- Comparison of the base ISO (100) dynamic range between the Nikon Z6 III and Nikon Z6. A scene was set up and metered for a normal, centered exposure. It was then progressively underepxosed in 1EV increments until reaching -10EV of underexposure. The results raws were pulled into ACR/Photoshop and their exposure adjusted in post to match the original centered exposure. All ACR settings were cleared except for sharpening (45/0.7/35). Both Chroma and Luma noise reduction were disabled. The Camera Neutral-matching profile was used.
Both cameras were fitted with the same copy of a Nikon 50mm f/1.8 S lens. The electronic shutter was used on both cameras.

My Nikon Z6 III vs Z6 High ISO Comparison is here: th-cam.com/video/TGh1E2eiybc/w-d-xo.html
My Nikon Z6 III sensor readout speed measurements: th-cam.com/video/WkCEYg_mOo0/w-d-xo.html
for me the highlight lattitude and clipping is really important too. The z8 has similar dynamic range to my d800, but the blue channel clips first. THe practial upshot that I deal with day in and out is that overexposed skies go grey on the z8 where I can still pull blue from the d800.
I'd also love to see info on the video dynamic range too, but appreciate the amount of work its takes to make something like this! So thanks for the real world demo - it's invaluable
You didn't mention the Z6 has the visible AF sensor banding in the shadows. It shows up as horizontal lines. You can see this even in your TY footage. (The Z6II corrected this.)
Would be nice to see how DXO noise reduction handles both versions of the camera.
With the move to phase detect + stack sensor (partial z6iii) it seems the dynamic range is a little short infavor of speed. Knowing the characteristics of my Z8 at 800 and seeing the Z6iii partial stacked vs the BSI cmos definitely feel there is a limitation to the "cross talk" of stacked sensors meaning the boosting has to be scaled back
Will you make a video comparing the different iso between z6iii and z6i?
I just posted my ISO comparison: th-cam.com/video/TGh1E2eiybc/w-d-xo.html
Sadly, Nikon went only for speed with this update of the z6. I was hoping for a bit more image quality as well. I think, for its price (in Europe 3K) they could have implemented a fully stacked sensor or upgraded to 33 Mp. Furthermore, I have to decide now if I go with z6III or z8 (a bit big for my use case)
I was hoping for the same 33mp but anyhow the autofocus is improved it has smaller body than the z8 and still very powerful for videos
Speed is kind of the most important update for this body as it effects rolling shutter which is critical for video and AF performance. 95% you can run electronic shutter which keeps wear and tear down, that's pretty awesome. Some day in the future it'll probably be fully stacked and over 30mp.
@@Frippin-MTBD80 Speed is important but dynamic range as well ;) ...I can get the even faster, full stacked, 45Mp , Z8 for €3600. That's at the moment only €600 more. A bit too close, in my opinion. For €2500 I would take the Z6III without thinking.
NikonRumors said a few hours ago says Nikon has registered a 2nd unannounced camera in Asia. Maybe that will be a z7iii which I would imagine would be photo centric and your ideal camera.... Keep an eye out within the next 6month ;D
@@zetknight i hope not right now i just ordered the z6 iii😂
A better IBIS and autofocus system will more than compensate for the lower dynamic range.
So you'll get more hits but they won't look as nice
@@StriderGTS better have more keepers than a slow focusing camera which has a high rate of missed important moments.my main gripe over the Z6/Z6II..my clients don't pixel peep either, they are happy looking at their iPads and smartphones tiny screen.
Already canceled my order of z6iii. My z6 sucks in dynamic range in video and i can't go backwards.
Why not do the same for the highlights. I am used watching the camera dynamic range test on CineD. Even if it is for video, the latitude test goes in both direction because different camera are balanced Shadow/highlight differently.
Because these sensors have similar saturation points, so there's no material difference in full-well pixel capacity. The notion of "highlights" vs "shadows" as most understand it is merely a metering construct and not a property of the sensor's dynamic range.
@@testcams It is not necessarily true, you have different tech etc that can make a difference. Looking again at the latitude test on CineD, to take the most consistent sensor size resolution, that is 8k FF. For example The Z9 was 4 stop over and at best 5 below. It scored 8+, perhaps a 8.5-9 stop , the Sony A1 (Not in Raw) was about 8 th. But latest Sony Burano was a 10 stop sensor. The first camera to reach the original Arri Alexa 10 stops of latitude.
The tint is inconsistent in Z6iii as BIll Claff showed. Also I suggest comparing to Z6ii, which has much less tint.
Was the Z6III set to use the electronic shutter or mechanical?
Both cameras were shot with their 14-bit readout electronic shutters, which have identical noise performance vs their EFCS/fully-mechanical shutters.
Hey, great test, can you do the same with the ZF? This should be the same sensor as the Z6II, but with the new AF it could be cool to check the impact.
I've tested the Zf but have since sold it. It measured with the same amount of noise vs the Z6 and Z6 II.
@@testcams Ah great! Why did you sold it if you mind me asking? Fell its the best bang for buck out there at the moment.
I only purchased the Zf to perform my tests on it. I'm a fan of the more traditional ergonomics available on the Z6/Z7.
@@testcams It makes sense! I am considering a second ZF, think it is a lovely camera and in Spain I can get them around 1,6k (tax exclusive) which is insane.
Not sure it’s great to sacrifice dynamic range, which most photographers care about, for sensor speed, that only some photographers (and videographers) care about. Wonder how it compares to the older 24mp sensor in my Z5?
