• Slow continuous shooting speed: The 4.5 frames per second continuous shooting rate is not ideal for capturing action or fast-moving subjects.
• Outdated technology: The 6D is a relatively old camera, lacking the advanced features found in newer models, such as 4K video recording and touch screen functionality.
