Nikon D850

This is why the Pentax 645Z DxOMark score of 101 was never published

If you dive into the comments on the recent news of the Nikon D850’s chart-topping DxOMark score of 100, you’ll notice a trend: people claiming that the Pentax 645Z actually scored 101 way back in 2015… before that score was unceremoniously scrubbed from the DxOMark website. So what’s going on here? Conspiracy? Foul play? Piles of money being passed around under corporate board room desks?

Not quite. The truth, as is so often the case, is a little less salacious.

A full review of the Pentax 645Z was never published, and that score of 101 only appeared online as part of a top cameras chart that showed up in DxOMark’s review of the Sony RX1R II sensor. The chart (below) showed Pentax on top with a score of 101, followed by the Sony A7R II with a score of 98. People asked about the score in the comments and were told a full review was “delayed” but “on its way,” yet that review never arrived. Later, the score was quietly removed and the chart was replaced.

Speaking to DxOMark earlier today, photography blog PetaPixel finally learned why DxOMark decided to pull that score: not for some nefarious reason, but because they never actually finished the review. Before they could publish, the company decided to pause medium format sensor reviews altogether.

“We made a pause on medium format a few years ago just because of our production bandwidth,” a DxOMark spokesperson told PetaPixel, explaining that they simply couldn’t keep up with the other tests they needed to do. “We will now soon republish this type of camera, and Pentax 645Z should be published soon […] in a matter of days.”

That last part is very exciting news. As medium → continue…

Nikon D850 in-depth autofocus test

We’ve spent some serious time assessing the autofocus system on the D850; from portraits to bicyclists, we’ve found out just how precise this camera’s focus is, and how well its subject tracking will keep up. Check it out for yourself in our updated First Impressions review.

The Nikon D850 is the best camera DxOMark has ever tested, first to hit score of 100

Forget all of those DxOMark Mobile scores, it’s time to talk about “real” cameras again. DxOMark just completed their review of the Nikon D850 and, not entirely surprising, it is officially the best camera DxOMark has ever tested. In fact, it’s the first camera ever to reach a score of 100, pushing the Sony a7R II into second place with its score of 98.

As it stands now, the camera rankings put the Nikon D850 and its predecessor, the D810, in the number 1 and 3 spots.

While the D850 isn’t the best camera DxO has tested across the board, it nevertheless put in top notch performance in every category. “The D850’s key strengths are its outstanding color and dynamic range at base ISO, where it again ranks as the number one among all commercially available cameras we’ve tested for these attributes,” explains DxOMark. If it falls even slightly short in any regard, it’s in the low-light ISO category where its higher resolution starts to sting.

That said, you can’t help but go wide-eyed reading DxOMark’s conclusion. As they say, this camera is “in a class of its own for image quality.”:

The introduction of the first BSI sensor in a full-frame Nikon DSLR with a super-high 45.7Mp resolution puts the Nikon D850’s image quality on par with, and often better than, medium-format cameras. The first DSLR to hit 100 points — rather apt for Nikon’s hundredth anniversary year — puts the Nikon D850 in a class of its own for image quality. At base ISO, it’s unrivaled for color in the DSLR class, and its headline dynamic range score is outstanding, too.

Nikon D850 vs everything

By Andrew Reid (EOSHD)

Comment on this article at the EOSHD Forum

Comment on the article Dinosaur or T-rex? The D850 is a dinosaur but thankfully not a ridiculous feathered one. If this is the way DSLRs go extinct then they can go extinct with their heads held high. The image quality in full frame 4K mode is truly incredible, the best I’ve yet seen from any DSLR since the Canon 1D C. I don’t know how it is even possible to do such a clean, detailed image from a 46MP sensor without a full pixel readout. Whatever the method, Nikon (or is it Sony) have delivered a real technical feat here. …

Not quite as good? Nikon D850 versus Nikon D5 subject tracking

Video: D850 versus D5 subject tracking

Photographer Matt Granger’s YouTube channel is chock-full of videos that run the gamut from fairly technical testing to fun challenges and prize giveaways. But we took particular notice when, last weekend, he pitted his new Nikon D850 against his Nikon D5 in terms of autofocus tracking. (What can we say; we’re nerds.)

But why even bother? After all, the D850 and D5 purportedly have the exact same autofocus hardware—performance should be virtually identical. In fact, in our conversations with Nikon, we were told that the D850 includes an additional processor to handle autofocus calculations, just like the D5; they also claimed this processor was omitted from the D500.

More importantly, we were told flat out to expect ‘D5 levels of performance’ from the D850.

So why is it that, during an early shoot with the D850, Granger said, “I felt like I was getting more [images] well-tracked with the D5 than I did with the D850.” Cue the tests in the video below:

Granger performed both low-light and daylight tests. In the former, his subject moved primarily in the X axis (read: across the frame); in the latter, his subject moved in all three dimensions. Both cameras were set to shoot at 7fps (the D850’s max), and shared all other settings as well.

In both instances, Granger concludes that the D850 is simply not as good at tracking moving subjects as the D5.

In the first low-light test, he notes some hesitation: the AF point occasionally lagged behind the subject before catching up (though at 3:00, where he says the D5 does not exhibit this behavior, it looks like the D5 also hesitates a bit, but perhaps not as severely).

Nikon D850 added to studio scene comparison

We’ve had some time to get to know the Nikon D850 and so far it’s safe to say we’ve been really impressed. Its low ISO dynamic range is class-leading, and it has proven so far to be a versatile tool for shooting everything from wedding receptions to white water rapid kayaking. We’ve also had a chance to put it in front of our standard studio test scene for your viewing pleasure – see how its 46 megapixels look side-by-side with its peers.
