Sensor: 24.2MP APS-C Exmor CMOS sensor. This is significantly larger than a smartphone sensor, allowing for better low-light performance and natural background blur (bokeh).
Video Quality: Excellent oversampled 4K at 24/30fps. While it lacks 4K 60fps (found in the newer Mark II), the footage is crisp and professional.
Autofocus: Industry-leading Real-time Eye AF and tracking. It locks onto your eyes instantly and won't lose focus even if you move around the frame.
