In reply to:

Boss of Sony: The important question is: does the lens require massive software-based distortion correction at wide angles,resulting in soft edges like the Panasonic LX100 does?

Distortion correction? Almost certainly, given how small it is and the fact it offers a 24mm equivalent wide angle (also, Canon's wide-angle compacts have worked this way [for many years now](https://www.dpreview.com/articles/5653763779/a-distorted-view-in-camera-distortion-correction)).

I wouldn't try to predict the degree to which this will be visible, though.

In reply to:

Boss of Sony: I believe this is the first compact camera with a fixed zoom lens and an APS-C sized sensor. Is that correct?

No. For reasons given on the other story.

(Sony R1, Leica X Vario and, arguably, the Ricoh GXR A16 24-85mm).

Ironically, given your username, you'd be wrong.

[Sony R1](https://www.dpreview.com/products/sony/compacts/sony_dscr1) and [Leica X Vario](https://www.dpreview.com/products/leica/compacts/leica_xvario) predate it, at the very least.

And, depending on how you look at it, perhaps even the [Ricoh GXR A16 24-85mm module](https://www.dpreview.com/products/ricoh/slrs/ricoh_gxra16_24-85).

CameraTolerantGuy: What' the reason to buy this instead of the a6000 + 10-60 PZ?
F2.8 vs. 3.5 and a touchscreen?
Yay.

Front and rear dials?

Weather sealing?

1/2000th flash sync?

Dependable video AF?

Built-in ND for video?

I'm not saying you should make the choice one way or the other, but this is a much smaller (and more expensive) camera, that offers something rather different from the a6000.

In reply to:

Gordonium: I thought the competition suppose to be Eos M5 with kit lens?

There's not much to say, vs the M5. The M5 takes interchangeable lenses and has a bigger battery, the G1 X III is weather sealed and has a leaf shutter.

I guess I assumed that anyone wanting a fixed lens camera would probably be more interested in looking across brands, rather than staying in-brand and considering ILCs.

MannyV: In Canon official video, the aperture at wide end is 2.8.

Yeah, sorry. The "F3.5" was a typo but the equivalent figures are correct.

Not to mention that the problem was solved by Leica with the R9 as others have already mentioned.
The universe loves you Richard, please try to love it back.

I'm not downplaying the importance of Leica as a company but, given how many Nikon F and FE series, Contaxs, Olympus OMs, Minoltas... exist, the number of people for whom a Leica R8 or 9 is 'their camera' is a tiny, tiny percentage.

I've modified the text to make clearer that I'm writing about retrofit modules, not designed-in-parallel units for modular cameras. I didn't forget or overlook the Leica R (I wrote DPR's news story when the series was abandoned, so I do remember them), I wrote something to which they're not relevant (though I agree I should have made that slightly clearer to start with).

XoverCameras: "(Despite my sarcasm at the impracticality, it's an impressive bit if handiwork)"
Thanks Richard, I appreciate the compliment. It was a great fun project and my only aim was to put to rest all the naysayers in forums and the like, who were declaring that an SLR could not be be digital as well. I proved that it can be done and by a non technical person. Far from being a useless exercise, I have a collection of Nikon FA, FE & FE2 SLR's and my digital back fits them all. It's great for testing these for shutter speeds and light meterage and for checking my old legend lenses. Did you also know that it shoots in normal RGB colour as well as infrared? Show me your DSLR that does that! With the expertise of an electronics engineer the shutters could be easily synchronised but even better would be a software hacker who could delete the need for the Sony shutter all together.
All the best and enjoy your expensive DSLR's. I'm sticking with film as it's loads more fun.
Robin.

I'm glad I didn't seem too dismissive.

I'm hugely impressed that you got it working and by the level of commitment and precision needed to get there. I can't imagine myself even successfully following your instructions, let alone overcoming all the technical hurdles along the way. So, while I don't think it's practical for most people to copy, I didn't want to dismiss what you've achieved.

Photo graphic: Looks like someone was "born yesterday".

Even though they were near finished with their review, they "paused" reviews (just after realizing the score would be their highest) of better cameras (wasting the work they had done) because they were "too busy".

But don't worry, the check is in the mail and the 645Z after all this time will eventually be reviewed!

Isn't that exactly what Occam's Razor is for? Where you have insufficient evidence, assume that the simplest explanation is correct?

To be clear, I have no additional insight into the workings of DxO than you guys do, but I do know what it's like trying to get hold of a 645Z from Ricoh.

SmilerGrogan - not impossible, just highly improbable. And the difference between what some people are hoping for (and I'm saying is very unlikely) is a retrofit module, not a back for a camera designed to be modular.

