Surely the headline here is the extended ‘S’ensitivity and boost in low light performance without giving up any of the main features of the SL2 (bar resolution).

I’m not sure what is so ‘sexy’ about high resolution anyway for the average user making nice prints, and certainly for the hybrid video shooter.

Agreed. The high resolution is fantastic if that is your main goal, but I do miss the manageable megapixel count and low-light sensitivity of my old A7 bodies. I made the jump from Sony at the beginning of the year, which I don't regret (even with their new A7Siii out now), but I do hope the SL2-S serves the low-light community a little nicer. My personal reason for the SL2 was for the better video capabilities, reliable photography system, and overall brand recognition (it started getting a little weird seeing wedding guests pull out their Leicas while I'm still using years-old equipment). I do believe it is the artist behind the camera, but it would be fantastic to match a personal/business brand aesthetic with the equipment of choice. If anyone is interested, I just placed my SL2 for sale 😅

The camera will probably be announced in December, but that is too late for the Xmas business. Then also the worldwide Covid crisis. And with 24 MP it is not terribly sexy. (Similar to what others offer since 1 or 2 years at an entry price. OK, body and CPU will be better than these entry offerings, but still.) Will this be a good business for Leica or maybe rather a flop ?!

I think they take a lot of risk, for “little” gain.

The SL2 already created a bit mixed impressions over the original SL as realy not everybody wanted more megapixels, but they wanted the IBIS or other new features, so this model was absolutely necessary and it is not suprising they've kept the same body to keep it simple and straightforward (and to sell at a more profitable price).

24MP is a much better fit for a hybrid camera, here are some reasons why:
- better ISO from the sensor means better AF in low light, less noisy EVF in low light
- faster readout means better video capabilities and more usable electronic shutter for a completely silent operation (less rolling shutter )
- very sharp FF 4k video (up to 30p) without pixel binning or line-skipping with Leica colours
- less data to process for stills as well (to dual SD cards), it won't bog down when shooting multiple bursts (quicker to review or to batch post-process as well)
- more affordable, great companion to the SL2, same ergonomics, etc.

Different models for different needs, but many shared parts, it is exactly what they need to do.
This camera is probably going to be very popular, as there are so many people out there with a nice collection of vintage glass and now they can use them to shoot stills and video with them with great results and this camera won't have the smearing problems present in Panasonic bodies (unless modified=no warranty).

The one factor that stands out from my experience with the M10R is the value of good technical skills. High resolution cameras essentially “amplify” everything greatly, whether it is camera shake caused by poor hand-holding technique, shutter vibrations originating from the camera, poor focusing technique, unstable tripod, slight wind or other various causes of blur in images such as my hand tremors. IBIS is important and now I can choose between sensor size. Large pixel vs small pixel, the debate continues.

??  To be clear, sensor size is identical between cameras. No choice on that basis. Just different MP.

Jeff, for some less pedantic types either characterization seems to work. I don’t disagree with you, just saying.

There HAS to be some skipping/binning/mixing to get a 4K image from a 24MP sensor in FF, because 24MP equals a 6K image. In real world, pixel to pixel readout does reduce readout time and alliasing, but produces a less sharp image because there is no downscalling.

A 9Mp (UHD) or 12MP (DCI) sensor pixel count is sufficient to give you a pixel-to-pixel image on FF size.

24MP is 6k FF, or 4K s35 (like the old SL did to shoot video.)

36 to 45MP (depending on w/h ratio) is 8k territory.

The "real" pixel to pixel ratio of the SL2 is to be found in s35 5K mode, in 4/3 ratio. I wish they will make this one compatible with 422.

Yes it is downsampled from 6K (up to 4K30p with 4K60p it will crop to APS-C mode) so unlike the SL2 it will keep the dynamic range and signal to noise ratio high for video, it should be about two stops better with regards to ISO for video, a big difference.
And yes due to line-skipping the SL2 has slightly better rolling shutter in FF (1.09x crop) mode (About 16ms versus 20ms) but for stills images with the electronic shutter the SL2-S will have way less rolling shutter.

