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.
