seems to cause the trouble, which is reset by mounting the 24-90. It will be interesting to hear whether you find the same. If not, my M adapter may have a problem.

To follow up my earlier remarks about problems with the R-to-L-adapter after the 3.4 firmware upgrade...

A couple of weeks ago I went to the Leica Store in Sydney and had a chance to mount an L-lens and thus try Scott K's fix.

Well it worked, but only for a few hours.  I changed adapters later that day to use the M-to-L-adapter (which works fine with v3.4) and when I remounted the R-to-L-adapter the next day the bug was back.

So it appears the only way to fix the erratic behaviour AFAIK is to always mount an L-lens before mounting the R-to-L-adapter.  Bug.

So for now, the way I work around it is by using stacked R-to-M + M-to-L adapters.  No erratic behaviour, AUTO ISO works fine, EXIF data is recorded correctly.  Of course you have to manually ID each R lens when you mount it, but it will do until firmware v3.5 comes around...

Your experience seems to be exactly the same as mine. This is a good indication of the bug being easily reproducible. It seems that the problem is perhaps not the R-Adapter L but rather the M-adapter L. When I visited Leica Store Boston the promised to bring the bug and the way to provoke it to the attention of Leica, let's hope they will fix it sooner rather than later. 

The caveat of using the stacked adapters is that the used focal length of a zoom R lens is not going to be correctly transmitted to the body because the R-adapter M has no way of reading the focal length from the lens.

Agreed.  Everything else works as normal though.

Did some experiments and found you can still workably use the R-to-L adapter with Auto ISO.  You just have to disable the "1/f" option for the lowest shutter speed.  Of course the EXIF info is still missing/ messed-up, but it works.  Adding the lens ID manually doesn't work.

I installed the newly released SL FW version 3.5 and this annoying bug seems to have been fixed. The M-Adapter L does not cause the R-Adapter L to act up and mounting an L lens is not any more necessary as a fix. This is based on a short experience with FW 3.5.

Thanks for this and are downloading FW 3.5 as I write.  Will be interesting to see if they have indeed fixed the R-adapter-L bug.
