Nikon Z6 III Review by Gerald Undone

This is the Nikon Z6 III and it is a very impressive camera. In fact, in terms of just crude speed and performance, this is probably the most powerful video camera available for the money from any brand. Let's get undone. (upbeat music) ♪ Gerald undone, he's crazy ♪ - What's happening everybody? I'm Gerald Undone and... As usual, some disclosure, Nikon lent me this camera to make this review. I don't get to keep it. I wasn't paid by them to make this video, and Nikon is actually trying something new with this launch. For the first time, they actually lent it to me before embargo without a chaperone. So I've had it for a few weeks and in that time, I've been able to do whatever tests I wanted and no one was around to supervise and they haven't seen this video before publishing and they don't get any input on its production. However, Nikon did want me to mention that this is a pre-production camera. So keep that in mind while watching. This video does have an actual sponsor though and that's Storyblocks. So let's jump right into what makes this camera interesting. The sensor. It's using this new 24.5 megapixel partially-stacked sensor so only some portions of the sensor have that extra circuitry that make it stacked, located at the top and the bottom to give the sensor an impressive speed boost without inflating the cost as much when compared with other fully stacked sensors. But in order to appreciate that speed, I need to first tell you what resolutions and frame rates it's capable of. So this camera can record 6K at up to 60 frames per second, in full frame without any crops, in raw, internally to the CF Express card, and you can do all this at a sub 10 millisecond read speed. That is bananas. Now that's using Nikon's own N-Raw, but you can also record H.265, ProRes 422 HQ and ProRes Raw all internally as well. But there are different resolutions and frame rates for those. In H.265, you can go up to 5.4K at 60p. In ProRes 422 HQ, it's 5.4K, but 30p max. And in ProRes Raw, it's the full 6K, but limited to 30p as well. All of these are full frame, uncropped 16x9. The only time you're forced into an APS-C crop is if you shoot 4K120. Even if you shoot 1080p, 240 frames per second, you're still getting 95% of that full frame image. But let's get into the rolling shutter results for each of those now. So like I was saying, in 6K N-Raw, I measure a read time of 9.4 milliseconds. This is fantastic. Often full frame cameras in this price bracket take over 20 milliseconds to read their 6K sensors and experience serious jello effects when panning too quickly. But this Z6 III is the fastest full frame camera under $4,000, which is great. And because every one of the other modes is derived from that 6K read out, you can expect the same speed from the 5.4K modes, and the 4K, which is oversampled from the 6K image. However, if you shoot 4K120, which does experience a 1.5x crop, your read time will speed up to 6.23ms. You just won't be oversampling from 6K. So yeah, this sensor is very, very fast. However, nothing is without compromises and in the case of the Nikon Z6 III, being that fast comes with some dynamic range drawbacks. So I've got those results to show you as well, but before that, let's test the mic jack on this camera so I can tell you about the sponsor of today's video, Storyblocks. Now, Nikon has improved the preamps on this camera over its predecessor and added a line level input option. So you can use a recorder like my Zoom F6 as your XLR inputs and patch that audio into your camera for easier post production, but my zoom can only do that at line level, so the camera needs to support that hotter signal, and the Z6 III handles this beautifully. Check, check, check. So here, listen to my boom mic routed into the camera while I tell you that Storyblocks is a stock media platform that offers unlimited downloads of diverse and high-quality content for one predictable subscription cost. No more expensive pay per clip pricing. Just pick a plan, pay that fee, and that's it. And you'll enjoy a library of over a million HD and 4K video files, images, and motion graphics templates. And speaking of those graphics, Storyblocks has expanded their library beyond just Premiere Pro and After Effects and now includes customizable DaVinci Resolve templates for motion graphics and animated sequences, an essential tool for creating professional-looking videos at scale. And it's always easy to find what you're looking for on Storyblocks because the platform is very intuitive and new content is commissioned frequently to ensure you'll have fresh assets to satisfy your project. So to get started with unlimited stock media downloads at one set price, head to storyblocks.com/undone or click the link in