HowaboutRAW: D810 sure wins for noise control when doing the ISO invariance thing.
As I've said, I'll look again.
If I find that DPR is using that SonyZeiss 55mm on the A7RII and the 1.8 85mm on the D810 there are other factors regarding noise not accounted for.
I've looked at the box from both at DPR, and that's not the result I'm getting/seeing when I shoot the cameras.
So indeed I've downloaded the DPR files.
ISO 50,000 is way beyond where anyone would use either camera.
That's D4S territory, and only just.
I will look at again at the DPR samples, but my experience with both tells me that the D810 is usable thru ISO 12,800, while the A7RII is being pushed hard above ISO 6400.
Perhaps 14 bit raws will help the future A7RII examples.
You can download the samples yourself.
Technically the A7RII has NOT been fully reviewed at DPR, though there should be studio samples, 12bit.
The DPR examples back me up.
Okay, you can make that claim, and it's been my experience.
It's not been my experience, and it doesn't conform to the results from this ISO invariance test.
I did download the plus 4ev and rev samples from both here at DPR, lets hope ACR 9.1.1 will extract these new full 14 bit raws from the Sony.
Just in the sample box the here, the A7RII is significantly behind the D810 all over the image, but of course that's a processed image of so sort.
That's a different point.
And the better way is to do zero downsampling but compare rectangles of the same pixel count, of the same shot area, of the same scene with the same lighting.
And from my samples the D810 is better for higher ISOs than the Sony by about 1 stop, and I've checked more than once.
What I've not done and probably won't is this ISO invariance test.
stevevelvia50: The nikon D7200 uses a Toshiba Sensor, an incredibly capable sensor, and when tweaked by Nikon even better. I believe in the D 7200 test it was quoted that the Nikon D7200 was perhaps the most iso invarient camera right now.
Okay, I guess that sort of works.
Nukunukoo: China will land some men there by 2021, close to the landing sites, so let's see what new conspiracy will come out. NASA paying off the Chinese to claim the remnants of the equipment are still there?
I'm quite sure it would be easier to orbit the moon with a photo satellite, with a modern camera, and image the lower part of the LEMs and the buggy.
Right, Samsung has to repeat, repeat again with the NX3.
The NX30's sensor is well respected, it's a myth that only Sony does good modern sensors.
agentul: men willing to risk their lives to do something great. this is why i doubt we will send astronauts to Mars: the western society is so risk-averse that they will demand 100% possibility of safe return. and no one will dare risk a mission failure.
so probably India or China will go there first.
or we figured out how to get there decades ago, and that's why the manned Mars mission was cancelled in the early 1970s.
The NX1 released in Dec 2014. You've confused announced with shipped.
Sony had already garnered a lot of attention for the A7 cameras, starting in late 2013. The A7RII is a current addition to that series. While the NX1 is a new series, same mount, for Samsung.
For H.265 video?
There are problems with still reasonably fast desktops and h.265 today in 2015.
Count reviews at B+H and Amazon.
The D7200 is better high ISO camera than the NX1, not by a lot, but about 2/3s of a stop.
Then NX1 looks to be popular in the US, but it's Samsung's first really serious APSC body, it's not cheap, a fact that indicates it is selling. It uses a difficult to work with video format.
The NX1 is still a specialized tool, I'd buy one, if I also had the money for new very very fast computer, and my current computer is far from slow, and the money for the better Samsung lenses.
junk1: Oly C3000 (cheaper version of the C3030) was my first digicam, around May of 2000. I think it had a $800 MSRP but I got it for around $600 or $700. 3MP, F2.8 constant zoom lens. built like a tank. I still have it, but the software for downloading images probably doesn't work on windows 7, and the memory card format is many versions obsolete, so not sure if I could even get a card reader for it.
I'm sure you can find an XD card reader on Ebay.
No, downsampling does NO such thing. 3% noise at X size is still 3% noise at X divided by 2.
As for these examples, and I'm not saying this is definitive, since I don't have base ISO samples of by own from both bodies, the Sony is noisier when pushed. (That fits with the Nikon being a somewhat better high ISO body than the Sony.)
Why would I do that, the equal size thing? Downsampling doesn't reduce noise as an overall fraction of an image.
You can move the box around all over the image, not just to the squares, and you can download the raws and extract them.
D810 sure wins for noise control when doing the ISO invariance thing.
