"Confirmed Specs Comparison of Nikon D5 vs D850" ... ?

Gjesdal

Came across this video today, and if it is mostly true about the D850 I will have a hard time heeding my words to my wife "I don't think I will replace the D810 with the next model"...


"Confirmed Specs Comparison of Nikon D5 vs D850 . Both DSLR Models are going to Launched in 2016."

I follow this channel on Youtube for the information about video for DSLRs, but have no idea how trustworthy it is when it comes to rumours...

Sports

Sorry, but this looks like total BS.
Even some of their D5 info looks like BS, so how would they know about a D850?
They have absolutely no idea. At. All.

Gjesdal

What I thought too... :-(
Can't recall read much on 810 replacement, so had to check it out.

Paperman

Why does one make a video when all he shares is text ? :-?

Ironheart

A few things don't pass the sniff test:

Tilt screen? We know for sure the D5 won't have this
4 card support 2xXQD and one CF and one SD? Not likely
Expeed 5 (possible dual Expeed 5) this is pure BS, as the Expeed has been dual processor since at least Expeed 3
Got the number of focus points wrong
Got the ISO number wrong, and weird extra comma 1,02,400?
Built in Wifi and GPS

Anyway, happy to be proven wrong on any of this, but seems weird to me.

D850 is 100% fake according to NR admin

Msmoto

Daydreams.....how we love to engage.... While the specs look very nice, what is impressive is the music and data flow....done like a mystery novel, about 100% fiction....but based upon some threads of truth.

Photocell

The only truth to this is that eventually there will be a model that replaces the d810.
Now when that will happen is anyone's guess, I'm guessing 4th quater 2016 an updated model will
Be announced. The one thing that will be correct is that 4K video capability will be available but so
It will be across Nikon product line in the future, the same way we migrated from standard definition to HD.

Photocell

I am wondering if during CES or slightly afterwards if besides the D5 another camera model would be announced now. What are your thoughts?

Sports

It's not unlikely, but it won't be a D810 replacement.
Other models will be replaced before the D810, me thinks.

Gjesdal

Will Nikon really let Canon sit there with the highest resolution DLSR camera? I don't think so. If they can bring out a camera that will beat Canon I think they'll get one out as soon as the D5 have been available for a little while

WestEndFoto

Yeah, the D820 will be out in 2016. That is Nikon's refresh cycle for their top cameras for the last 15 years. They will stick to it for this generation.


I do see it slowing down in the future however.

What happened to Moore's Law? There was a time when you said it would go forever. I'm just yanking your chain.
I do think the rate of megapixel advances will slow a bit, but 120MP is essentially here if you scaled-up a Nikon1 sensor.

I doubt any lenses would match the resolution of a 120 megapixel sensor on FX. Therefore, there would be no point in introducing such a sensor. Perhaps the finest lens at its best aperture would exceed 80?

I also doubt that a CX lens equals the sensor that you suggest above.

And I would love to be convinced that lens are better than I am thinking.

if the 1 sensor really scales to 120mp density on fx, then perhaps some people with the 1 system + a lens adaptor and some of Nikon's pro lens lineups can chime in..

I have all of the above, and it works just fine. I won't be able to post any pics until next week. What @WestEndFoto is forgetting is that CX only uses a very small circle (hence the 2.7 crop factor) and it is very much easier to design small, accurate, low-aberration lenses than large (FX) ones. Also, if you use an FX lens on a CX body, you are using the sweetest, sharpest part, the center.

Here's the math:
CX = 13.2 mm x 8.8 mm
FX = 36 mm x 24 mm
J5 = 5,568 x 3,712 = 20,668,416
CX sensor scaled up
(36 / 13.2) * 5,568 = 15,098
(24 / 8.8) * 3,712 = 10,123
15,098 * 10,123 = 152,837,054 or 153mp

When I said 120mp I was thinking of the previous version 18mp sensor, not the 20mp on the J5. Regardless there are much higher pixel densities being made in limited quantity today, than the 36mp D810 or 50mp 5Ds. Both Nikon and Canon have shown us prototype 250mp+ full frame cameras. 200mp+ sensors are available for scientific and military use. They just aren't practical for consumers, yet.

