Leica M24o (M Type 240)

Sensor Aliasing (Checkerboard)

All Bayer matrix sensors produce various types of aliasing, particularly those without an anti-aliasing filter (optical low pass filter).

The Leica M240 is no exception. With its 24 megapixel sensor, one can expect fewer issues in general due to a higher photosite density, but it nonetheless develops some unavoidable effects with particular subject matter.

Example — “color ringing ”

This actual pixels crop is from the Focus Shift (dolls) page.

The term “color ringing” is used here, this is not an official term, just a descriptive one.