the description. Okay, dynamic range. So if you're new to dynamic range testing, what we do is we film a chart called the Xyla 21, which has a graduated scale of increasing intensities of light. And then we take that image and we run it through a program called Imatest, which gives us this result here. And along the top you can see what our test case was. In this case, this is the 6K on the 6K timeline and 24p N-Raw at ISO 800, which is the base ISO. And the reason why I specify the timeline is because it will let you know whether any oversampling took place. And in this case there was no oversampling, no noise reduction, just N-Raw 6K. And then over here at slope-based DR, we're gonna see the total amount of stops that imatest detected, which is 14 stops, which is decent. But then we go down to the 0.5 medium, which will give us a signal-to-noise ratio of two, which is a more acceptable clean stops, like the stops you would actually want to use. And in that case we get 9.89, so about 10. Now this is not a great result. So let's work with that image a little bit and see what a more realistic comparison would be if we were to compare it to say the H.265 that you could get inside of a Sony camera. So this next one is just what happens if you put it on a 4K timeline. So you do sort of oversampling yourself in post and we get a medium score of 10.6. This is still N-Raw and still no noise reduction. So now what happens if we were to apply some noise reduction because most cameras like my Sony cameras that have built in noise reduction, you can't turn it off. So we have to compare that fairly. So if we put a moderate amount of temporal noise reduction using DaVinci resolve, our score jumps way up to 12.5. This might be a bit aggressive and maybe a little bit more, but I compared it to what a noise reduced image looks like on other mirrorless cameras. And I get sort of a similar result. But maybe you could take a little bit off here to be conservative, but we can get over 12 stops by applying noise reduction in post to the raw image. If however you wanna do this internally, here I have the 5.4K H.265 image on a 4K timeline. So we're oversampling it, but H.265 by itself also kind of gets rid of noise a little bit just with the way that it compresses the image. And so we jump up to 11.6 and we get a 14.2 on the slope-based DR. And if we let the camera do that, so 4K on 4K, that means the camera oversampled it and we just took that 4K oversampled image and stuck it on a 4K timeline, still H.265, we get 11.7. This is good to know that the in camera oversampling or the post oversampling, is gonna get you about the same result. I still think that the Sonys outperform the Nikon a little bit in dynamic range even when trying to equalize everything. But again, I think they're using a better log curve than what we're working with with N-Log. So to test that, I also did a comparison. So again, this is our regular N-Raw using, developed as N-Log, and we get that 10 stops. If we do nothing else, so no noise reduction, no oversampling, we just develop it as V-Log, what you would get on a LUMIX camera, it jumps up half a stop to 10.4. So that just suggests that there's probably more to be gained by using a better log curve. Conservatively, though, I still think you're probably looking at a high 11, low 12 stop camera when speaking Sony language and all things being equal, but with a little extra room to improve with noise reduction. And that's one of the best things about having this N-Raw internal is that you can do all of that in post, which means that the ceiling for improving your image is much higher than it would be on a fully processed image coming off of a SD card on a Sony camera. Also, I did notice what appears to be a noise improvement at ISO 6,400 so perhaps that's this sensor's second native ISO. But if we look through the rest of the ISO range, we can see this camera performs quite well right up to ISO 25,600. It's not until ISO 51,200 that the noise becomes overwhelming. Color shifts are reasonably controlled as well. The worst offenders are ISO 5,000 just before the ISO 6,400 cleanup. And then again, when exceeding 25,600. The white balance tool on this camera is very accurate and gives you an adjustable target for precise selection, but I do wish it reported back the measured white balance after taking the reading. And overall color accuracy on this camera is great. In fact, Nikon often ranks at the top for color accuracy in my testing, especially their built-in flat profile. But for maximum dynamic range, N-Log is best. But I still have an issue with the official Nikon LUTs for N-Log. We're using the second version of the Nikon LUT on this camera similar to the Z8, but that still means that exposing is unnatural. The original