I never knew much about ISO, but a hundred thousand, I realize that it is an abnormal number, I'm afraid to cross the 800


eye that the ISO does not grow linearly but exponentially (basically doubling time)

100 200 400 800 1600 3200 6400 12800 25600 51200 102400 204800 etc ...

102400 with the yield is still a monstrous ISO sensitivity for tencologie current, but it is "only" 7 stop higher than ISO 800 although the number seems much older than you ^ _ ^


-------------

... Very impressive .. with my 5D3 using the 12800 only for emergencies, and I doubt I would go over ... so we have at least 2-3 stops more for the A7s (say 2 perche perhaps there is also the apiente PP to help) ... of course that is completely at odds with the A7r, for example, prefers the resolution ... for a professional or advanced amateur that does not make things too dynamic could be a beautiful pair of machines.


When is a camera sensor interchangeable?
Like, today I do landscape ... I mount the sensor with high resolution. Today I night, I mount the sensor sparse .... I do portraits, I mount fuji a xtrans to have beautiful skin tones .. etc ..:-D

Wow! Wow! you would not believe ... if you do not see it. But he knew how to develop sensors that Sony has been and still is, if you like, a small step above. But the form, aesthetics decentralized with that goal, but especially the "solidity" ergonomics of this camera ... to get his hair, because at the end of the dimensions, weight aside, is not that a real miracle of saving in the bag, or backpack that is. A form with ergonomic SLR-like eh no, Mom sony, it would be much easier, for example, for me us more than a little thought, abjuring Canon:-D, okay, it's okay, but this made a hundred thousand ISO leaves me tramortitowow! :-D. --- A question for Juza: The Vario Sonnar 24-70 f2.8 would be more powerful? This Vario Tessar find it, but not just me, a little '"fiacchetto" as a finalinition. The 16-35 f2.8 Vario Sonnar then, would be "explosive", not to mention, with adapter, 15 f 2.8 Distagon Juza ... if you can, try them, you'll love it:-D;-) - Sorry for the papyrus but I have a little 'with Sony, just a little';-) - Best wishes to all, G.Piero.

" I took a picture of my mimbo with the Canon 6D ISO 102 thousand, I 've only slightly cleaner camera raw,
If I can post the link ...
"

Entertainment! And it has almost double the pixel Sony A7s.
But what are we talking about?

Come on, smile a little:
I did the same photo recently at ISO 100 (but with the 17 TSE ...):-)
By the way, Emanuel, if you want to try give me a shout I'll do that again.

not bad, I assume that you have closed f11 to use this special sensitivity, as the scene does not seem to be so dark as to require 100K ISO, but being a test correctly analyze it as such, and I see a loss of detail impressive, perhaps due algorithms noisereduction I do not know ... I do not think this quality especially useful for f11 ... I would love to see them tested in a context where the 100K and iso are not justified where it enough maybe 10K ...

so, at first glance, it seems comparable to a shot at ISO 3200 with my D7000, ISO, ISO less, but from there to 102,400 !!! Incredible. Thanks for sharing, this serves more than words or explanations.

... Well, Lorenzo Pastors, thank you for the inspiration, Vs 100 102 400 ISO. Bearing also in mind the "fixed vs zoom", the comparison to the monitor, let me tell you, it's almost pitiful;-) ... even in tettaglio end on brick columns;-) and if so give me time, I dread to think what would out with the A7s set to 100, or 50 ISO wow! :-D but always:-) smile at above, a greeting, G.Piero

Looking at this photo I sense the potential of this machine but I can not of course to have a proper assessment of what to offer more or less than others. Rating which I've found in this comprehensive review www.luminous-landscape.com/reviews/cameras/sony_a7s_first_impressions. that clearly states the pros and cons of this product. Let's talk about two-stop advantage over a a7r (36mp) the sensitivity proposed here (ISO 100 thousand). Personally I rate very interesting in terms of research and development proposals sony extreme, very interesting A7S for video but in the end I think the a7 (24MP), the best solution to a less specialized. I am curious to see what we propose Juza return from Iceland, the A7S have the permission to take home and it would be prohibitively expensive with a FF with moreof pixels.

Salut

said he bought the Batman as well ...:-D:-D

in all seriousness impressive, perhaps opening the race to raise the bar of an ISO sustainable)

Lorenzo
We smile a little !!
Your shooting with cameras that have you got?
Surely your image freehand is not static unless you're like a tripod.
If I'm not mistaken Yuza writes "taken freehand."
I do not defend the A7S and do not denigrate any other body of any home fotografica.Di certain 12MP sometimes have flaws but behind every shot we are there.

Amazing .....
I would like just a camera with high ISO ... I was focused on 6d .... I .... I ..... but this € 2191 .... many ....

I agree with the experiments made by Michael Reichmann

- At ISO 3200 and 6400 the A7s is very clean,
- A 12,800 A7 is starting to show a little 'noise, but nothing to worry about.
- At ISO 25,600 the A7s can use a little 'NR, but not much.
- At ISO 51,200 the A7s is quite usable with some moderate noise reduction.
- ISO 102,400 is the extent to which I would like to use the A7.
- ISO 204800 is a bridge too far.
- ISO 409,600 is for bragging rights
I think you can have fun experimenting with new things

Now all sides are talking about two new Sony FF in January ...

Probably will mount in
(I do not think abiano done yet to fulfill the orders of the current ML FF 8-))

Perhaps one of these will have the fateful 54-megapixel sensor
(Not scandalized, the density is similar to the current APS-C 24)

the other, if they want, will THIS sensor and AF performance as that of a77ii.
the price could reach 2800 €

If we consider that recently improved support profesional,
probably the flagships Canikon could be in danger ....

@ Dominic Carbone
Well, of course I put the photo at 100 ISO, TSE 17L 5DIII and not to make a comparison (I wrote it clear that it was for " smile a little bit ") ...
I just found it funny that Juza has taken an image that more or less all visitors Morimondo taking; which I did myself n Sometimes, despite dresses 5km ...
About a steady hand, as you know, since I see that you sell a 24TSE [EDIT] , the shots with a tilt / shift lens must be carried out strictly on a tripod to level the machine; otherwise come out of the skewed images of what would have been obtained with a wide-angle normal.
Then that " behind the car there we are " These are the holy words.
