More mpix does not automatically mean more resolution.

Maybe he leaves it out because the D800 costs less than the 5DMKIII
I leave it out because it is a non sequitur .

Sweet spot? I thought it was 12mp? Oh, that was so a couple of years ago. You really think Nikon (and Canon) aren't putting a high MP sensor in their pro bodies? You're going to look pretty silly when it rolls out. There's going to be some form of a D4x, just wait for it. Why would Nikon sell a body at 3K to pros if they can guilt them into buying a 9K body instead. They did it before, they'll do it again. Not all praise for Nikon, but it is what it is. That being said, everything else in the original post is pretty much garbage. Smearing? Really? I guess we should go back to 1mp cameras so we can shoot really slow shutter speeds.

Chiron.... thank you for removing any shred of doubt I continued to harbor that you were not a severely misinformed and a mindless fanboy. You make VivaLasVegas, Taikonaut, etc look positively sane. Congrats!
 
More mpix does not automatically translate into more resolution under all levels of mpix, all lenses, all ISOs, and under all shooting conditions. There is a law of diminishing returns that operates, and the question is what level of mpix is optimal for your use. This why the pro models of Canon and Nikon do NOT feature the highest levels of mpix. More mpix automatically equals more resolution only on a laboratory test-bench, not in real life.

Using a camera on a tripod, with the mirror locked up, with self-timer release, with live view magnification, with the best possible lens at its best aperture, with a high shutter speed, at low ISO will yield more resolution per mpix. But the same camera used at a wedding or to shoot any kind of live event will not get you more mpix and may well cause you to lose shots because of things like increased motion blur from subject or hand movement, and the need for higher shutter speeds.

Similarly, even the best lens used at it maximum or near-maximum aperture will not produce higher resolution because the lens at a wider aperture cannot resolve the level of detail that the sensor can record.

Similarly if you are using a small aperture with the best lens because diffraction will limit resolution.

Similarly if you are using higher ISOs, because the increased need for noise reduction will smear the higher resolution and smaller and more numerous mpix produce more noise requiring more noise reduction.

In such situations, the 5d3 will usually produce more actual resolution in the final image and much more photographic flexibility in getting the image you want in the first place.

This is why Henri Cartier-Bresson started to use 35mm in the first place--because of the kinds of situations he wanted to shoot in: The constraints and technical practices necessary to get larger-format quality destroyed the ability to get the image in the first place.

This is what DPR's review of the d800 points out when it writes and repeatedly emphasizes that "inordinate lengths" are required to actually get the increased resolution that the d800's mpix are capable of. Many other reviews have made the same points. Luminous Landscape even recommends a focusing loupe, presumably because the live view focusing magnification on the d800 is unusable.

And this is why pro models costing twice as much as the d800 do not feature the d800's levels of mpix--because they make the camera less flexible and usable for making most images.

Nikon did not put the 36 hex on their pro models, but used it to aim at amateurs/prosumers who would be more taken with a big mpix count without really understanding what it means in practice. This is what DPR was repeatedly emphasizing in its d800 review by pointing out the very unusual practices ("inordinate lengths") you need to employ in order to not smear a d800 image.

There is a sweet spot for mpix. More automatically equals better only in advertising aimed at amateurs.

It was clearly stated by Chuck Westfall that in order to get the highest fps, it was necessary to limit MPs. The target for the 1D series is always the best AF and frames per second. Traditionally, since the 1Ds split, these cameras have not had the highest MP count in the Canonlineup. At the announcement, any blather about MPs was marketing spin designed to blunt the customers' concerns about MPs since the line was being consolidated and the model with the the high MPs was basically being retired.
And this is why pro models costing twice as much as the d800 do not feature the d800's levels of mpix--because they make the camera less flexible and usable for making most images.

It is obvious that there are clueless non-professionals and clueless professionals in this forum. There are also knowledgeable folks, professionals and non, on both sides of this debate. Your comments show a disturbing level of ignorance for the intelligence of the audience you are attempting to address.

