About me:

I admire the paintings of Goya, El Greco, Rembrandt, Gauguin, Courbet, Picasso, Salvador Dali… If only we photographers could create images as compelling as the masterpieces of them…

My present light-painting tools are: Nikon D700, AF Nikkor 35mm f/2D, Nikon D610, AF-S Nikkor 24-85mm F3.5-4.5G ED VR, AF-S NIKKOR 35mm f/1.8G ED, AF Nikkor 24mm f/2.8D, Panasonic GF-1, Panasonic Lumix G 20mm F1.7 ASPH, Nikon Coolpix A, Panasonic Lumix DMC-LX3, Canon PowerShot S110 and my SLR heritages. Recently I've added Ricoh GRD2 to my arsenal.

James Bligh: (Quote) The other consequence of the smaller photo-sites might be a slightly stronger effect from diffraction. While the optimal aperture on the D810 (and D800) was f/7.1 it could now be f6.3. Stopping down beyond this could make images softer due to diffraction. (Unquote)

Even if we get mirrorless FF and are free from focusing error of DSLR, high pixel density sensors are far into the realm of diffraction softening. So I think it is appropriate to think about what the ideal pixel count in a given sized sensor is, in other word what pixel count is the sweet spot in FF or APS-C sized sensor.

BTW there is a report which says resolution seems to be almost same between D850 and D800/D810 despite an increase of 10 megapixels.

(Quote) Compared to the D810 there may not be as big a difference as you’d think – The increase in linear resolution is only 13% (Unquote)

James Bligh: What was an issue 5 years ago may be a reminiscence but I am afraid people are too forgetful. Or may I say blindfolded?

If my memory serves me correct, no one in dpreview staffs or not a one article among more than dozen ones dpreview has published so far has mentioned about diffraction in D850.

Well, you may read the following dpreview article.

https://www.dpreview.com/reviews/nikon-d800-d800e/25

Has diffraction suddenly not become an issue in 45 MP FF sensor when it was an issue in a 36 MP FF sensor? Human memories may be strange things but physics stays, doesn't it?

@J A C S You may use F16 F22 in D850 but I will never use them in D850. I may use F8 but I am not sure I will dare to use F11 in D850.

@J A C S You may agree that the consequence of high pixel density is very narrow range of usable ISOs in compact digicam and I am afraid it will be very narrow range of usable F stops in DSLR.

@J A C S What you are saying can be summarized to two words, that is diminishing return. If you recall the evolution of compact digicams everlasting increase in MP was stopped or reversed albeit temporarily by 6 MP Fujifilm F30 and I think/hope the same phenomenon will emerge in DSLR in near future. Fact is the public in general may be ignorant but not everyone is.

@J A C S So be it but I wonder no I am afraid DSLR has become/is becoming more or less like compact digicams in regard to usable F stops, it is a pity.

@J A C S Because Amadou Diallo, Barney Britton and Richard Butler say so.

(Quote) Look carefully enough and you can probably see a subtle difference in sharpness between the images shot at f/4 and f/5.6 compared to the one at f/8. By f/11, the effects of lens diffraction start to become more pronounced and at f/16 and f/22, a noticeable amount of sharpness is lost (Unquote)

@Androole It just won't necessarily lead to more resolution if you are heavily stopped down.

-- I may rephrase it as follows.

It leads to deterioration in resolution if you are heavily stopped down.

There are almost no practical disadvantages to higher MP bodies, especially when BSI sensors are used.

SRHEdD: Language is our friend. It doesn't say "...only DSLR you'll ever need." It specifically says, it COULD be, which allows for the fact that it couldn't, wouldn't or won't be as well. You choose. There are far too many sheep here who leave out words to make their point. The article is a general piece about overall capability, perfectly fine by me. I've seen and read other articles on here about other cameras that are highly capable, one article alone didn't make me blindly go buy the product. Only the sheep do that. The rest of us read it (or not) and add the information to our internal reference (or not).

one article alone didn't make me blindly go buy the product.
-- I may inform you dpreview has published more than dozen articles about D850 so far.

Only the sheep do that.
-- I guess you are an wolf. BTW I choose to be a cat.^^

(Quote) In my mind the A7Rii earned its gush quotient from the brain trust at DPR because it set so many goal posts for future cameras to match. What disturbs me is the manipulative re-writing of camera history represented by the loose fact journalism (an untested device) surrounding the D850 introduction. It seems driven by a sense of relief that Nikon hasn't totally dropped the ball in the high end camera game and is still able to successfully iterate off a camera that was launched three plus years ago. This must mean continued ad revenue, continued clicks and something new to write about. But it's hardly the breakthrough product it's being made out to be.

Don't blame Nikon for overselling expectations. The fault lies solely with the round-the-clock hyping of the product by the industry media, with most of the blame trackable to one source. (Unquote)

But really, the impact on our work flow has been that bigger files, which added nothing to the overall quality of a project, cost more to shoot, took more time to process and cost more to archive. We ended up taking more time and doing more work without any increase in overall quality (or profit) within our prevailing use targets. Our envelope for clients didn't go from a #10 to an A4. Just an increase in the hassle of handling much bigger 14 bit Godzilla sized files. (Unquote)

(Quote) Up until we hit 16 megapixels there were always some (few) situations for advertising photographers where more sheer resolution was needed. Once we hit the 24 megapixel mark we could have stopped cold and only 1% of the jobs we handled would have been perceptively impacted. Not made un-doable; just somewhat impacted. When we exceeded that threshold we came face-to-face with mostly diminishing returns. Yes, the BSI sensor in the A7Rii has great image quality but what if Sony had concentrated on bigger but fewer photo sites? Would the files have been even better?

In reply to:

AdrianPocea: Has any of the reviewers actually TESTED this camera in real world? I mean, I had the 5ds, I know what is like to handle almost 50mpx. Where are all the problems of this resolution gone? Wasn't like impossible too get sharp pictures south of shutters of 250 ? Where is the reduced mirror vibration, the reinforced bottom of the camera? Where is the diffraction limit, that kicks in around 5.6 and creeps in at 7.1, making this camera pointless for studio product and macro work, where you need very large depth of field? How can this camera , at almost 50mpx, can have a double iso performance compared to D5, a camera designed for sports an d low light , with less than half of the mpx ? Unless Nikon discovered some miracle water formula from some Harry Potter movie I really don't get how they could have defied the laws of physics. I am waiting for the camera and real world reviews. What I had seen until now, very little, is not convincing for me.

@AdrianPocea Hand blur, diffraction... these are all valid questions, especially the latter should be thoroughly investigated. Thank you for raising sound doubts.

@sh00t3r I understand your dire situation. I suspect D500 is a better choice for your purpose since D500 has viewfinder magnification of 1x when that of D850 is 0.75x and the pixel count of D500 is almost the same as that of DX mode in D850. Anyway good luck wildlife shooters!

@maljo If you find yourself cropping regularly you'd better study Bresson and/or visit an art museum and learn the skills of masters. For example I may suggest you to study the picture The Crucifixion of Saint Peter, 1601 by Caravaggio. Do you think he cropped the picture?
