- 45-46MP sensor
- Improved low and high ISO
- New and improved version of SnapBridge
- No built-in GPS
- Tiltable LCD screen
- Memory card slots: one SD and one XQD
- New: AF system from the D5
Concerning the EOS 6D Mark II. Please note that we got rumors suggesting Canon may not release an EOS 6D Mark II but a full-frame mirrorless camera instead.
