1. Canon EOS R6 III: Technical Overview

1.1 Sensor and Resolution Upgrades

The Canon EOS R6 III features a newly developed 33-megapixel full-frame CMOS sensor, an increase from the 20-megapixel sensor in the EOS R6 II. This bump in resolution strikes a balance for photographers who desire higher detail without sacrificing low-light performance or increased file sizes. The sensor's backside-illuminated design enhances light gathering, contributing to Canon's signature image quality.