Bear in mind, the typical non-professional purchasing equipment at this level are professionals in other fields or successful enough to be able to purchase such equipment whose average income as a group far out-strip the average professional photographer's income as a group. These people are generally well educated and can read technical papers and learn proper technique and develop the necessary skills. IOW, you ain't pulling the wool over too many eyes.

Also, bear in mind that once the 1D X is released, you will be shooting with the amateur camera and some boorish pro will be hammering you. Remember, you are never at the top of the food chain in photography unless possibly you are shooting with the Hubble Telescope.

Funny you should say that. The last time I took the Hubble Telescope to a shoot, the model said it was too intimidating and walked out :).

Whew!!
You say you can see a difference at that small size? Yeah suuuuure...... you do!
I haven't printed to paper since 2005 so admittedly I may be a little out of touch with that medium but I do not think so. For my own consumption, I display my images on an NEC 2690 at 1800x1200 pixels. My viewing distance for sustained study of the images ranges from 12 to 18 inches. The additional detail afforded by 21 MP over 12 MP was clearly evident.

Are you saying that the 22 MP vs 36 MP comparison has perhaps fallen victim to the laws of diminishing returns as the OP seems to think? I am just curious as to your personal and visual evidence for forming that opinion.
There is one other reason the pro cams do not have more pixels. Only certain level of details is related to the overal meaning of the image, but much much smaller details are irrelevant. I define Image Domain as a full scope of details relevant to the meaning of the image. As such it is measured in mp and depends on the type of photography and display. It may vary from a very few mp in some photos, like mostly capturing bokeh, to 100 mp in forensics applications. But in general photography it is about 16 mp plus / minus 20% for portraits or landscapes. So 20 mp looks like a good sweet spot number from this standpoint as proven by success of 5D2 and other cams in this range.
This is a curious approach that does not deny the additional detail but claims it is insignificant or irrelevant. Can you give an example of what constitutes insignificant detail in terms of landscape photography because most of us pursuing this endeavor seem to have been pursuing the wrong goals then?

My only experince with photography gear is with the 35mm format and maybe it is just the format itself that renders fine details a bit mushy regardless of the final size of the images or print. But anything that can help a viewer resolve the wispy limbs and stalks of fine leafed bushes or grasses in the fore to midground of a typical landscape (without focus stacking) is helpful.
But if your specific type of photography requires more, this is fine. It just means that you have a good reason to show the level of subject details normally invisible by the naked eye.
Good one.

Since you mentioned P&S, OP title maybe sometime true among different formats of sensors if he didn't mention D800 and 5D3 ;) For example it's not true that a 16mp P&S will have more resolution than a 12.8mp 5D. Does this Nokia 808 has more resolution than D800? LOL.
Even a Nokia 808 pureview cameraphone has 41 MP
technology has moved on & left you behind.
I never mentioned P&S but I was responding to someone who did.
cameraphone is P&S to me.
The resolution is 41 MP fact.
Does it have better Image quality than the D800 , no
Does it out resolve the D800 , probably not
Does it out resolve the 5D , very likely.
Has it better Image quality than the 5D , maybe.
Really? Can you show some real world photos?
Does it take great pictures for a camera phone, yes
Are the 41 MP producing crap pictures , no
What's the standard of a GREAT photo? I have not seen any cameraphone takes GREAT photos on my standard of great photos.

More mpix does not automatically translate into more resolution under all levels of mpix, all lenses, all ISOs, and under all shooting conditions.
It does, all the time (assuming a "proportional" AA filter and everything else the same).

It is like arguing that if A> B then it is not always true that A+x > B+x.

Human stupiduty frightens me.
 
Speaking for myself, I am impressed about a meeting with Ansel Adams to get advice about lenses for your new view camera. Sounds like a very nice memory to have.

