Test photos, Nikon D4 to ISO 204800 sent on August 25, 2012 (12:16) by JuzaPhoto Samples. 112 comments, 23069 views.

, 1/400 f/4.0, ISO 204800, hand held.

Non soffermatevi sul fatto che la foto è orrenda: è solo un TEST :-) La cosa interessante di questa immagine è che è scattata a una sensibilità pazzesca, 204800 ISO... duecentomila ISO!!! Le condizioni di luce erano tutt'altro che ottimali e ho voluto provare la D4 a una sensibilità talmente estrema che normalmente non verrebbe neppure presa in considerazione. Questo è il risultato: certamente c'è un'enorme perdita di qualità d'immagine, ma tutto sommato direi che è utilizzabile per uso giornalistico o per altri campi in cui la scena ritratta è più importante della pura qualità d'immagine. Ovviamente la foto è stata elaborata con una marcata riduzione rumore.

PS I've never talked to test insignificant Max .. I question how "advertising spot" with which it is presented and then, yes, I say it is "unreliable" ..

Or even you'll be using 204K ISO 1/8000 f5.6 to stop a hummingbird in flight in a situation much brighter than this (I do every day:-D). So what? no shots because there is still too much light and not enough put in crisis the sensor? And so you get a clibrì all moved?

PS: I am still talking to absurd.

You realize that everyone has their own situations in which it is most often shoot at high ISO, who you are like me at night, some during the day, who at dusk ... Neither my situation, and thy would still be exhaustive to describe the behavior of D4.

But it's not an advertisement! Juza showed ONE of situations, and is reliable as all the others.

considering Questra try a sort of "average" situations: some shooting at high ISO in good light situations ottenedo of the best results of this and other like me shooting in the dark at high ISO the results are far worse

We speak in concrete: the ISO 12800 that I use often at night in the dark pesto I make a photo rather noisy. The same if I use them in an oasis of days to stop a heron in flight, I return a photo with very little noise. This situation is in the middle: not dark, not light good ...

In my more than time / diaphragms are talking about a still picture drawn, which shows the potential but not the effective yield. For the use of ISO 204k there may also be, I agree with the fact that a trip to the theater where you need to get that feeling stop a moving subject would be more suitable, but nobody buys a ticket to a test machine, one takes a situation "type" pulls the ISO and was astonished, perhaps under different conditions would be even more impressed and others are disappointed.
However I do not think that the 204K should be seen only in reports, should be assessed also a sport with a quick scene (eg tennis racquet courts) where less than 1/2000 get shake and see at that time and how much engraving keeps the sensor sensitivity . And if tennis shots at night without too much lighting least sixfar from those needs. Another thing misleading is the fact that the photo 51200ISO longer appears engraved the point of focus, but you can see banding and little detail in the hair, which looks better in this at 204K.

Allow me to post a test I've just done, certainly not in the best way possible, but that compares the performance of the Canon 7D at 6400 ISO, two shots in AV stand, life view and auto exposure.
The first shot I made in my room with the windows open (a fool, I know, but at least I have not compared different photos ...), the second with the windows closed.
From the time of click you can see that the light is reduced to one fifteenth, but the performance has not changed at all.
Ovviemtne comparisons should be made of areas with the same brightness (same ISO equivalent) and not in areas where the opening / closing of windows has upset the brightness.
I'd like to hear your opinions.

No correction of the noise (or brightness color, no detail, curve, etc. ... I just balanced the white label on the hard disk).

So I am or who I mean bad, or you who do not want to understand


neither Max .. would be enough to recognize that the conditions in which it was done shooting test facilitated the response of the sensor to the ISO sensitivity.

then tell me if that would have to choose iso 200k to freeze the flight of a hummingbird with a faster shutter speed and would have those results, ok, you're right ... and I'm good results in sensitivity crazy ... but it is not the snap we're talking about!, in the first step of the test - in the particular lighting conditions, subject etc - the choice of utlizzare iso 200k facilitated the response of the sensor, or if you prefer, do not put the whip

Ok, but on this I have always agreed with you. I put the whip even 6400 ISO with my night shots and I made the difficult, but there are many sports photographers, wild, theater, concerts click at high ISO in low light usually much higher than those who reported Juza .

If the result does not change means that offferenza of EV is not sufficient. Stay in one place, the machine on the tripod. Shoot at 6400 iso at sunset (you hundredths of a second if not more) and then wait until the night (moonless preferably) where you have to expose at least 15 sec. Then compare them. If you want to change! Change the 5D II, III, D800 and D4 ... Wilt that the 7D does not change?

Ah well ... thanks from 1/90 to 1/6 the decrease of light is not sufficient to appreciate different yields.

Try it when you get to 1/1000 ISO TA 6400 and TA 15 Sec ISO 6400, as it happens to me in real life, then tell me if there is no difference! A drop of light as it gives me different results!

there are many sports photographers, wild, theater, concerts click at high ISO in low light usually much higher that these Juza reported.


and this is me to agree with you

will be true
but then when you look at the picture you see flat images without many tones which probably served
then can be useful to the lack of tones sometimes become creative
but in 90% of the images you appreciate other things
would be useful to assess how the ISO image holds
are excluded special cases, exceptions etc. ....

Max
obvious that everyone has different needs in the way of shooting.
but there are certain common points of reference, on which all agree.
And one of these is the high iso, that one does not go to look for them if you do not really need.

As for high ISO and fast shutter speeds, absolutely real cases, this no one has ever questioned anything.
But surely it is not that if the car makes it so quite acceptable in a static portrait to 200k iso with fast then surely it follows that in a portrait at the theater with a moving subject then you definitely will make good. Change the distance to the subject and also changes the difficulty of the shot ...

Anyway how to write cmq is clear that you agree too, only if the subject is therefore notYou can disagree too:-D

skip the rest because it is a speech hackneyed but I would like to point out what is said every now and then taking a wild gem ....

Not even the EOS 1V is small and portable. And 'bigger and pesande the D4 soon.



EOS 1V -> 161 x 120.8 x 70.8 mm 945 g

nikon d4 -> 160 x 157 x 91 mm 1340 g

in practice d4 is only 2 cm thicker almost 4cm higher, weighing only 42% more than the canon ... the face that the old 1v both moments big and heavy ...

I do not see how it could be heavier than the analog since it contained the missing quite a few little things. same thing with the Eos 1n boxter and 24-70. weighs like a 5d with the same lens (most gram gram less)

Goodness is a figure of speech! Where I come from we say so is to say that there are there like weight! But all you have to do? As we want to make precisini, there was talk of digital and analog not only referring to the top of the range, so we are wanting high quality digital SLR definitely read more of Eos 1v. As there are analog and digit pocketwings pocket. So as good ....

Or to let me know I have to mention models, size, weight and type of material they are made of?

It 'sure that the digital weights a little' more, but not to create problems appreciable (except some extreme cases)
