How do you bring down noise without losing much of sharpness even at ISO of 1600?

    Good that you caught this: "Many,many times, people resort to ISO 1,600 and then under-expose, at say an effective Exposure Index level of say 3,200 or 6,400 or worse, and it looks like rubbish! But if you have the ISO set high, AND you expose adequately and there is actually LIGHT present, 1,600 on a 5D Mark III is very useable." I'm going to re-emphasize what Derrel said here. This is the key! If you're going to raise the ISO then raise it as far as needed. The worst thing you can do is be afraid to raise the ISO and so hold back and as a result underexpose at the lower ISO -- huge, huge, HUGE mistake.

    Here's ISO 12,800 with an APS class sensor (Fuji X-T2). By the time the image is down-sampled (2048 pixels in this case) and filtered (lightly using Neat Image) it's completely serviceable. To illustrate the filtering issue I inset a box over the image with the unfiltered version inside the box. Noise filtering for the overall image is light because detail is more important.

    I would love to be able to shoot at ISO1600 for my football games at night. That being said, I use a crop sensor 7D mk II and will shoot with ISO up to 6400. Most of the time, I just use LR to process these images and only use the sharpening and noise reduction in the details panel. My go to settings for that are Sharpening 60-70 and NR of 30-40. Here is an image taken at ISO2500 at f/3.2 1/1250, where I used 70 and 30 for sharpening and nr. I was probably 15 yards away with a 70-200mm f/2.8 at 105mm.
