Here are 2 shots of my daughter's volleyball game at 8000 ISO. How does the noise look. Is this what you would expect for this camera?

Thanks

Tim

I think the no-NR files show a lot of potential, especially for ISO 8000. The 45 Lumi NR helps a lot. Did you pull back the exposure, or were they shot at this level? You'll get better results from your processing by adding +1/3 - +2/3 EC to shots like these. Pulling the exposure back down kills a lot of noise all by itself. At high ISO on the 60D, I'd sharpen about 35 and mask from 40 to 75 depending on the shot. Post up some more of these.

I made sure I didn't have to push the exposure, but I didn't add +1/3 or +2/3, so there was nothing to pull back. I was not aware that pulling back exposure killed some noise. I just thought you wanted to be sure and not under-expose any. These were both sharpened at exactly 35, with a mask of 50.

+2/3 if you are shooting raw is usually no problem at all. Check the 'blinkies' to make sure you are not blowing important highlights. One other thing that can help with the histogram/blinkies is to set up Neutral (0,0,0,0) Picture Style, then shoot raw. Picture styles can mis-represent the histogram when you are shooting raw. That is because histogram is for the temporary rear display, and gets whatever Picture Style you have set. N(0,0,0,0) is as close as you can get to raw.

I was extremely disappointed. After 6,400 it gets murky.

If i had never shot with a 6D or Sony bodies then I probably wouldn't mind it, but it's kinda embarassing. Even the bottom of the barrell 3 year old crop NEX bodies have better ISO.

The autofocus totally makes up for it though. Still can't get over how good it is.

By the way the EXIF for your shots say 6,400? In camera 6,400 is awesome. After that it goes downhill.

Those look well exposed and the noise looks normal for that high. Nicely done.

Noise looks normal at 6400? If you can see it at that level, there is too much of it. A properly exposed and processed ISO 6400 shot should be pretty darn clean. At reduced size for web presentation you shouldn't see any noise at all.

Not sure why EXIF is showing 6400. These are definitely 8000. (I went back to lightroom, and also looked on Flickr.) If you click on the FLickr link, you can see that it is showing 8000.

You still want to push your exposure up to the right to get the best results. Also shoot a custom white balance or correct afterwards, strange color casts will enhance the appearance of noise.

Here is one of my iso 12800 tests and what I am able to pull out of them, in subsequent replies later in the thread.
https://photography-on-the.net …showthread.php?​p=17685596

If you are careful and good at post processing, you should be able to shoot 12800, and get a stop of noise out of the image, I feel.

I think your examples are the true test of low light. You are shooting at 1/640 in a poorly lit gym.

Indoor volleyball led me from a T3i => 60D => 6D

The difference was amazing on the last step to the 6D. I am impressed that a crop frame does that well. Here is a couple of examples the other day from a 6D. These are at ISO 10,000

My point is that I am very impress to see the 7D mk2 do so well. FYI, the gym above is a well lit gym as far as Jr High goes. I go to some of the schools and can't even pull my camera out because the lighting conditions are horrendous.

Nice examples
