Revolving around a 24.5MP BSI CMOS sensor and dual EXPEED 6 image processors, the Z 6II is characterized by an increased buffer depth and faster continuous shooting rate, up to 14 fps with single-point AF or 12 fps shooting in other focusing modes. Video recording at UHD 4K 30p is possible, or up to FHD 120p for slow-motion output, and external recording gains 10-bit out along with N-Log and HLG (HDR) support. The sensor also suits working in a variety of lighting conditions, with sensitivity from ISO 100-51200, and in-body 5-axis Vibration Reduction reduces the appearance of camera shake for sharper handheld shooting. Additionally, the sensor also incorporates a 273-point phase-detection AF system, which now supports Eye-Detect AF in Wide-Area AF modes and during movie recording, and permits focusing in low-light down to -4.5 EV.
Balancing the imaging, the Z 6II retains its overall physical design, however it has been updated with a new dual memory card slot interface to hold one CFexpress Type B card and one SD UHS-II card for more flexible storage. Both a high-res 3.6m-dot OLED EVF and rear 3.2″ 2.1m-dot tilting touchscreen LCD lend versatility to image composition and playback, and SnapBridge wireless connectivity can be used for remote camera control, image sharing to a mobile device, and even over-the-air firmware updates.