I am not sure the SL2 uses line skipping, but pixel mixing... that can explain the alliasing issues in some FF modes.. which also give us this wonderful sharpness in the image. In s35 the rolling shutter falls below 10ms and is very good. I am still getting more jobs in still than moving image atm, but pairing/downgrading to SL2-s could be an interesting options for video work indeed.

As with the Panasonic S1 or S5 cameras, they can also enable C4K(up to 60p) Prores RAW HDMI output in the APS-C crop mode on the SL2-S, it is something that might be coming many months later after its introduction, and it would lift it further ahead from the SL2 for video and to keep the demand up.

I find it interesting at all the criticism directed towards the camera. Leica is doing what every single other company has done, which is to sell a lower res version of the same body to market to people who: 1. Do not care about resolution. 2. Prefer better high ISO performance. 3. Want better video. 4. Want to pay as little as possible for the modern tech. If you don't want to do that, you can get the more expensive higher resolution model, which in this case is the SL2. They are doing literally the exact same thing as Sony, Panasonic, Canon and Nikon. Clearly this is a strategy that works...you save on all the tooling and R&D of creating a completely different body, and you satisfy a greater proportion of users. If you introduce the more expensive one first, you get more buyers at a higher profit as well, as you sell cameras to the people who would want that body, but also to the people who would be satisfied with the cheaper one, but prefer to buy the newer model immediately. Those same people might still buy the lower rez body later, meaning you get two sales. Once you are done satisfying demand for the higher rez body, the lower cost one comes out and you get a wider group of buyers as well as some of the initial group who might have wanted it as a backup or for the low light/video abilities. It seems like this is one of those cases where everybody wins...buyers get more choice and the company gets more sales for minimum additional effort.

Yes, in FF the SL2 uses pixel mixing.   Sensor readout is 1/60 th second (16.6 ms).  In crop mode (s35) it is less than 1/100 th s = less than 10 ms.         (It makes good use of the Maestro III)

The Sony a9 II is faster, but this is probably not the new sensor for the SL2-S , or is it ?  The predicted price is higher than the a9, so they could maybe afford a high end sensor in the SL2-S....  But Sony will maybe not give it away, unless they have something new that is better.

It is a BSI sensor, does this mean it is from Sony ? Or do others also produce BSI sensors ?

I bet it's exactly the same as the S1R, so pixel binning, it does not matter how they are naming it.
Probably same 1.09x crop, same rolling shutter, except the S1R is more crippled for video, regarding no Log and more compressed codecs.
The S1/S5 sensor is simply a better fit for video as you can see in this comparison (except the 1.5x crop 4k60p versus 1.09x crop, but worse quality)

There is a description in the web. It is definitely pixel mixing for the SL2 in FF mode.

It is in a video magazine (I think from UK), from Nov 2019. I try to find it again.

It does not matter, if the quality, rolling shutter, 1.09x crop is exactly the same as the S1R, it is the same thing, e.g. pixel binning with a puffed-up name. Only the codecs and the presence of Log which are different. It does not mean that the SL2 is not a quantum leap over previous Leicas for video.

But not compared to other mirrorless cameras, and the SL2-S is more up-to-date while being cheaper.

And no, it is not the same as the S1R. (Why do you say that ? You did not verify.) Just the sensor resolution is the same. The SL2 is much faster. Why else offers the S1R 9 FPS and the SL2 20 FPS.   Check the specs. Also the video specs are clearly different. (Too complicated to write down here. Simply compare the official spec sheets).

I found the description again, It was in the fdtimes.(= film and digital times) In the article below (Report on Leica SL2), in the section  Leica SL2 for Cine . (Pixel mixing    and following lines).

https://www.fdtimes.com/2019/11/06/leica-sl2/

The explanations are written by Stephan Schulz. Who if not he should know the details better ?
