Nikon listened: Changes incorporated in its Z 6II camera—the update to its highly successful mirrorless Z 6—reflect the company’s response to user criticisms of the initial model. Nikon also added features but didn’t change the base price. The Z 6II retains the excellent ergonomics (including menu structure), control layout, and image quality of the original. But does the Z 6II offer enough features to move Nikon DSLR users to mirrorless?
Reviewers and early critics of the Z 6 were quick to point out the lack of a second media slot in the camera. Many professionals, including me, prefer to record raw and JPEG captures on separate cards. The Z 6II now includes two card slots: a CFexpress (type B)/XQD slot and a UHS-II SDXC slot. This necessitated a 0.1-inch increase in the thickness of the body and, along with other changes, a 1-ounce increase in weight. I couldn’t tell the difference until I tried to attach my Z 6 Arca-Swiss baseplate to the Z 6II and noticed the different fit.
The Z 6 was initially criticized for not always nailing the focus on eyes, though in my experience its face-focusing algorithm always worked fine. A firmware update added eye focus for humans, dogs, and cats as a selection in the Custom Functions menu of the Z 6. The Z 6II improves on this by adding new options in the Custom menu and in the information button and its icon display. Along with established auto eye focus functions, eye detection for humans and animals is now available in Wide-Area Autofocus mode. Select a section of the scene, and the camera will focus on all sets of eyes in that area. This will correct the automatic detection’s tendency to jump around when you’re photographing groups or when the subjects are arranged in depth and you want to focus on a specific person.
Videographers will find much to like with the new video capabilities of the Z 6II besides the additional power options. The Z 6II provides 4K (UHD) 60p recording with full pixel readout as well as eye-detection autofocus mode, surely a blessing for wedding and event photographers. You can capture 10-bit N-log and HDR (HLG) output for more detail, dynamic range, and contrast, but you’ll need an external recorder that supports 10-bit video. An optional 12-bit ProRes Raw and Blackmagic Raw upgrade is also available. Even 120p full HD recording is available, which you can play back at 30p, 25p, and 24p for smooth slow-motion effects. You can also reverse the focusing ring direction of Z-series lenses to match the direction of many non-Nikon cine lenses.
Every upgrade to hardware and software boasts increased speed by the manufacturer, and the Z 6II really delivers. This is due to the second Expeed 6 image processor in the body. The additional processor improves processing speed across the board, including upping the camera’s burst rate from the 12 frames per second of the Z 6 to 14 frames per second in Continuous High shooting mode. Nikon states that the buffer capacity is 3.5 times that of the Z 6, which would put it upward of 105 frames, with higher rates depending on capture mode and capture card. Along with the MB-N11 battery grip, the Z 6II becomes a formidable camera for capturing sports of any type.
The big difference I noticed every time I used the Z 6II was how much faster it woke up from sleep between shots. The Z 6’s delay can be annoying at times, but it’s barely noticeable with the Z 6II.
I found another improvement when I was photographing in low light, which I do a lot. In every low-light situation I threw at it, the Z 6II quickly focused without hunting. It seemed faster than my Z 6 in these cases, and Nikon confirms that autofocus has been improved by one EV at the low end. Because it has excellent low-noise performance at high ISO settings and 5-axis image stabilization, I could comfortably expose at 1/125 second and f/5.6 with my Z lenses and Auto-ISO enabled without concern when the ISO hit 12,800-25,600.
Building on everything I like about my Z 6 and incorporating corrections to its shortcomings, the Nikon Z 6II offers enough features to convert even diehard Nikon DSLR users to mirrorless Z users. The latest amazing Z-series f/2.8 lenses, along with the ability to use legacy Nikkors, is the final determining factor. MSRP of the Z 6II is $1,999.95, identical to that of the Z 6 when it was first introduced. The Z 6II is also available with the Nikkor Z 24-70mm f/4 S lens for $2,599.95.
Shorter battery life compared to DSLRs is a fact of mirrorless camera design and a source of criticism for the Z 6, so Nikon introduced the new EN-EL15c battery with 2,280 mAh 16 Wh capacity to improve on the EN-EL15b battery with 1,900mAh 14 Wh capacity. The good news is that all En-EL15 batteries are compatible with the Z 6II.
My strongest criticism of the Z 6 was that its design didn’t allow for attaching a battery grip with controls for portrait-orientation shooting and increased battery capacity. That didn’t stop me from buying a Nikon MB-10 Multi Battery Power Pack as soon as it was available. That added an additional battery and the ability to swap depleted batteries during extended sessions but no portrait-orientation controls.
The new MB-N11 Power Battery Pack for the Nikon Z 6II accepts all EN-EL 15-series batteries and includes a vertical shutter button along with main and sub-command dials that perform the identical roles to those on the camera. It also has three controls you can program in the camera menus: Function (Fn), AF-On, and a Multi-Selector button. These are programmable to the same level as the corresponding buttons on the camera, which is extensive. The MB-N11 even includes a storage compartment for the camera battery door that must be removed from the Z 6II to attach the MB-N11.
The MB-N11 allows the batteries to be charged while in the battery pack, but the batteries’ operation is significantly different from the MB-N10 for the Z 6. In the Z 6 battery pack, power is drawn from one battery until it’s exhausted, then power is drawn from the other. While the exhausted battery is replaced, power is drawn from the other battery until it’s exhausted. You can alternate replacement ad infinitum while the camera remains powered. Each battery has its own access door.
The Z 6II battery pack uses a tray to hold the two batteries with only one access door for the tray. Power is drawn first from the battery closest to the door until it’s exhausted. You
can replace that battery while the camera draws power from the second battery. When the first battery is replaced, power is drawn from it again until depleted, then power is drawn again from the second battery. If during the course of a session the second battery becomes exhausted before the battery closest to the door is replaced, the camera will be without power. It’s possible (though unlikely) that this could be an issue with prolonged video capture. For truly unattended stills or video, Nikon provides a way to attach a dummy battery that can be attach to a high-capacity external battery or main outlet.
There’s also a USB-C port on the MB-N11 that can be used in conjunction with the USB-C port on the camera. When used together, the camera port could be dedicated to tethered shooting while the battery pack is powered. Charging while powering the camera requires an EH-7P AC charging adapter.
