I had a S5 for a while though. I assume it's the same on the S1R, and there's no reason why it shouldn't be. Anyway, it's 100% the same autofocus. Where do you think Leica source its AF system? Leica engineers add minimal UI retouches and system compatibility, but the engine is 100% the same. When I tested the S5 and the SL2-s side by side, I couldn't find any significant difference. Maybe the S5 was a hair faster/more reactive, but in real life it had zero impact. 1 Link to post Share on other sites More sharing options...

In the end it's just a design decision. As you mention, other camera brands offer the full-info display that you want, so you have the luxury of choice. It's important to feel comfortable with our tools, no one will criticize you for choosing something that is more agreeable to you. Link to post Share on other sites More sharing options...

Because while the Panasonic Sx and the Leica SLx share most of the internal hardware and the core software, it's not 100% the same, and those differences, no matter how small they are, must be taken into account when compiling and adapting the software for a given platform.  Take the SL2-s, as far as we know, the sensor has no equivalent over in Panasonic land, and therefore the AF system must be optimized for it. I work in IT, you won't believe how many times a small hardware change can break everything on the software side and viceversa.

BernardC Posted October 6, 2021 Share #149 Â Posted October 6, 2021 Further to this, it's not an easy problem to solve. Photographers have been struggling with the problem of placing focus on faces since the first portrait was made. I had the great luck of learning "Hollywood-style" portrait techniques from a retiring photographer, while I was in my teens. We shot in a studio with a 4x5 inch portrait camera. His technique was the result of years of experience. Basically, if the camera was placed over one X on the floor, and the subject was placed over another X (sitting on a high stool), and his soft light was exactly arm's-length away from the sitter's face (180cm or so), he knew that he could get nose-to-ear in focus on Tri-X at f:16! F:11 would have made the nose unsharp, and killed the rim-light effect over the hair. F:22 would have been too much for the flash system... Equipment is more sophisticated now (arguably), but the aesthetic issues are the same. We are very harsh judges of human portraits. Photographers know exactly what they want sharp, what they want slightly blurred, and what they want to throw out of focus. Getting those results is exceedingly difficult if we can't trust our tools (and judgment). That's not to say that any one piece of gear will work best for everyone. I personally like the SL's EVF, and the way it allows me to judge the spread of focus. Others prefer to work with different tools, and that's OK, provided that they are getting results that they want. 2 Link to post Share on other sites More sharing options...

I work with real-time embedded systems and let me tell you that it only gets worse the more low level you go. Different sensor reading out speeds results in different latencies and all of this needs to be accounted for and the only way to do this is through rigours testing in lots of different test environments which is very expensive.

Yes, and when you think you found the solution, you discover that your solution is introducing new regressions somewhere else. Been there, done that. Link to post Share on other sites More sharing options...

The sony a9 was a bazillion times better here as you could use the center af to focus/recompose on a face, and it'd then stay on that face like glue. But anyway, no complaints here. I'll use the face detect stuff with portraits, and switch to another mode when there's a few people in the scene.   I am new to the SL2 and a complete neophyte with face/eye detection, but I was playing with the new update and found it works well. I haven’t had a chance to play with it much when there is more than one person in the scene, but when you bring the camera up to your eye, it starts looking for people and faces right away and puts boxes around then in white and then selects one with a yellow box. If it chooses the wrong one you can shift to the other one using the joystick. When you now half press the shutter it seems to lock on well to the one select. At least, with my limited experience, and not sure if that is of any help with your issue. Link to post Share on other sites More sharing options...
zaolaotou Posted November 3, 2021 Share #153  Posted November 3, 2021 I have just updated my SL2 to F/W 3.0.  I found that the date and time and no longer be set inside the camera.  They can be sync via Leica Fotos over the smartphone though.  Did I miss something or have done some stupid operations?  Anyone experienced the same?

I work in IT, you won't believe how many times a small hardware change can break everything on the software side and viceversa. It is good that you have IT background and can share your valuable experiences and opinion with us. It is my assessment coming from the manufacturing management background that Leica AF system is likely wholesale licensed from Panasonic. Leica is only a USD$300mil company. A SME by global definition. It would mean almost impossible to have the resources to design and have it's own AF algorithm & hardware design from scratch. There can be minor tweeks from Leica in GUI of Leica products to differentiate it from Panasonic cameras. However if you look at the number of AF sensors of both Leica & Panasonic, they're identical but very different from Sony & others. I am very sure the face/ body detect AF from Leica & Panasonic is identical. Leica likely do not display the cross over the eye although the sensor does track the eye (only logical to think so). The misses in focusing on the eye should happen equally on both Panasonic & Leica cameras (please tell me otherwise if you have different experiences) as the processing power & speed is the limitation (hardware of IC limitation).

There can be minor tweeks from Leica in GUI of Leica products to differentiate it from Panasonic cameras. Yup. What is surprising to me, is that it took Leica about 9-12 months to optimize Panasonic's firmware for the SL2s. The S5 was released in September 2020, the SL2s 2.0 update in June 2021. That's 9 months, maybe more if Leica engineers had had access to pre-production firmware a few months before release. This makes me wonder about their engineering team. It must be really small. Re: differences: I didn't see any notable difference between the S5 and the SL2s, maybe the S5 was a hair faster, but hard to tell. Basically in real life use the difference was zero. I came to this conclusion after having both cameras at the same time for 3 weeks. Link to post Share on other sites More sharing options...

With respect, Leica invented autofocus before selling the technology to Minolta who first used it in commercial applications. They are a small company but they have a lot of know-how. Much of that is optical rather than software, but they clearly seem to have good people working with their color science. I think it is natural to assume that Panasonic does the heavy lifting in this case, but I assume Leica is responsible for integrating it into their user interface and displays etc. Link to post Share on other sites More sharing options...
