Do you think you will get quality images at iso6400 with any system, ever? they may be ok but useful for what exactly? Why is a forum dedicated to a lower-end of camera systems seemingly obsessed with iso6400? OK, maybe camera y isnt as good as x at iso6400, who gives a xxxx, buy some decent glass. You would have to be shooting in a tunnel at night not to be able to get a decent result with f1.4/1.8 glass at iso1600, even 3200 is the max you want to be at, shotts above these iso's are really because there is no alternative, we've run out of f stops, we are at long focal lengths, we cant use flash. But let's be honest most of us are shooting closer to base, aren't we?

Hi!

I like it when I can shoot at or near base ISO!

Nikon D3 ,Nikkor 200mm f/2G IF-ED AF-S VR
1/1000s f/4.0 at 200.0mm iso200

However, it's not always possible for me to do so. And even when shooting at high ISO's (Almost always in RAW) I sometimes intentionally underexpose if I need to avoid too slow of a shutter speed and use exposure compensation in post (the old "push processing)

Take the shot below.

I needed at least 1/500th sec to freeze the action. The nightime lighting was mixed and even shooting wide open (f/2.8) at ISO 6400 I was underexposing:

Nikon D3 ,Nikkor 200mm f/2G IF-ED AF-S VR ,TC 14 E-II
1/500s f/2.8 at 280.0mm iso6400

This young "Elvis" was gyrating enough that I was keeping motion blur even on some shots at 1/160th sec. The nightclub lighting was like shooting in a cave:

Nikon D3 ,Nikkor 85mm f/1.4D IF AF
1/200s f/1.4 at 85.0mm iso5000

Even with an f/1.4 lens, I had to bump the ISO.

And then sometimes I not only have to deal with cavelike lighting, but actual cave lighting!:

Nikon D3 ,Nikkor 28mm f/1.4D AF
1/60s f/1.4 at 28.0mm iso3200
