Now that Nikon’s Z9 has launched into the mirrorless world, the biggest question is how it stacks up against the competition. And while it’s a seriously impressive camera, the same can be said about other cameras on the market today. Perhaps the biggest competitor to the Nikon Z9 is the Sony A1.
How do these two cameras compare? It’s a back-and-forth battle in many ways, and it might simply come down to whether you prefer Nikon or Sony as a system. But before I get ahead of myself, let’s take a look at the specifications of the Z9 versus the A1 and how they compare head to head.

As you can see, both of these cameras have truly remarkable specifications. They’re each capable of shooting rapid bursts of high-resolution images with a minimum of hundreds of shots before the buffer fills. My only warning against getting either of these cameras is that you’ll no longer have an excuse: If your photos don’t turn out well, it’s not because of the camera.
Between the two, the better choice isn’t immediately obvious. Sony has advantages in maximum frame rate (30 FPS raw rather than 20), high resolution sensor shift, and much smaller size/weight. Nikon has a bigger buffer, a lower base ISO, and a dual-axis tilting rear LCD. It’s also less expensive by $1000. (Nikon’s large buffer is only achievable in their new “high efficiency raw,” but Nikon claims it has “the same level of high image quality as the conventional uncompressed RAW,” so there’s no image quality penalty.)
Even at the same price, I’d say the decision – if you’re completely ambivalent about the brands – comes down to this: Do you want a big camera or a small camera?
The Sony A1 has a traditional mirrorless design, weighing 500 grams (1.1 pounds) less than the Nikon Z9 and taking up less than half the volume. In turn, it has a more cramped button layout, shorter battery life, and worse heat dissipation. By comparison, the Nikon Z9 is a hulking camera bigger than most DSLRs, but the layout with the integrated vertical grip is one that sports and wildlife professionals have gravitated toward for a reason.
The price difference obviously favors Nikon, but even then, I know plenty of photographers who would rule out a 3.0 lb mirrorless camera (or a 3.0 lb camera of any type) and it doesn’t matter that it’s less expensive than the Sony. So, start your decision with the camera size and weight in mind. Only after that should you start comparing the other features of the cameras.
For landscape photography and especially backcountry hiking, the Sony A1 is probably the way to go. In general, its sensor-shift mode and light weight are going to make a bigger difference than the Nikon Z9’s base ISO of 64 and dual-axis tilting LCD. The one issue is with extended shutter speeds (since Nikon goes up to 900 seconds), meaning that you’ll want to remember to bring along a remote release when shooting with the Sony after dark.
For sports and wildlife photography, I’d go with the Nikon Z9 even though the Sony has 30 FPS raw shooting rather than 20. First off, 20 FPS is more than enough for 99% of needs. Remember, 24 frames per second is video. The Z9’s nearly unlimited buffer is a bigger factor. On top of that, the Z9’s form factor and button layout are optimized for sports shooting, whereas you’ll probably want to spend more money to get the battery grip for the A1 if that’s your genre of photography.
Videographers should be happy either way. The two cameras both offer log video recording, 8K, 4K 120p, and 10-bit recording with 4:2:2 sampling. The biggest differences are that the Sony A1 shoots 240 FPS at 1080p (rather than 120 FPS), while the Nikon Z9 has a longer maximum recording time of 125 minutes and is capable of ProRes 422 HQ. Eventually, Nikon has said they’ll release a firmware update with 12-bit raw video recorded internally (including ProRes raw if shooting 4K), which may push it over the edge.
In terms of broader considerations, Sony has the larger lens lineup at the moment, although Nikon is swiftly catching up in the supertelephoto department with their 400mm f/2.8, 400mm f/4.5, and 800mm f/6.3, among others. Nikon also has plenty of F-mount gear available from years of making SLR and DSLR lenses, and supertelephotos are some of the lenses that work best on Nikon Z cameras with the FTZ adapter. So, even though the size of the lens lineup favors Sony, it may not matter to the Z9’s target audience.
Overall, both of these cameras are amazing and at the peak of what a modern mirrorless camera can do. Rather than saying, “You can’t go wrong either way,” I’ll say this instead: “You will go right either way.”
Take a long look at the specifications above, and don’t forget the form factors of the two cameras. Then, once you’ve filled your wall with charts and strings like in a detective movie, feel free to flip a coin :)
Please explain z8 vs sony A1
As a wildlife photographer, I just cannot imagine lugging that Z9 around in wild environments when I am carrying all of my camera equipment on my back. The features between the two are very close. I shoot with Sony and I have some dislikes for sure, but I would really hate having to carry around that mammoth camera unless i was being driven to where the wildlife was located.
The summary above says the Z9 viewfinder refresh rate is 60 Hz. Firmware (2.0, I think) added a 120 Hz refresh rate as an option. You might want to correct the summary.
Just fixed it, thank you!
