I've attached an image I shot today, perhaps it's not the best sample image because of the low light and high ISO, but it seems like the lower-lit areas are just not as clear as they should be. I can provide other samples as well if it's helpful.

Think of it this way -- light is information. At 1/4000 sec exposure time you're getting very little data in the shadows -- there's practically nothing there to work with. At 37mm focal length you should be able to handhold that at 1/125th easily and you'd have 32 times more data in the shadows to work with.

Brilliant response! You can see the noise reduction artifacts clearly in the grass just to the right of the top of the waterfall - what Henry ("blue skies") would call a failure of the "fur test."

Yeah, it's the noise reduction that is harming the low-level detail the most, I'd bet.  I turned my NR to "Low", although that isn't even the right answer -- the RAW processors on the computer will do a better job, and I can fine-tune the results.

When it comes to the waterfall, instead of trying to freeze the action, most people would want some motion.  I would have tried for as slow of a shutter as I could.  But without an ND filter, 1/125 at ISO 100 and f5.6 might have been worth trying.  Maybe something like f8 and 1/60?  A little blur to the waterfall, plenty of DOF with f8, and a slow enough shutter to hand-hold.  I bet the results would look a lot better.

But even if you wanted the water motion frozen, I would go for, say, 1/1000 or something to get something more reasonable for the ISO.  1/4000 just seems needlessly fast.