N-Log LUT was good because if you exposed N-Log according to the white paper, you would get correct exposure after applying the LUT. The problem however, was the tonality was extremely harsh. The new version of the LUT has much smoother gradations in that gray scale, but also significantly brightens up the image, making exposing by the book a pointless endeavor. It might be time for Nikon to develop an N-Log2 and a new LUT that balances better exposure principles with the nice transitions they've established recently and possibly capture more dynamic range. Plus the addition of uploading user LUTS to the camera and having more flexible view assist options would be highly welcome. But regardless, even in its current state with a little tweaking in post, you're gonna be able to create terrific images with this camera. I also tested the battery life when shooting at 6K60 N-Raw, I got 101 minutes before the battery died. I didn't get any overheating warnings in this mode, but please keep in mind that my ambient temperatures are on the low side, so I can't make any claims about how this camera will perform in hotter environments, but it does seem quite reliable in a climate controlled setting. In 4K24 H.265, I got 2 hours and 21 minutes, which is a very respectable result. And again, no overheating in my studio. And then lastly, I tried the oversampled 4K60 and even connected a USB-C cable to the camera to test the power delivery. After about three hours, I did have a yellow temperature caution on the screen, but it never turned red or shut down. I kept it running for six hours total and then shut it down myself. The battery was still full. So the USB-C power delivery works quite well. When it comes to recording those codecs, the heavier ones will only work on the CFexpress slots, but the H.265 combos can be recorded to the SD card. However, even if you choose a codec that both slots support, there is no redundant recording option. I wish Nikon would consider adding backup recording to their cameras for the codecs that would allow it. You can use the HDMI output for backup though, as it provides a clean, high quality signal, and thankfully is using a full-size Type A port. One of the things I like most about it though, when compared to my Sonys, is that on the Nikon you can mirror the onscreen information and have it display on both the LCD screen on the back of the camera, and the HDMI simultaneously. You can also use the viewfinder in this way too, so you can be looking through the viewfinder and showing what you see on it over HDMI as well. Pretty cool function. The only limitations I found is that there's no way to enable the N-Log view assist over HDMI. And when you're recording N-Raw internally, the HDMI output seems to be limited to 1080p, but in other modes, you do get a proper 4K output. Oh, and speaking of that viewfinder, it's excellent. I believe this is the world's brightest EVF or something. It outputs 4,000 nits, which is an absolutely insane spec, and apparently it even supports DCI-P3 color gamut in case you know you wanted to edit your videos using your viewfinder. But no, the screens are great on this camera. The LCD is also the largest and highest res display in its class, and it's now fully articulating, which is appreciated. My only real complaint about this body, as you can hear, is that the strap triangles are of the noisy jangly variety. Stabilization is a mixed bag. If you're just trying to lock off some static handheld shots, it can do a pretty decent job. Certainly not the best I've ever seen, but probably enough for most standard focal lengths. However, for follow shots or anything with footsteps, it's not as compelling. You do have the option to enable the electronic VR, which at the cost of an added crop does improve this type of shot dramatically, but it still doesn't look as smooth as we've seen from competing brands. But autofocus on this camera is quite good. It inherits many aspects from its bigger siblings, has new algorithms, nine different detection modes, 3D Tracking, the works. In my testing for video, I was able to track a face down to about four stops underexposed and four stops over, which is great. Now, I was only using the 24-70, which isn't the fastest focusing lens for video for rapid movements, but the camera itself was quite sticky and felt very confident for talking head. Overall, I think this is a fantastic camera for the money, which I'm told is gonna be priced at $2,500 US dollars. If you consider what else is available in that price bracket, I think Nikon has a really compelling option with the Z6 III. They've definitely achieved many best-in-class titles with this body and have convincingly set the tone for what a 6K hybrid camera is capable of. Alright... I'm done.