I had a D850 and a D500. I replaced them with the a7riv and a7iv. With all the hype over focus abilities, I was really disappointed in many situations how they both got confused where I don’t remember the D850 would have been. Also the EVF drives me nuts. The drop in resolution at focus, the jelly look, the focus peaking completely obscures a small point of focus and then there is the lag on start up. I’ve heard/read that the Z9 is really the best EVF experience? I don’t to be hoping and guessing that the EVF is accurate.
I am just more than happy that I was patient, staying with Nikon and not looking around and loosing tons of money switching to any other brand.
Looking at around 30k of Nikon glass (plus 20k of Leica M glass), the Z9 (arriving tomorrow) is the perfect next step after D700, D800 and D4 for me.
It gives me all the options plus in camera 8K60p proRes video, GPS, auto pic uploading etc.
2x CFexpress cards (1 TB), SmallRig L-bracket and Rode mics are already sitting here waiting and I can use all the D4 batteries as well. THANKS Nikon!
I love my Sony A1. IMO it’s the Holy grail of cameras. I myself am an introvert. TBH I’ve always wanted to shoot Nikon but when I was younger I started out with a Minolta. Later on I picked up a Canon 3xi. I was going to get a nikon but my brother got one and I didn’t like him very much so I got a Canon instead lol. Now that being so outdated I wanted something better so I got a sony a6400 cuz of the autofocus and being so compact. When I heard the a6600 was coming out I canceled my order for the a6400 and bought the a6600. I loved it but I wanted something full frame so I returned that one and got the a7iii. I noticed the af wasn’t as good so then I got the a7riv. I thought that camera was amazing. I didn’t like the blackout and a couple other things were bothering me about it. So when the Sony a1 came out I jumped on that one and never looked back. I love how you can shoot in crop mode. Gives you pixel options. Hi res for cropping which I do alot. No black out. Super fast and accurate af. All in a compact body. When your going hiking shooting wildlife those lenses are big enough, you don’t need to carry around a brick of a camera. Too heavy. Love all the custom buttons on it. It’s just an all around amazing piece of tech. I also like the third-party options for lenses. My a1 and my tamron 150-600 is amazing for wild life. My all around every day lens is the Tamron 35-150. Amazing combo. Sure it’s an f2.8 but you can always brighten things up in post if needed. I have a few more lenses aswell like my Sigma 105 macro
All that and Capture 1 I think is absolutely perfect for my needs. Sure there are some other cameras that may have some better features but they are so close at this point it’s basically nitpicking. I do like some of the features on the Nikon z9 but not enough to switch out everything. Again that thing is stupid heavy. Well I could go on but I think I’ll stop here lol

Sadly, the Nikon cameras do not have the excellent bird eye tracking function of the Sony A1.
I use a Nikon z7, and even with firmware updates, the Nikon falls way short on its tracking focus ability on moving subjects.
My beau’s Sony A1 eye tracking feature produces tack-sharp eye focus on birds in flight consistently.
If you’ll recall, this is a comparison between the Z9 and the A1. The Z9 and Z7 aren’t even remotely comparable when it comes to AF performance.
I have a problem: I use Nikon Z9 with NIKKOR Z 100-400MM F/4.5-5.6 VR S lens. Firmware C 2.00 LF 1.10. Custom settings: a1 AF-C Focus; a6 AF activation Off(with out-of-focus release disabled). The shutter release priority is set at Focus. When the lens is set at 400 mm, the AF-ON and Shutter are pressed concurrently. The camera won’t fire. But when the lens is set at 100 mm, the camera can fire. Please try with yours and see if you have the same problem. If you do have the same problem, please explain?
Hi Foo. I have had an issue with the same settings a1 af-c set to focus and even if a6 is set to enable or release in version 1.11 shutter would not fire if aperture was above 5.6 (say f6.3/f7 etc). In version 2.0 firmware shutter would fire if above f5.6 but slower and in spurts getting around 10 frames per second in 20 frames per second mode (which is better than zero with firmware 1.11)but still not 20fps. What I discovered is this does not occur if A1 is set to release or focus/release. I would check to see if at 100mm your aperture may well be below f5.6 (say f4.5) and when you get to 400mm what is your aperture ? I’m not sure if this is a fault or the way the aperture changing to f5.6 to see the image and then going to say f7 it needs time – but its always in spurts and not smooth. You have to be focusing whilst shooting for the problem to show up and even on stationary subjects and has to be in af/c not af/s. If you can check and see if you have similar results or if someone else has had similar results let us know as I dont know if camera is faulty.
I disagree that the Z9’s integrated vertical grip makes it preferable for wildlife. With the Sony, you can use a battery grip if you’re shooting off a tripod or from a fixed position, but you can take that battery grip off if you’re going to take it on a hike. With the Z9, you’re stuck with the heavier weight and larger size. Plus, Nikon has very few dedicated Z telephoto lenses and the ones they do have are insanely backordered.
