Nice catch.
Iâll just quote one amazon review:

I needed a basic camera for selfies and instagram photos, this was perfect! A little hard to use and heavy, but not too bad.â

Sure youâre not going to use these settings for portfolio shots, but there are reasons you want to crank your ISO settings from time to time, quality of the shots be damned⌠@Vnend below has covered a few of them. Iâm also going to throw in simple happy snaps. Just because youâre lugging around pro-gear doesnât mean you donât sometimes just want to capture some memories. These sorts of ISO settings mean that it doesnât really matter if youâre out camping and its dark, you can still do that.

ISO 409,600 would be useful in the dark of Cthulhuâs digestive tract?

One other techie note: even in the complete absence of electronics noise, at very low light levels youâll see a ânoisyâ image because youâre essentially counting photons. The photons arrive at the sensor according to Poission statistics (just like electron noise in very low-current applications), so youâll see a grainy image not unlike that produced with night-vision goggles.

Birders often have fancy gear and are going for shots that are just good enough to confirm species. I imagine there are similar situations with other wildlife. Also, surveillance, in the classic stakeout mode, which still happens a bit, I guess.

Unfortunately, shot noise comes from some very basic rules of statistics and quantum mechanics, so thereâs no way around it getting worse when you do this. When your S/N gets down too low, thereâs not much you can do with algorithmic noise reduction, either. The only way around this is to make the pixels bigger, which means either making a bigger sensor or reducing resolution, neither of which they appear to have done.

You know, 1600 used to be horrible. So much noise it made images useless. Now I periodically shoot at 1600 and can make something useable out of it. Pushing things out to 409,600 might make something like 12,800 useful. I donât see why everyoneâs getting on Nikonâs case for pushing the tech.

Yes. There is usually a high ISO NR option in in the camera, but it can often be better done in post-processing using the raw file. The NR algorithms soften the image by sort-of blending adjacent pixels according to some complex maths. The appearance of sharpness can then be recovered to some extent, but NR and sharpening algorithms essentially pull in opposite directions.
That was an impressive piece of complete bullshit.

Absolutely. Every generation of camera I have had has improved low-light, high-ISO noise. My latest (a D610) shoots very useable images at 2000 ISO. Very useful indeed for darkly lit scenes and hand-held long-lens shots.

Remember that many pros are shooting for publication. Normal publication means printed halftones â or these day, on screen â which is comparatively lousy resolution no matter how you slice it.
A bit of noise may make little or no difference to that audience, and a few extra stops â as noted, being able to stop motion despite using a long telephoto, or being able to use a long telephoto handheld or one that isnât ten times larger than the camera in order to gather enough light â may make the difference between getting the marketable shot and not getting it. (Shooting full-color available-light at nightâs another possible application that occurred to me.)
Fine Artists can and will turn their noses up at it, and thatâs fine; they arenât the target market.
, What I am wondering is what the response curve looks like in this mode and how much it emphasizes or de-emphasizes particular color ranges. And how much IR it responds to.

Yup, ISO is named after the organization. Same etymology as calling a CD-ROM image an ISO file.
It used to be called ASA back when it was an American standard.
It means Nikon has has officially become the Monster Cables of photographiles.

High ISO is useful. Sometimes you want to photograph high speed action under crummy lighting conditions using a slow lens. And if Nikonâs ISO 25600 setting is less noisy than itâs competitors (the higher ISO values are labeled Hi1, Hi2, Hi3 and Hi4, implying that Nikon finds fault with them), then a Nikon D4S could well be a valuable tool.
Nikonâs 800mm lens. Itâs $18,000, and itâs f5.6. It comes with a 1.2x teleconvertor, making it into a 1000mm f/8 ish lens.
What photos do you take with such a lens?
How about photos of birds in flight?
You canât just leave the shutter open-- youâll miss the action. And if itâs a cloudy day, you have no choice but to use a high ISO. A camera that preserves detail under such conditions would be very useful.
Of course, creepy PIs and paparazzi would also be interested in the camera. Bu advertisingt that might smear the brand more than an emphasis on sports and nature photography.
