The Nikon Z6: The Best Full-Frame Mirrorless Camera (Except for One Thing)?

With Nikon’s shiny new Z6 hitting the shelves in a matter of weeks, Kai Wong puts it through its paces at a nearby zoo, testing its autofocus and all-round performance with the help of a seasoned, Nikon-shooting photojournalist.

Photographer Paul John Bayfield has been shooting Nikons in the field for several years, so he’s the perfect candidate to see how the Z6 compares to its DSLR counterparts, and discuss how it stacks up against the Z7.

As mentioned elsewhere, the autofocus system just doesn’t quite compare to the 3D tracking offered by the likes of the D850 and the D5. For Nikon enthusiasts, this was undoubtedly something of a disappointment. The new combination of contrast detect and phase detect systems implemented in the Z range seems to be in its infancy, and prior to the launch of the Z7, expectations were high thanks to the 3D tracking in Nikon’s DSLRs that had set the standard by which it would be compared.

For some, the autofocus performance is something of a disappointment, but perhaps it’s more acceptable in the Z6 given its lower price point. As Tony Northrup pointed out, Nikon probably oversold the Z7: "they promised me my D850 in a mirrorless form, and that was not my experience.”

With only three lenses available for Nikon’s new mirrorless cameras, and without any of them being put to the test by Kai and PJB, it’s hard to get a true sense of how the Z6 autofocus performs. In Kai’s experience, it’s not the quickest but still better than the Z7. Can fewer autofocus points really mean better decision-making?

For Kai, however, the autofocus does little to detract from the fact that, as an all-round consumer full-frame mirrorless camera, the Z6 could be the best option available. Shooting video comes with one small disclaimer: if you want to squeeze out 4K 10-bit 4:2:2 N-Log, you'll need an external recorder, and given that Nikon has been demonstrating models at launch shows with an Atmos Ninja V over the last couple of months, clearly it expects anyone wanting that level of quality to have no qualms about this.

We should get a better idea as more reviewers get their hands on more units, but until then, let’s give a huge shout out to Kai who somehow managed to spend 15 minutes discussing a new mirrorless camera without once becoming distracted by the number of card slots. Well done, sir.

Z6 should have been star of the Nikon show not the Z7.
Z6 is really good value for money.

Better ergo,EVF, LCD,menus , weather sealing than A7III but worse AF

Not sure why he didn't compare it with a native lens, unless he only had a body and adapter, but it's a safe bet AF will work better with the native lenses, although probably still no match for a D850.

I'm sure if the Sony was working with non-native lenses through an adapter, the Z6 would have blown it away, comparatively speaking.

revo nevo's picture

Sure but still with or without adapter A7 has eye AF that works much better

Still for me AF is not a big deal.

There was all that talk about Canon R but Z6 kills it for less money.

not even about money when it comes to EOS R ... Nikon just did better job this time

Tony Northrup's picture

We found native and non-native AF was about the same.

Damn. And here I thought I could get through a whole article about the Nikon Z without a mention of card slots.

Andy Day's picture

Argh. Sorry about that. 😬

Still can't understand why they left out a second SD card slot on the Z6 or the Z7. Really makes these mirrorless cameras unattractive for any sort of professional shooting.

Daniel Medley's picture

Oh, but don't worry. A second card slot is now a "distraction."

the reason nikon gave was, get this, they didnt want to make it bigger. hahaha
if that isnt the biggest poop Ive ever heard then I dont know what is.
how much space would an sd slot really take?
how hard would it really be for nikon, who makes very complex amazing gear to ask the engineers to add an sd slot without making it 3mm thicker?
im certain without a doubt that if they can make space proof amazing gear, that they could have added the sd slot, and im willing to bet my house that the next z6mk2 will have 2 sd slots and not come in thicker.
and if it does come in 3 mm thicker, thats even better, because I like decent sized cameras like the d750 which is a perfect compromise between super large and a7 tiny.

watch teardown of Z7 ... all the internal space seems to be fully utilized .. not shure how much bigger it would get but 2x thickness of a SD card at least if placed next to first slot

stupid excuse they gave Nate. a7III has 2 slots and its smaller. they could have done like in the d750 imo, they just threw the cameras out as fast as they can knowing the flaws it has. they put it out knowing it isnt what theyd like but its "good enough" and its true. the cameras have flaws and need polishing

they did it for many reasons. slow down sony, get the product to market for sales. recoup some r/d money, buy themselves time to make a better version 2

I think they designed the cameras a couple of years ago to target the a7 II and a7R II. Sony changed their design, but Nikon didn't have time. Clearly the camera not being big enough isn't a valid excuse; so many tiny cameras have two card slots, or they could have built in internal memory, or even a Micro SD backup card. Plus, literally nobody has complained that the Z cameras were too big, but many are complaining about the single card slot.

So, got a question... can they improve the focus issues via firmware updates? I personally couldn't care less about the slots, I'd prefer getting internal flash storage like we live in the 21st century (but that's another story), but getting back on point can firmware solve this or is this a wait for the next version for a fix?

I can't answer your question, but apparently it can be done (in Fuji XT-2's case). I remember a video about the Fuji XT-2 having a firmware upgrade, and it improved AF pretty substantially.

I got to do some hands on with the z6 and z7 recently. they were nice but need some improvements and more than 3 native lenses before I jump. I have been a Nikon user for years and love the 850, I also have the Sony A7RIII with the 28-70 f/2.8 GM lens. The current 3 Nikon Z lens line up just does not cut it.

(Except for One Thing) It's not the Canon R. 😂

Just shot 1300+ images at a high school basketball game with the Z6, FTZ adapter and 24-70mm f2.8, 70-200mm f2.8, 85mm f1.4, and 200mm f2 F-mount lenses, autofocus worked great. Oh yes also took 1K shots with a single EN-EL15b battery charge.

Shooting a lot or images (1k) on a short period of time (a 40-48 minutes school basketball game) won't make struggle the battery.

You're missing the point, time isn't the issue. But since you mentioned it, over 3 hours for both JV and varsity including warmups, player introductions and halftime show. Nikon specs rate the battery for 300 shots. I shot over 1300 images with a single battery charge.

So what's the likelihood of a firmware update being able to sort out things like adding 10bit video internally, and adding 3d tracking? Or do you think this is something they're probably saving for the revised version of the Z6? The card slots aren't a big deal for me, the media used however is. XQD is hellishly expensive in South Africa, and options are limited. It's a bit sad when all my other cards are SD, and probably the only thing putting me off getting this cam

Stephen I asked about this above, nobody is sure but Michael Higgins shared a great video above

Eric Salas's picture

No matter what, this camera doesn’t cut it for the price at the end of 2018 because at the end of 2017 there was a camera that smoked these new cameras in specs, performance, and at a lower price.

That’s the only reason everyone is still having this discussion; the better option still exists if you aren’t brand a loyalist.
