Canon 5D Mark IV High ISO

One of my photography readers had a question about the High ISO capabilities of the Canon 5D Mark IV.  So what a great opportunity to test it!  At dusk, I put my camera on Aperture Priority mode and dialed the aperture to f/3.2.  The shutter speed was really low, but I wanted to see how the camera would handle it.  Absolutely no processing, just converted them from RAW to JPG with a limit of 8M.  Some of my high ISO images:

ISO 32,000 @ 1/30th of a second.

Yeah, OK, not that I'd ever go to ISO 32,000, but it's nice to know I could get a "decent" image there if I had to.

ISO 16,000 @ 1/15th (hand held with the 70-200, BTW)

Better.  I could definitely use this image if I had to with a little processing.  Probably would be a decent Black and White where the grain would enhance it.

ISO 10,000 @ 1/10sec.

A little motion blur here, but I am more looking at the grain of the image.  I could definitely use this image.
