The sensor inside the Leica M10 is not the same as the sensor in the Leica SL

After publishing his Leica M10 review last week, Sean Reid ( posted a new article comparing the color, resolution and noise performance (at various ISO levels) of the Leica M10, M 240 and SL cameras. With Sean's permission, I will share two conclusions from his review (Reid Reviews accepts no advertising and is supported by subscriptions only):

  • The Leica M10 has about a 1.5 stop high ISO advantage over the Leica M 240. Keep in mind that the differences in noise levels, at very high ISO, between the SL and M10 are not only due to sensor differences. The size of each camera’s body, and thus its ability to dissipate heat, is also an important factor.
  • The Leica M10 and Leica SL do not have the same sensor and Sean's test results clearly show that (hint: the SL has better performance at very high ISO).

I will do some comparisons between the Leica M10 and Leica Q later this week and will post them online.

    Interesting Review and photos:
    I’m not sure that SL has a better performance at very high ISO.

      I agree. As Sean acknowledges the SL files in his test are slightly darker in the shadow areas, exposure wise, and this may have accounted for the perception that the SL had less noise.

    from the dng files im seeing so far the m10 colors look better than the leica q. richer/brighter tones.

    • it’s probably from the better lens 🙂

        Will you test M10 by using pre-digital optimized M (or screw mount) lens?

        • Unfortunately I do not own any old Leica lenses.

      • eric

        is it the 50mm f/1.4 ASPH?

  • But they did say so since day one, that this was not the same sensor as the Leica SL and Leica Q. I wonder if it’s also from Towerjazz or if Leica ended up choosing Sony instead.

    • I honestly hope it is not a Sony Sensor.

      • no, it’s not

        • oh good, because I really dont like how the colors come out for Sony’s even for xtrans+sony they just seem so artificial :

          Peter, from our interview, they said that the sensor are made from many sources. Have you get my e-mail about link to interview?

          • Yes, did not have a chance to read the whole interview yet.

      Ah, the old German-Japanese pact…

      • Hence, X Systems (Axis) I’m totally kidding lol.

    could it be a variation of the same sensor + firmware ?, did he pull the camera apart to to see what sensor was used !