It's a quick, lighthearted piece, so I haven't tried to make it as technically watertight as I would for a more in-depth article. I figured that most people would be willing to accept the Leica R8 and R9 are obscure edge cases to an article about "dust[ing] off your beloved Nikon F-something."

In reply to:

fsahouri: could be a stupid question, but what if the issue is in both d5 and d850 but you can only see it because of the high resolution of the d850?

It's a reasonable question but no, the difference isn't just one of being able to see the mis-focus in more detail. The D5 stays on the subject, whereas the D850 sometimes loses the subject completely.

It is peculiar, I agree.

In reply to:

jdc562: Regarding autofocus, this is not much of a test--easy-peasy for just about any run-of-the-mill camera. It's not too hi-tech to distinguish a close subject from a distant background. A better, and more relevant, set of tests would have more high-contrast and well lit elements nearer the subject.

And yet most cameras are terrible at it.

The idea behind the test is to first test the camera's ability to judge a changing subject distance, predict its speed and drive the lens suitably quickly. Most PDAF cameras can do this, CDAF cameras tend to struggle.

Then we add the extra layer of complication of expecting the camera to recognize and track the subject. The weave also adds more variation to the approach speed. Between these two changes, most modern cameras only perform moderately well at this.

Essentially this simulates, with a good degree of repeatability, a semi fast subject moving in a way that is unpredictable to the camera (eg a child running around).

For sports cameras we then take it a stage further by going out and shooting sports (with similarly coloured targets and objects crossing at different depths). We'll be doing this with a D850 and grip in the coming days.

Livio Spallone: I could be wrong but 3d tracking is about keeping track of the movement of a low resolution shape and color part of the subject. In the failed test the face of the subject goes close to the wall : same colors. Would like to see a d5 tracking the face in the same condition : subject and background of the same color.

That's the point. While it's a bit disappointing that the claims of 'D5 level' AF performance appear not to be true, the D850 is generally very good, relative to its other high pixel count peers.

Carey shot the D850 side-by-side with the D5. The D5 doesn't make the same mistakes.

In reply to:

Robin Ducker: I have said it before and I say again, test again with the battery grip and high power battery. I think the results will be better. All of the D850's autofocus electronics should then be on a par with the D5 with less latency and more drive for the focus motors.

We have already started testing with the battery grip (the full results of which will be a separate article about shooting sports). We saw nothing to suggest it fixed the things we encountered.

Matsu: I'm afraid Richard reaches the right conclusion, but for the wrong reasons. All the problems were already solved over ten years ago, it's in DPR archive too:

https://www.dpreview.com/articles/4888226123/leicadigitalr9

The real reason is cost. To engineer a digital back and manufacture it for sale, is basically to create a product with the same cost overhead as a camera, only one that must then be attached to an old camera that isn't really that great compared to a modern digital camera.

I have an old Nikon FE I'll never sell. It's value is purely sentimental. I've not run film through it in years. I'd even spend $500-1000 on a digital back for it, if only for my hands to remember my dad's first photography lessons to me in way that seemed purposeful and not purely nostalgic. But how many people would do that? Maybe at $200-300 ??? Manufacturers know the real market is small and low margin. That's why we've not seen it.

In fairness, cost was one of the issues I highlighted, both in this article and at more length in the 2012 and 2013 articles I linked back to.

Ebrahim Saadawi: Who holds the Patent for Dual Pixel Auto focus technology? Canon seem to brag they invented and pioneered this technology in the 70D.

If Samsung can use it, it's either commissioned by Canon to do so or it's not a patented technology, in which case one would wonder, with the marvel advances that comes with Canon DPAF then why Sony and Nikon cameras don't have it too?

It all depends on what 'Sony-sourced chips' means.

If Samsung has simply commissioned Sony to manufacture the chips, then they could use the same IP we're seeing here: Sony wouldn't have the right to then use that design for itself or other clients.

Scottelly: "Timelapse recording Yes (4K or 8K movies)"

Really? I don't think you can get an 8K movie out of a D850. The camera DOES NOT HAVE THAT FEATURE. Sure, you can make 8K movies with photos from a D850, just as you can make 8K movies with photos from a Canon 5 Ds or a Sony A7r II or ANY 24 MP camera (by scaling the photos up a little bit). But none of the cameras, including the Nikon D850, can produce an 8K resolution video that you can watch on an 8K TV. You have to make such videos with a computer.

Why do you insist on spreading Nikon's lie?

Scottelly was highlighting that the way our specs were reported were misrepresenting the situation. I've subsequently amended our database to avoid this misrepresentation.

Personally, I think Nikon branding of timelapse as '8K' is misleading, since it implies video.
