, 1/125 f/8.0, ISO 204800, hand held.

Un altro test a 200K ISO - questa volta potete scaricare anche la versione a piena risoluzione! Ovviamente la qualità d'immagine perde moltissimo, però anche in questo caso considero la foto utilizzabile in certi ambiti (fotogiornalismo, documentario, paparazzi).

Another test to 200K ISO - this time you can also download the full resolution version! Obviously the quality of image loses a lot, but in this case I consider the photos used in certain areas (photojournalism, documentary, paparazzi).

What can I say .. as the first shot. Noisy but usable. It would be interesting to understand how much ambient light there was really

As I have written several times :-) there was very little light . We were at dinner in a dimly lit, already time to 1/125 at ISO two hundred thousand speaks volumes!

Seem irrelevant the arguments used in other 3d Emanuele. What a shame.

Even f8 now.

That this shot, where the reading environment seems irrelevant (assuming that the closure of the diaphragm should be justified by considering what cmq the pulping of the details), it could be done at f2.8 and 25,600 for the same shutter speed.

But do you really think that can be used for finding x documentaries and reportage (and it is said that it is not, indeed, the D4 certainly is) such a test at f8, is realistic?

Then, see if you do "ads" like even when you will experience the 1dx ...

bo, do not know what you mean by "little light" but last night with 85 F1.8 to F1.8 shutter for a 1/30 or less with 6400 iso 5d mk2. This for me is a little light! I was in the center of my city and there were cmq the lights on! I noticed that it would take a small source of light to transform a 6400 iso unusable salvageable!


In these situations it would be nice to see the test! That is, are at the limit of opening perspective superluminosa and where the only thing I can do is raise the ISO (something like portraits of course)

John, I apologize if I did not follow the thread and sign for the "arguments used in other 3d" .. but obviously I can not spend my life on photography forums, or not? I read when I can and if I'm missing something .. Well then, I think it is a drama

Other tests, similissimo the previous one, which seems to serve to flaunt "I have 204,800 ISO" but in fact .... there is little or nothing.
I would like to see a very difficult situation, with very little light, what pulls this D4. ;-)

They seem irrelevant arguments used in other 3d Emanuele. What a shame.


Why are nonsense.

So, let's see if you make "announcements" like even when you will experience the 1dx


The try these days and I really expect it to be in line with the D4. Obviously publish also for the 1DX of test photos, and as soon as they get the chance will do a side by side comparison between the two.

but last night with 85 F1.8 to F1.8 shutter for a 1/30 or less with 6400 iso 5d mk2.


1/30 f/1.8 @ 6400 = 1/1000 f/1.8 ISO @ 200K, or 1/125 f/5.0 always at 200 K ISO. In other words, the conditions under which you took you were verymilitary to those in which I've taken for these tests.

"seem irrelevant arguments used in other 3d Emanuele. Such a shame."

Why are nonsense.


Nonsense '
Indeed ... we turn to these words now.
Emanuele compliments.
compliments ...

Typical response when there are no arguments in counter-response. And indeed, perhaps it is tiring to read my (and those of others) to simply improve the way of test, or simply offer them perhaps with different titles ....

Honestly TE from this answer I would not have ever expected ....

@ Grievas
I did not have with you, cmq are short the other two 3d, you can give it a read if you want ... ;-)

It 'nonsense because I have explained many times that we were in low-light conditions and suitable for this test. If I had taken at noon you'd be right, but this was a very realistic situation for 200K: very low light, among other things with artificial lights. However you are free to believe whatever you want, I do not have to sell the D4 to anyone, you can also avoid such insinuations " see if you make" announcements "like even when you will experience the 1dx " because to me the brand really matters zero, I'm not for or against either of them.

No reportage close down to f8 to go from 25k to 200k iso in reality.
Why this shot the repotagista brought him home, in that situation, at f2.8 and iso 25k.

The substance is that to take the test you had to close the aperture to not overexpose too. Ergo the light conditions were not such as to justify those iso or closed so that diaphragm. (Even though the light was definitely a little).
In other words, even what I contend is such a test draw the conclusions that you have drawn. Why this is not the reality.
And I think whatunque photographer here can not deny what I say. So I do not come and say that I say nonsense, because these are not.

And as you have often done much more reasonable test in the past, I expect you to continue on that line. I see no reason why it should not be that way. That's why expose a criticism towards you (constructive of course).

Then, try again to explain for the umpteenth time: I'm testing ISO 204800. If I do a test of not shooting ISO 200K 25K iso.

It seems absurd to say that each ISO sensitivity must be tested in the condition of light that gives the time limit at f/2.8 and 70mm. Take a paparazzo in your shooting with a 70mm? I imagine instead that you use at least a 300 or 400mm ... in this case the time limit is much higher, at least 1/400 or faster, then exactly as in my tests.

The light, I repeat for the umpteenth time, was very poor. Next time however I will try to shoot while mounted lens cap, maybe it is dark enough for you :-)

The last advice I can give is to try and assess the D4 for your taste what are its limits.

No need to repeat it, Ema, of course. And I agree. (Like I said in the other 3d). But you have to take the test with just a 400, in fact. Reasonably f2.8 or f4 ... and reasonably outdoors with a greater distance between the lens and subject. These (especially the distance between subject and camera) are substantial difference. As well as taking in external funds also would be fairly light "difficult" (even with the same lighting, this would probably be less uniform).
The fact is that with your test can not determine what you just told me. This is the limit that I discuss.

Cmq I do not advocate that the test must necessarily be made to limit shutter speed (aperture / time). But express doubts about how, in reality, a reportage / documentarista, before using 200k iso that, to date, of course, still have many limitations, would work on other parameters, starting from the diaphragm.
In short pass to 200k with less light than what you had.

I tried the d800 for the moment that no doubt seen the mpx in question has excellent behavior at high iso.

Sorry, but because the performance of 200K ISO should depend on the ambient light? Should not depend rather on the light that reaches the sensor? So if this photo was made with less external light, but keeping the same histogram should be identical, right?

.. would go to 200k with less light than you had


I could not agree on this. Honestly, I think my 50d with 50ino would do a photo identical to this one, looking a bit 'iso and lowering the shutter speed. A night shot might be more attractive

@ Grievas if I did the math there are 2 EV light just over a candle ..... for the rest to Rome if he says no head in C. ... ahahahaha is a test is a test stop! even if that situation is not adequate because the you could shoot with shutter speed and aperture and iso different I do not see what the problem is ..... important if the then head another machine that you do it on an equal footing stop! much better this type of testing that all those facts precisini with a prepared set ...

it is evident that remains on the surface Blade ... Read my last msg of 10:55 perhaps understand better. None required no prepared set of course ... Besides, look at the purpose of this test ..

But that speech is that? .... considering the static nature of the subject with the D4 abbassavi abbassavi the time you opened the aperture and iso party's over .... BUT THIS IS A TEST!! because then I can say that if the subject was stopped, took the stand and was taking directly to 100 via iso, but .....
