They are not using Sony sensors. They are using CMOSIS sensors (which has been acquired by ams).

Fujifilm, Nikon, and Panasonic are using Sony sensors, however.

- Each company has unique glass. - Each company has unique physical control schemes and software UX. - Color profiles allow you to apply the color science to RAW files. Some apps will automatically apply the color profile you select while shooting when you are processing later.

My response was addressing the perennial partisan quips that brand loyalists in the camera scene have about preferring one brand’s color science over another. I’m basically saying it’s moot if you shoot raw because your color grading can be as wild as your dreams in post. Unless you’re a live journalist, you probably should be shooting raw.

-Name, aesthetic and UI. Rangefinder cameras do have their purpose still - being able to see what is going on outside the frame is a great aid, as is its ease of focusing in low light.

And, to a lesser extent now that mirrorless cameras are a thing - their unobtrusiveness.

> Leica is using Sony sensors

Do you have a source for that? As far as I remember they have been very secretive about their sensor supply chain.

Some Leicas use CMOSIS, others used Sony sensors. In any case, Sony makes the best sensors by a mile.
