On article These are the best cameras you can buy right now (479 comments in total)

Strange D500, very highly rated at DPR and considered the best under FF camera money can buy, is not listed. D850 and new Sony FF ml deserve the billing, bit some other cameras here look out of place.

On article Top 10 sample galleries of the year #1: the Nikon D850 (147 comments in total)

Reading the brand-loyals’ bitter comments below is very embarassing for humankind.

Anyway, a decent year in gear, despite all doomsday mood that has prevailed among DPR readers and fora members. Next year should be also interesting, as C/N will likely release their new ML lines.

Cheers.

Burnt to a Crisp: Great to see Sony putting Nikon to shame! And off-tripod, Sony's formidable IBIS should make the difference even greater.

Canon isn't even in the running...

I don't know where these brand fans see these differences. Well, that what's DPR is about ...

Eric Hensel: If you just look at RAW high-ISO noise patterns -they are much sharper with the Nikon.
Baked in sharpening?

Cameras' files respond differently to same sharpening settings and profiles. But I agree the D850's raw conversions look a bit oversharpened.

These camera are so close as to make IQ not an issue regarding choices. Body abilities, functions, how they will be used, and lenses available will be much more relevant to determine which is best for you. Pixelpeeping is not a good way to judge these cameras. (Still, some seem to see "huge" differences. Maybe in the eyes of beholders.)

Really? To me, in RAW, the Sony and D850 look the same at 6400 and 12800, the highest I'd dare to go. Jpegs are not a good basis for comparisons, since, if you are going to do NR, dedicated softwares do better than in-camera.

Mark9473: Rishi, I'm a bit disappointed at how you over-hyped this feature in your writing compared to the actual improvement in image quality. Sure there's a small improvement, but unless one is using a huge screen to pixel-peep these images there's little practical benefit that I can see.

@BBQue: incorrect. If you print with good quality printer at wall hanging sizes, you make use of more pixels, only you don’t look at it from a few inches away.

Agreed, Mark, this is at a level that only 100% on a low res monitor looked from 1ft away is noticeable. And only applicable to static subject, not for real landscapes. Hype in purest form

Link | Posted on Nov 12, 2017 at 23:48 UTC

Interesting, but comparing it to D850 shows very little difference, unlikely to be seen on prints. One issue with ACR and D850 are jaggies, that introduce issues in various parts of image. The Sony is cleaner in that respect, not sure if from pixel shift or conversion.

An Omega Seamaster took a quick dive and never recovered. A Casio G-Shock sobrd to -20m various times and is still working. Difference between water res and water proof. But D7000 was taken to Lake District where it rained most of tge time, had to clean front lens for every shot and it’s still working years after that, so cameras may be used in wet condition, but salt w is another story.

Well, you may list sme, starting with Canon, Apple, Microsoft, alll major car makers, etc. This post is actually pretty offensive, but, alas, this is Trump era we are in, no elegance or respect for those not in one’s own identity group.

Well, despite some absurdly uninformed posts below, as a Nikon user in Brazil, I think this is said, period. There are thousands of pros, especially wedding and local photojournalists, who use Nikon equipment here. For a company that sees itself, as I thought Nikon saw itself, as a major global player in photography, and a major pro-market player, this is not conceivable. The main part is the servicing/support, as people may buy their gear in other countries o via e-commerce (B/H). Brazil's economic outlook is currently bad, but there are already signs of recovery, and it's still one of the largest markets for any product. So, to me, this talks more about Nikon's current situation, they are saying they are so weak they can't afford to wait for the market to recover, that they need to restructure heavily, by closing plants and important markets' operations. Time to rethink future purchases.

Blame it on the smartphones and forget about the whole 1 series mirrorless strategy debacle.

Typical corporate cop out...

Eles chegaram a vender mais de 13 milhões de compactas, esse mercado evaporou. Nada a ver com mirrorless.

I wonder if people that write here about camera markets know anything about them. Some talk about how well the premium models are doing well, how NIkon is a dinosaur, etc. Well, Nikon is second only to Canon in compacts. But that market is shrinking, as Canon has reported. Their sales dropped from like 20 million compacts to less than 5 million in just a few years. Nikon's performance is similar. The drop is in the low price models, one just has to check the launches of new models here at DPR in the past few years. That won't come back, so the overall camera production will never go back to what it was 3 years ago. Good move, close a plant and relocate resources. All makers will be doing this in different ways, Panny has consolidated their electronics divisions, and others will follow, Nikon just did what it needed to do now.

