645Z Noise Reduction Workflow

Hi, I recently shot images of my tennis team in an indoor facility. I used f/4 at 1/500 and iso 3200 in raw. The files have visible noise. Is it better to apply noise reduction in lightroom or leave them untouched and use something like Topaz Labs DeNoise or a combination of both? Thanks in advance.

I usually set 5 luminance and 20 color NR for ISOs under 3200, and bump it up to 15/30 for higher amounts. 12,800 needs around 25 luminance and 35 color.

Compared to my previous cameras, I honestly see no point in thinking too much about NR, chroma is extremely easy to remove with low values, and luma noise is rarely intrusive. Given that you're looking at 51MP, it makes for a false impression of how much noise you'll end up seeing in print or web, assuming you don't intend to make very large prints from the resulting images.
Here's an image shot at 12,800 and then pushed a bit, no post-NR applied except for some modest values in Lightroom:

ISO3200 should easily be usable for up to A3 prints that look nice and smooth even without special NR treatment. I haven't had to fire up Dfine 2 in a while now.
