Re: When extreme high ISO is better than nothing: a rundown on my experiences shooting ballet

You do not NEED high ISO in camera to get faster shutter speed. If you take a picture of the same scene at at 1/160s f/3.2 ISO12800 and 1/160s f/3.2 ISO100 and then bump +7EV in PP you'll get same picture with same SNR. (This will work with cameras, which have ADC with constant read noise, K-5 does have constant read noise).

For the camera itself, amount of noise depends only on the quantity of light your sensor gathers, which is determined only by shutter speed and aperture size. You can see example here or just try it yourself.