What is so interesting to one who remembers the days of shooting at ISO 80, Plus-X, developed in D-76 for 80% of normal times, all of this high pixel density, super high definition talk is mind boggling. I am still amazed by what I get from my D800E...but I suppose things can be better.

As to resolution, i am still planning on working out a system to shoot my Schneider 90mm f/8, Super Angulon on my D800E...to check if the resolution is as good as I think it might be. And this from a lens which is 50 years old.....

Actually I thought you were going to say that when I wrote my post. It is not that I am forgetting, it is that I am not sure I agree with you, both from a laws of physics and a practical engineering standpoint. But if you convince me I predict it will be from a practical engineering standpoint.

The CX system does demand lenses with greater resolution; just look at the MTF charts, which are displayed in greater line pair numbers than the F-mount lenses. Regardless, the CX images are still not great at 100% mag, but at least they do not suffer the smearing effects of P&S cameras.

@Ironheart using the below measurements gives roughly the same results: ~154MP for the 20.8MP J5 sensor scaled up to FF.

On CX (v1) my old 18-200 DX is really quite amazing.. this lense is a "hidden gem" on CX. I investigated this and on the DXO charts I found that the CX Image circle of this lens is really sharp.. which Is what i found..

From 18-35mm.. Its really an awesomely sharp standard zoom and it even goes to 200mm and its still sharp .. did is say its sharp? its sharp :-) .. i got my 70-200 F4 and planned to use it on CX with tele-converters .. :-) and ... If some one else is contemplating that I would say don't bother.. yes sharp but not worth the difference and effort, get an old 18-200 :-). I am curious to try the two 18-300 but I don't have them ...

snakebunk

If the 18-200 DX is sharp on CX I imagine that for example the 200/2 is even sharper, which means that there is use for a lot more pixels on fx cameras (which is according to my experience with the D800 and Sigma 50/1.4 Art). Maybe not in the corners but in the center.

This seems to be a popular discussion by the way .

It is easier (and cheaper) to correct a lens for a smaller image circle since corrections to the edge may compromise corrections for the center. Every parameter needing optimization compromises the others.

Lenses for small sensors can have remarkable resolution, the Olympus 4/3 lenses are a good example.

One of the reasons that modern lenses are so sharp is that designers can correct for factors like distortion and to a lesser degree vignetting digitally, and are then free to optimize others.

Cost of course is the 'other' factor.

Industrial (used for semiconductor traces), and military (used to read Pravda in Gorky Park from space) optics are routinely corrected to resolutions and contrast far beyond commercial designs, but can cost hundreds of thousands of dollars. Reading H'aaretz needs correction from right to left, which is still in design.

An example of what can be done when the cost compromise is removed is the new Leica APO summicron which is remarkable across the frame, but costs $8,000 for a 50mm F2 and is back ordered 3 years.

There are also numerous benefits in rendering, to having a sensor that significantly out resolves the lens. The downside being that each new generation camera has eaten my prior computer. With a D810 as my primary camera, I am now using a current generation mac pro (6 3.5 ghz physical cores, 30gb backplane) and do not know where to go from here.

"An example of what can be done when the cost compromise is removed is the new Leica APO summicron which is remarkable across the frame, but costs $8,000 for a 50mm F2 and is back ordered 3 years."

Ordering that may be a bit of a gamble because 3 years is a long time - maybe other lenses may be closer to it for a lot less money?

I agree, I have not ordered one. For a Leica 'M' mount there may not be many choices, but my series IV 50/2 (non APO) summicron keeps me happy.

My point being that there is a lot of headroom in the science of optical design to keep up with sensors if it is needed and can be paid for.

Fuji's 90mm F2 is a good example. Their entire lens lineup is probably design crumbs from Fuji's industrial and military optics business.
