>>2953559Yeah. The recommended max of 6400 is so useful at the resolutions I generally need that I don't even care when it maxxes out unecessarily. I'm infinitely more likely to be annoyed by camera shake than noise.
That said, i've tried using 51200 on a couple of occasions, partly just to see how well it works, and partly becasue it was really fucking dark and I had a long lens I usually reserve for the daytime.
It's very useable if you need it, and at one point I was setting the automatic max to 16000 and still getting good results as per 6400, the only thing that really puts me off using higher then 6400 all the time is the weird and sudden whitebalance shifts that you get....and I try to avoid processing if possible, especially on everything-is-crap-anyway-shooting like at parties. So trying to adjust WB in completely unnatural light is a bit more tedious than I like. But yeah, it's very useful to be able to shoot in the dark like that if you need to.