Jefftan: if one day Nikon bankrupt it is the fault of incompetent management

compact camera dead?
Olympus seem to be doing well on TG-5
Sony seem to be doing well on RX100 series (1 inch also compact)

except the old dinosaur DSLR with lock in buyers because of lens
Nikon don't seem to know how to make any interesting camera

Nikon sells more compacts than either Sony, Olympus or Panny. Only Canon sells more. But the sub USD200 market is gone, and other areas are stagnant, at best. Better to close a plant than see it drain resources.

In reply to:

aftab: Interesting to read Canon's Q3 report in this respect. Canon has reported 13% increase in compact camera sale in 2017 compared to Q3 2016; "As for the compact camera market, which continues to recover from the earthquake, we posted
strong sales of such premium models as the G9X Mark II .....our unit sales in the third quarter of this year showed an increase of 13% to 850 thousand." Despite this Canon admits that overall compact camera market has been shrinking and their total sale will be down by 1% this year; "For compact cameras, as we are exceeding our expectations mainly with G-series models, we raised our projection and now expect our sales to be down 1% to 4 million units." So, it appears that people are still buying 'premium' or 'high value' compacts and Canon has found a way to make profit selling compact cameras (they are projecting 4.8% increased profit this year). They didn't give up as Nikon seems to have. Does Nikon think that it is better to quit sooner than later?

Yes, "premium models". They used to sell over 15 million compacts just 3 years ago, now it's more like 4 million. The news is about entry-level camera market, that was the large volume part, it's gone, and won't come back. Not a bad thing by the way, makers just need to concentrate on the USD500+ market, and produce great cameras. They'll sell, just not like the old USD100-200 models, that's what the smartphone killed, as predicted.

In reply to:

Osa25: The problem is not rise of smartphones but rather failure of camera makers to improve image quality and features of "compact cameras" , a term which is in fact a euphemism for C-grade camera.

People miss it entirely. You have a smartphone. You carry it all the time. It works as phone, as internet browser, as social media connecting device. And it takes decent pictures and video that are easily sent via social networks, whatsapp, etc. Why would one carry another piece of gear that only dow 10% of what the smartphone, at about same quality level (improve one, improve the other)? The cheap camera only device is done with, never to come back. Camera makers must concentrate on providing gear for the part of the population that care for something more, it's always there, potentially, say, 10% of the population? That's a lot of people, so a lot of cameras to sell.

UllerellU: What a poor excuse ... My phone does not do anything that my RX100 does not, but my RX100 does a lot of things that my cell phone does not do. Starting with the High ISO Resistance, the Optical Zoom range, the dynamic range ...

Yes, maybe one day the mobiles arrive at this, I do not know, but even if they technically arrived at this, they would still be missing the hand controls, personalized FN buttons, control dials, manual focus rings ...

I do not know why mobile phones are being discussed, mobile phones are for those 95% who do not like photography.

And I compare a mobile with my camera to always carry over, but it is that if I have to compare it with my FZ1000 or with my interchangeable lens system, turn off and let's go ..

Read again: entry-level compact cameras. Absolutely true, just go to the Cameras database here and checl the number of compact cameras launched by Canon, Nikon, Olympus, Sony and Panasonic in the past 5 years. The decline of new models is amazing in the group of cheaper compacts, only some special cases remain, like water-proof models and a few others. The survivors are the super-zooms and the larger sensored models, like the RX100.

aris14: I think that the 3 years old Pana LX 100 should be in a vlogger's short list.

I agree, the LX100 is a very nice compact, with better IQ than the Sony. Why is the AF lacking? We will likely see a successor soon, and it should be even better, but as is, it's a great travel camera which I use more often than the dslr.

Unrelated to IQ per se, some shots here look like they were done by someone who has absolutely no knowledge about basic framing and composition concepts, or even good exposure technique. Someone getting a D850 would do a better job, for sure.

People keep talking about the demise of dedicated photo equipment, but forget that before the advent of digital tech, slrs sold in the thousands, they are still selling in the millions, despite some slowing in recent years. Add mirrorless systems and figures are pretty healthy, actually. Just a footnote: Nikon sold about 150,000 rangefinder bodies along 15 years, now they sell more than that in a couple of weeks, Canon sells more. So, like the rumor that Mark Twain had died during a stay in London, the news of ILCs demise is an exaggeration.

A remark: the first phrase of the piece is poorly written, just remove "today" from the end, or the whole phrase and start with "Canon has announced that two milestones have been hit, 90 ...
