Startup time is slightly slower than my Z9 but it is still pretty fast. Feels like it's under 1 second whereas with Z6ii it's definitely 1 second or more.
There's also no delay when turning it off, whereas on Z6ii it takes a second delay before it shuts down.
Received my Z6 III an hour ago. Have lots of tests planned.
First up - base ISO dynamic range comparison between the Z6 III and Z6. ISO 100, Minus 9EV exposure, Zeiss 100MP, WB Cloudy, Electronic shutter. Processed in ACR/LR with respective camera-neutral matching profiles, all developer settings zeroed out, 45/0.7/35 sharpening, Chroma+Luma NR disabled. Framing is a little off due to my Z6 L-Bracket vs Z6 III temporary base bracket but the exposure is perfectly matched.
Z6 III definitely looks to have lower base ISO DR. I put this test together quickly so I'm reserving final judgement in case of methodology errors from my haste to get something posted

I would like to hear your thoughts on start-up times and wake-up times between Z6 and Z6III please.

Love that HE* file size is only 16-17MB instead of 26-27MB on my old Z6ii. Photos are loading up faster for me on file explorer.
HE* is the biggest game changer that Nikon has in their armory IMO. It's a perfect file format. Now if we could get Apple to friggin support thumbnails for it on Mac OS and iOS!

Interesting. I guess its that partially-stacked sensor contributing to the DR hit
I have a running thread on DPR where I'm posting all my findings. I know many around here don't like visiting DPR but posting the same information on both sites would take up time I'd like to spend on the testing. Here's the link:
Thanks for all the early work you're putting in looking into this camera's performance and behaviors, much appreciated!
It's not clear what one is looking at here in your ISO ramp animation...RAW stills images? Video frame comparisons? etc? Clarification please?
I ask as the only other full ISO ramp test I've been able to find for Z6III (thus far) is Julia Trotti's "JPEGs SOOC...noise-reduction set to normal" ISO ramp sequence (queued to 13:02 mark)...
Nikon Z6III Hands-On Review Photo and Video - YouTube
&t=745s
...which does not show the same, er, "poor" under-ISO800 noise performance as your ISO ramp animation?
Also, Gerald Undone suspects "what appears to be a noise improvement at ISO6400", his more-limited ISO ramp test (he only provides images from ISO800-up) and observations here (queued to 7:10 mark)...

...where he posits "...so perhaps that's this sensor's 2nd native ISO".

So far so good with my Sony lenses and megadap on the z6iii w/ Sony 24-70gmii. AF lightning fast on photo. Still have to test more for video.
Thanks for that report, Jason, I've been looking into duplicating my L-mount Sigma 14mm f/1.4 DN Art with the E-mount version to see how it performs on Z-mount via the Megadap...you've given me some hope!

Hi Jimmy,
In my ISO test I'm using a fixed exposure (aperture, shutter speed) and only varying the ISO between raw images. At ISO 100 the scene is -7EV underexposed. I pull all the raw images into ACR/PS and then normalize the output brightness to be the same for all images. For ISO 100 that means +7EV exposure in ACR/PS, for ISO 125 +6.66EV, for ISO 160 +6.33EV, etc...
By using a fixed exposure I'm isolating any noise difference to ISO gain alone. Most people who do a noise ramp vary the exposure and ISO together, so that they reduce the exposure (ie, faster shutter speed or small aperture) as the ISO increases. That matches how people actually shoot in low-light conditions but by varying the exposure they're incorporating not just ISO gain noise differences but differences in shot noise.
Gerald's ISO 6400 comment is for N-Log, which uses a sensor ISO that's -3EV below the notional one, which means N-Log ISO 800 is actually sensor ISO 100...and N-Log ISO 6400 would be ISO 800. You can read more about how ISO is managed for N-Log in my thread here:

Seems to be the same. The question now is the sensor thickness of the Z6III vs the Zf, I guess.
I like the looks of the Zf, but not the handling, otherwise it would be an easy choice.
The Zf looked intriguing to me as well. I wanted better AF than my Z6, but after holding the Zf for a few minutes, the body was too thin for my hands. Glad I waited for the Z6III. It’s a great replacement for my Z6 and very similar to my Z8, so it will serve as a backup and for low light shooting (events, etc.).
