Now that the Z6 III has been announced and I can say that I have one in hand for testing and begin showing images, it's time to answer some of the questions I've been getting about the camera. This article will live at the top of the site news for awhile, after which I'll move it to the Cameras section, then eventually deprecate it as I did with all the other early FAQ articles on previous cameras.
In no particular order (though with newest ones in green at top):
What's Touch Fn? A new control function (CSM #F4) that lets you define part or all of the Rear LCD as a touchscreen while you're looking through the viewfinder. You can move the focus point, switch eyes, toggle the framing grid or virtual horizon, and zoom to the touch point.
How many frames in a multiple exposure? Two to ten.
Can I bracket increments more than three stops? No. You can bracket three, five, seven, or nine frames. If you set an increment of greater than one stop you can only bracket three or five frames.
Does the viewfinder always show DCI-P3? I don't think so. There's a very noticeable brightness and gamut change when you set Tone mode to HLG (e.g. HIEF). The same thing happens when you set HLG in video (N-Log is a linear format that looks dull in the viewfinder).
What's the DX image size? 3984 x 2656, or 10.6mp.
Can you use flash in silent mode? Sort of. up to a 1/60 flash sync. You set Camera sounds to Off and CSM #D6 to Electronic shutter.
Is Release mode saved in U# settings? Yes.
Does it have Full and Quick format for CFe cards? Yes.
Which second slot card functions does it have? Overflow, Backup, RAW primary — JPEG secondary, and JPEG primary - JPEG secondary.
Does it have High-frequency flicker reduction? Yes, it's just an On/Off function, though, and you have to manually figure out the shutter speed to use.
Can you assign spot metering to a button? Yes.
Does multiple exposure create a raw image? No, though you have the ability to save the individual photos in raw.
How do you set the audio input to line? VIDEO RECORDING > Audio input selection.
Does the mic jack provide power? Yes: VIDEO RECORDING > Mic jack plug-in power.
Does it have Hi-Res Zoom? Yes. Maximum is 1.4x.
Does AF-C show confirmed focus? Yes if you set it with CSM #A10.
What's the buffer like? Essentially infinite with a CFe card. However, note that you need to set infinite in CSM #D2, otherwise you'll stop at 200.
Is there an Exposure delay mode? Yes.
What grid types are supported? 3x3, 4x4, 5:4, 1:1, and 16:9.
What can't I assign to button on the Z6 III that I can on a Z8? I'm not going to do this for everything, as the combinations and permutations go on and on, but for the Fn1 button and CSM #F2 the missing functions are Preset focus point, Cycle AF-area mode, Recall shooting functions (both versions), and Shooting menu bank (obviously). New functions include assigning each of the metering modes, as well as Enable/disable touch Fn.
Can you lock the Direction pad? Yes, with CSM #F5.
Does it have the series playback options? Not all of them, but it supports series playback pretty well.
Does information rotate when you hold the camera in portrait position? Yes by default (can be overridden).
Do the displays show distance? Yes, in feet or meters.
How about IPTC data and voice memos? Both are included.
Anything else new? Curiously, there's now Connection options for Nikon Image Cloud, which allows you to connect only under certain conditions (camera off, only when powered by USB, etc.).
Does the camera support the ML-L7 remote? Yes, you'll find the necessary setup in the NETWORK menu.
Can you connect via Ethernet? Yes, with the correct dongle on the USB port as well as the right setting in NETWORK > USB.