On the argument--all I am saying is something that is actually non-controversial--more mpix don't always lead to higher resolution because of an enormous variety of factors that can limit the resolution that is actually achieved. This is no more than DPR said in its review of the d800 when they emphasized repeatedly that one needed to go to "inordinate lengths" of technique to achieve the resolution that the d800 POTENTIALLY could produce. If you don't go to theose "inordinate lengths," you are unlikely to get the resolution, except on a hit-or-miss, lucky, low-percentage basis.

That is really all my post says.
would have been interesting to hear you argument against your concerns about pixel count. The Adams note was simply anecdote from the ancient past - it is nothing to be "impressed" about.
Ansel Adams was very conscious of shutter speed and subject matter. He generally found that a maximum of 1/200 sec was adequate for the majority of scenic work although, on rare occasion, used 1/500 when photographing in windy conditions or moving water and the subject was "close by" - at least that what he told me when I visited him in 1972 shortly after I acquired my Linhoff and he gave me some recommendations for lenses.

If that was all you were saying, then you’re right, it would not have
been controversial, it would have been stating the obvious. What you
also said was that:

"In such situations, the 5d3 will usually produce more actual
resolution in the final image and much more photographic flexibility
in getting the image you want in the first place."

And this is reason you are being dismissed - because it is physically
and mathematically impossible for the 5D3 to produce “more actual
resolution”.

All things being equal, 36 > 22 is true under all circumstances, even
if the difference are small. The worst case scenario is that the final
result will produce something that looks identical.

This is no more than DPR said in its review of the d800 when they emphasized repeatedly that one needed to go to "inordinate lengths" of technique to achieve the resolution that the d800 POTENTIALLY could produce.

Your problem is that you're reading your extrapolating what DPR stated
in their conclusion. The fact you are so desperate to dismiss is that
one does not have to "achieve the resolution that the d800 POTENTIALLY
could produce" to out resolve the 5D3. It will happen no matter what.
The other fact you repeatedly overlook is that the same "inordinate
lengths" are necessary to extract the best from the 5D3 – which is why
landscape photographers like Fred Miranda go to these "inordinate
lengths" to produce their images regardless of what camera they use.

What you're trying to convince others to accept is that unless the
D800 is shot on a tripod with MLU etc, then it won't out resolve the
5D3. No one is buying it because it’s false. That is why all 30+
responders to this thread are disagreeing with you – it’s not because
they are all Nikon trolls.

 If you don't go to theose "inordinate lengths," you are unlikely to
get the resolution, except on a hit-or-miss, lucky, low-percentage
basis.

Again, the same is true for the 5D3. It is a physical certainty that
unless you go to those "inordinate lengths" with a 5D3, it will not
produce the best possible image the 5D3 sensor can resolve, and even
then, it will still be less than what the D800 can produce under the
same conditions.

No matter how many ways you try to spin it, under the same shooting
conditions, with comparable lenses, comparable technique, the D800
will ALWAYS produce more resolution than the 5D3. That's simply a
fact.

The sooner you come to terms with it, the better off you’ll be, and
the more time you’ll have to take photographs.

Peter you don't own a 5DIII and you don't own a D800.

The D800 outresolves the 5DIII. You need good technique to see it, but it's there. If you know what you're doing the D800 can deliver more detail and deal with crops better. Yes, to get the best from either camera you need very good technique. It's true, you're not saying anything new, but you're desperate to devalue what Nikon has done. It also delivers more detail at higher ISO's and gives more room for PP. Nothing new there either. If you don't need that extra bit of detail and DR, don't buy it.

Why is this so tough for you to accept?

Same as my 5DIII. I used identical technique with BOTH cameras and saw the D800's potential on many shots and many more shots where we cropped.

Why is this so hard for you to accept?

Yep.
But the same camera used at a wedding or to shoot any kind of live event will not get you more mpix and may well cause you to lose shots because of things like increased motion blur
no, no, no.

You cannot "lose" any shots to motion blur with a high megapixel camera that wouldn't have also been lost if using a low megapixel camera.

More megapixels does not automatically translate into more resolution, but it doesn't translate into less resolution either! you'll always do at least as well as the low MP camera, and sometimes much better.