This ultimately confirms that all I really want is a Zf in a contemporary body (Z5II ;)
Not just speed.... AF is far much better.. is a complete new camera. Maybe it has a bit less DR... ok, but it gives you almost flagship performance
True, but the Zf also has very good AF, and may be a better fit for those who don’t need the speed or video specs of the Z6III. I just don’t love the retro ergonomics.
thank you, at least the new z6 iii doesnt have banding
I'm not a professional photographer, but to me, and please correct me if I'm wrong, the new camera makes a totally unusable image a bit less unusable but still unusable.
I understand that some pictures have to be taken under extreme circumstances and an unusable picture is far better than no picture,
At the end, looks like if you don't need the high end video specs of the new camera you could be perfectly fine with the old one, which by the way could be find used in pristine conditions for one third of the price to the new one.
That's one way to look at it and perfectly reasonable. I might describe it this way - there's a point of underexposure beyond which both cameras produce unusable images. That point occurs earlier on the Z6 III than it does the Z6/Z6 II.
all good but this type of comparison begs 4k upload
I agree with you. I'll definitely consider 4K for future comparison videos like this.
It maybe worth to mention that the construction of the Z6iii sensor allows for much greater reading speeds, which results in much less distortion of moving subjects, which may be the cause of this difference. And of course some noise reduction might be performed even even when no noise reduction selected in Camera Raw, or Camera Raw is not good enough yet. It would be interesting to see what would Nikon's own RAW processor do with these images.
And just keep in mind as the sensor response to light is linear while our eye (and film) is logarithmic. That is the top half of the dynamic range is one stop, the half of that is one stop lower and so on. This means that on the 6 stop underexposed image the -6th stop may contain just a few bits.
The reduction of rolling shutter artifacts on the Z6 III only applies when using its electronic shutter, which at 1/70 still isn't fast enough for many shooting scenarios, thus the EFCS/mechanical shutter must still be used. In terms of other benefits to photography, the Z6 III's faster readout speed definitely aids the AF system but otherwise doesn't provide much benefit. The biggest benefit of the faster readout is on the video side, as it provides a noticeable improvement to rolling shutter since the electronic shutter must be used for video.
@@testcams You are right about the mechanical shutter, but I'm confused by your answer. Why is the shutter speed with electronic shutter only 1/70?
1/70 is a measure of the sensor readout time as depicted in fractional notation. It's the same notation used to describe shutter speeds but is not itself a shutter speed.
I wonder how fuji xh2s is fully stacked with 14 stops of usable dynamic range while z6iii is still competing with z6. That's probably over 2 stops below, fuji. You want speed, you got it, but your dr suffers.
It's simple.
They did what Canon did.
Noise reduction applied in raw files.
So the 6 year old Z6 is better than the new kid on the block. Geeesh. And all for only $3400.00 (body only) here in Canada.
Noise increases as you go from line by line scan to stacked to global shutter. That's just part of electrical properties. So you pick what is more important to you. I'd rather have more speed as I don't need to change EV more than 3EV in post. If you are changing more, this camera is not for you. You need a slower sensor with more dynamic range.
@@mlai2546 14,4ms - really "great" speed lol
@prokremelskidezolati1426 how fast is Sony A7iv? A7Riv? Panasonic S5ii? Let me know when you know of a sensor that has a faster readout speed without being stacked.
The Z6III sensor compromises on DR with scan speed for Electronic Shutter and video performance. Remember that rolling shutter distortion also impacts IQ and the Z6III mitigates this almost completely with the faster scan speed.
Don’t overgeneralise like that. There are 50 other things Z6iii is doing 10 times better. I’ll forgive a less than a stop of dynamic range drop.
Didn't they tell us that the Z6 3 is a stop better in low light?
🤣🤣🤣
It may still be better. Dual gain iso at 6400 for the second base. So, for low light, it's good as long as you're not going to pull shadows, which may be difficult.
If they said that, probably implied high ISO. I’ve never seen a manufacturer advertising DR, it’s just something people test and find out.
Why use time looking at pixels, I don't get it.
Why did you, I don't get it 🤣
Content creators need to keep producing content, and those who can’t make good images will always be concerned with how to polish a bad one.
This could be just a problem of the really awful adobe raw conversion.
Nikon's NX Studio renders similar Z6 III vs Z6 noise differentials for these same set of raw files.
Who would have known a stacked sensor has negligibly worse DR vs BSI CMOS, when the photographer improperly exposes by 5 stops hahah oh jeeze, this videos just prove how foolish these tests are. If people who test for DR knew how a BSI sensor vs BSI Stacked Sensor worked, than they would praise how good the sensor is in the Z6 III vs complaining how "bad" it is. If this is the case, the Sony A1, A9 III is garbage, so is the Z9.
Man most of you won't even notice the difference 😂. But no the z6 gen 1 isn't better. Z63 is much much better overall. You people look at little charts and go by that lol
If jared polin praises tje camera, that's a huge indicator. He has been bashing nikon for ages. If you just want a smidge better dynamic range, over everything, then you get a gen 1 z6.
That's not fair - I sometimes look at big charts too.
@@testcams that is cool. People are just crying babies at Nikon. They cry when Nikon was failing. Now Nikon is making great stuff and doing better and weirdo Nikon fans are like "I'm going to shoot on my DSLR or first gen z6". It's annoying. Like just STFU. Use your old crap or get the new stuff and shut up already (speaking generally)
