Re: Take it back

You have highlight tone priority set which increases noise (pg 146 in the manual). You also have peripheral illumination correction set which can also increase noise (pg 156). Note that with HTP disabled you can also get some noise from auto lighting optimizer. For lowest noise you need to turn that off too.

As you've noted, DPP does a much better job with the noise, at least on the first file. The banding seems totally due to the LR conversion. The second file is two stops underexposed which isn't going to help with shadow noise.

A last thing I noticed that may be relevant to your first shot is the 5d3 rendering shadow detail similar to noise. I've seen this in shots where shadows without detail were noise free but shadows with detail present looked noisy.
