Significant but it could not be otherwise ...

I honestly do not see fine detail remarkable, and remarkable mean deserving of 3500 euros and a machine focused precisely on the sensor / IQ

I shot at f / 8, which is the smaller aperture that can be used on sensors with pixels so small to have perfect clarity; already af / 11 diffraction is felt

but the diffraction is not tied directly to the lens? f is a fraction of the diameter, the diffraction is a phenomenon related to the diameter of the lens ... so that the lens did you use? :-)

diffraction noise ...? (Already at 100 iso I not think) goodbye to the advantages of the FF

I can already hear those words: 50 megapixels and produces noise ..... If it were up to me who the courage to say certain witchcraft, daughters they would do to their sensors, images seem to me with a very good definition, then c ' It is always the contrarian ......

It would be interesting (for me) to see a shot in the wild, a basterbbe giradino, with elements such as trees and foliage some artifact-type house, with pictures taken at the same time and if possible with the same perspective, comparing full images and clippings to 100% no sharpening of raw or with the same capture sharpening, opened with the same software, between D800 and Sony a7 this.

unfortunately we were all lined up, Mr.. Nicofoto. It is not a question of diminishing the work of technicians Canon, if I purchase a full frame from 3000-odd € I want to see a clean file to ISO 100. It will be legitimate and respectable opinion or not? Some like the high resolution, others like cleaning, the world is beautiful because it is different!

I would say that's not really the best photo to evaluate the yield of 5DS, as well as that of any other machine ...

Well I honestly all this quality dislocated jaw do not see it to be honest ....
Considering that it is a photo taken with one of the lenses more sharp in absolute I see in a lot of noise to be an ISO 100 (it can be seen well in the crystal blurred in the foreground). Then for the love of god quality it is more than good but not to cry masterpiece refelx by;)
(We do not start the usual battles nikon canon, my opinion is a pure objective).
However, we expect more photos from good to better assess Juza :)

a file 50 mpx with this quality? very well, I think that canon is starting to get serious, and this can only please me to "nikon user", because otherwise without the eternal pursuit canon vs nikon vs canon would not progress ;-)

Kappa excuse, but that you can evaluate the quality of a picture like that? among other things due to the form of the picture, the PDC is very small ...

It seems to me equal to or 5D. .. :-( (Needless to 5D Mark II or iii).

Having said that I understand little of comparisons ...

But this shot does not seem entirely appropriate to make evaluations and test !!!

Anyway thanks are really curious ...

Mah ?! Maybe because it's almost a beginner, but it seems obvious that a 50 MP sensor you can not evaluate by a single click. Juza wanted to make an advance, which I really appreciate. We'll see the whole review. We are a great zoo, animals of all kinds, from ants to elephants, and there will never be something that goes well at all, not even the half, even a third. Imagine then if it is a question of photography, in which we break the hair 125 and beyond. Take it easy !!! However, when I took the first digital 8 Mp, I do not know the size of the sensor, several years ago it seemed to me already something great. I now have a 20 MP FF, a good jump. I'm just curious as to how they are 50 Mp, in the hands of Juza then!

I shot at f / 8, which is the smaller aperture that can be used on sensors with pixels so small to have perfect clarity; already af / 11 diffraction is felt (although it is still acceptable), while f / 16 on the diffraction compromises the detail. Of course, nothing prevents you shoot at f / 16 or f / 22, which not only takes advantage of the real resolution of the sensor.


Excuse my ignorance ... Juza me explain this sentence?
As I understand it with a sensor from 50px to f8 I have the utmost clarity.
But if I want to have a maximum pdc ... I am not forced to close, and then I lose detail?!?

exact, if shots at f / 22 you lose detail and resolution, in practice it is as if scattassi with a 20-megapixel camera instead of 50 (although gains depth of field).

Regarding the diffraction it is often said that once the Airy disk has exceeded the size of the photosites begins to occur and diffraction loss of resolution, almost in direct proportion. In reality it is not so because even though the first minimum of interference is at a distance overflowing the photosite, assuming the maximum at the center, most of the energy still falls within the photosite while only a small fraction of the intensity It is complemented by the adjacent ones.

Ok, but there is a relationship / formula to be done to figure out the correct opening?
Example: if I take a 5dmkIII from 23mpx, quele may be a diaphragm max?
But if I look at a lot of photos of the forum of landscape always known diaphragms f11 up
