It would be interesting to get a list of Panasonic lenses that don’t work with BBF and report this for a bug fix to Leica. I submitted one for the 16-35 and got a polite response from Leica that they would consider fixing it in a firmware update.Not holding my breath, but it might help if more people report the problem. No worries. I'm not sure this is so much a bug as a design flaw/decision depending on your POV. I could be wrong, but my assumption is that the clutch physically engages the focusing mechanism to the AF motors. If so, when you disengage the clutch there is no way for the AF to work. This should be easy to verify with any Panasonic L-body, so the question becomes does BBR work with any of the S1xs when MF is engaged? Link to post Share on other sites More sharing options...
Advertisement Posted September 30, 2021 Posted September 30, 2021 Hi Tailwagger, Take a look here Trade my Panasonic 24-70/2.8 with the Leica equivalent just for Back button focusing or other reasons?. I'm sure you'll find what you were looking for!
RBB Posted September 30, 2021 Share #22 Posted September 30, 2021 Sorry but I don't understand or don't want to understand or some lenses and camera's won't work together. Luckily I still have a Panasonic lens, the 24-105mm and have just tested it. The lens with the switch on the lens set to MF, the shutter button does not focus and the joystick does. Ridiculous isn't it?? Link to post Share on other sites More sharing options...
SrMi Posted September 30, 2021 Share #23 Posted September 30, 2021 With Panasonic lenses that use the clutch to enable MF, AF is entirely (mechanically?) disabled when the clutch is engaged. Therefore BBF cannot work when the clutch is engaged. However, with lenses that use MF/AF switch or the menu, AF is still possible (via joystick) when MF is selected. The solution would be for Leica to allow disabling AF via the shutter button in AF mode. Until then, I am avoiding Panasonic lenses with clutch.

For what it’s worth, I can get the joystick to initiate focus in AF mode, but focusing with the shutter button remains active, so not useful. Apologies if I added any confusion to this issue. I didn't realise that this was the case with the clutch operated lenses from Panasonic. Having been pretty sure that I had used BBF when I had the Pan 70-200 F/4 it must have been on a Panasonic body, I did have an S1 for a short time. It really should be possible to utilise BBF with all lenses sporting an L mount, it needs fixing. Just to confirm again though, Lumix lenses with switch not clutch, do work just fine.

The Panasonic 50mm 1.4 is the same, the back button works to focus but you can not disable the shutter from focusing, a simple firmware upgrade that allows the shutter to be disabled is needed. Every other camera manufacturer that I have used allows back button focus and disabling of the shutter button from autofocusing. Link to post Share on other sites More sharing options...

I think it’s a superb lens. I can’t compare it with either Sigma or Panasonic equivalents as I haven’t used them, but, I agree with the comment by Robb: use what you enjoy. And I love the results I’m getting from the Leica. It isn’t a lightweight lens but it suits the SL2-S. It’s a great buy. Just bought the same kit and I found it crazy expensive in any Land. I bought it anyway and may have to live off bread and jam for the rest of the year. The 24-70 seems beautifully built compared to the Sigma variant and I was surprised the weight ( something I usually dislike) didn't bother me as much as I expected. It just feels right and balances well on the camera. Getting ready to test the weatherproofing in winter conditions. Link to post Share on other sites More sharing options...

I hope you enjoy it as much as I do. 1 Link to post Share on other sites More sharing options...
bpLeica Posted October 3, 2021 Author Share #28 Posted October 3, 2021 It seems like many of us are caught into this dilemma and thanks for all the feedback… bottom line is that the focus clutch doesn’t allow for bbbf … there was a second inherent inquiry in my original post though… has anyone compared the two lenses and is the Leica truly better than the lumix lens… FYI my camera store advised me not to trade-in the lumix as it is practically no difference Link to post Share on other sites More sharing options...

Well, I did some more digging on this and although redundant of some other posts, I confirm that the "clutch" mechanism in the Pro S Panasonic lenses prohibit the back button focusing on the Leica SL cameras. What's more strange is that the stabilization is also an either/or situation... Panasonic 70-200 cannot do what the Leica 24-90 can in terms of combining IS.. if you activate it on the lens, the camera automatically stops IS and visa version... 1 Link to post Share on other sites More sharing options...
bpLeica Posted October 27, 2021 Author Share #30 Posted October 27, 2021 UPDATE FROM POSTER; I had occasion to spend a couple of days in Wetzlar and many hours with the Leica folks who are very helpful of course. I had never seen the 24-90 I physically and given the size and heft of my 50/1.4 I assumed it will be even heftier. Once I got to test it at the Leica HQ, and I mean spend two full days with it and the 24-70 side by side, here were my conclusions based on my use case. 1- it is heavier but the Panasonic 24-702.8 is bulkier! That was a surprise. 2- focusing was noticeably snappier especially in video mode. 3- big surprise out of left field was how the OIS affects video shooting hand held. For someone who knows what they are doin it nearly takes the gimbal out of the equation. I modified an S1H small rig to fit the ninja and a lag receiver and notice a huge difference. 4- frankly the picture quality between the three under ordinary use is not a game S thing shines under extreme circumstances and you can tell in those cases that this is not a normal lens… I kind of understand why Leica insisted on variable aperture to maintain the consistent iq ‘anyway they were very accommodating and traded in my pan 24-70 for a new 24-90… it fits with my customized Lowe pro case without a problem as long as I can figure out what to do with the cannon like hood… just sharing the new developments for those who care… 4 Link to post Share on other sites More sharing options...

It has “Certified by Leica” stamped on it, yet you can’t put it in MF mode on the SL2. Not a deal breaker with this particular lens but odd, Makes me wonder what “Certified” means. I’ll think twice before getting another Panasonic lenses. Can't you just slide the focus ring back and place it in MF? Mine does that, it even auto zooms for focus. What really bugs me is that focus tracking does not work in AF with Pana lenses. Edited October 29, 2021 by Andrew Gough Link to post Share on other sites More sharing options...

Andrew Gough Posted October 29, 2021 Share #34 Posted October 29, 2021 (edited) With leica Lenses, I usually have the camera in tracking as opposed to face/body tracking. This mode allows me to set the initial tracking point on a person or object, and as long as I keep AF active the camera will track the selected focus point/object in the frame. I find it to be very fast for focus recompose type shooting. It did not seem to work in my house on my SL2s, but once I took the polarizer off, it works. So please disregard my previous post. 😳 Edited October 29, 2021 by Andrew Gough Link to post Share on other sites More sharing options...
