Does anyone even bother shooting at 51,200? I think if you want to go that high, you're going to go for a 1DX/D4. Even on a K-5, one would keep it under 10,000 for anything resembling a keeper and carefully thereafter.

That could have been taken with a smartphone.
Got a bigger version with EXIF please?

ISO51,200 is all but native: the signal is heavily amplified.

That's 51,200.

What would a smartphone pic look like anywhere past ISO 800?

At 12800 iso my Sony NEX-3N that cost $180 for new body on ebay looks almost as good as the $6,000 D4 IMHO.

We weren't discussing that.

No, nobody shoots at 51,200. On our entire site there are less than 10 photos shot at this ISO (that aren't test shots).

The only use i have for the Iso 51200 setting is to check composition when framing dark night land/starscape shots.

The most I do, and I'm shooting really dark scenes with lots of motion (metal concerts) is 6400, then I push exposure .39 stops in post processing (apparently equal to an additional 2,496), so let's round it to about ISO 9000.

I can never imagine doing anything past 12,800 and 25,600, I guess, is the max I'd ever even use. If I was going much higher, then I have to go with a faster than F2 lens (or F2.8 in many cases) and/or go full frame.

A smartphone, in my case, the largeish-sensored Nokia N8 is not even coming close, so I don't understand even this comment, unless it means "at 51,200, the K-3's output looks like a smartphone at ISO400".

I top out at ISO 1600 and add brightness in LR4. from 2 to 5 stops, no problem. As good as ISO3200 or better than using ISO6400 or 128000 in camera

I recently shot a wedding with my K-01 and most of the time I would be on ISO 10,000 and they were all perfectly usable. And do notice I said usable, not "as if I shot them on ISO 100".

You must have a far better post-process than I do. Depending on light condition at the time of the shot, I get frustrated with ISO 400+.

I guess you never shoot night rodeos:


White helmet 2 - Kyogle Show Rodeo 2013

ISO 10000 on the K-5. Last rodeo in June I was even shooting ISO 25600. Sometimes it's either shoot high-ISO, and accept the image flaws, or put away your camera.

It would be excellent if the K-3 worked better at those ISO extremes than the K-5. Fingers crossed.

I shoot up to ISO12800 with no fear on K-5IIs, and I used even ISO25600 for a web...
I there is a chance for more usable ISO51200 I would definitely find the occasion to use it. And usable ISO51200 means much more usable ISO25600 and pretty good ISO12800 (not only for a web size pictures).
