You are at high ISOs now at f/2.8. With an f/4 lens each of those shots would be at a twice as high ISO, unless you adjusted camera settings.

12K-20K ISO is probably pushing acceptable noise limits.

"12K-20K ISO is probably pushing acceptable noise limits."

IMHO, I would not accept any ISO that high.    Not even close as 1600 or possibly squeeze out 3200 in a pinch but nothing higher.

You said,........

"The majority of the shots were as follows:
6400 - 4.0 - 1/500 - 70mm
5000 - 2.8 - 1/800 - 70mm
5000 - 2.8 - 1/640 - 70mm
10,000 - 2.8 - 1/400 - 70mm
10,000 - 2.8 - 1/640 - 70mm
8,000 - 4.5 - 1/640 - 70mm
2,500 - 2.8 - 1/400 - 70mm
10,000 - 2.8 - 1/800 - 70mm"

Looks like 70mm is your focal length of preference.  May I suggest a different course?

The Canon EF 85mm f/1.8 USM Lens.  Much faster and much lighter and much much cheaper. Plus is is as sharp as a lens can be. In fact you could have a couple of these faster prime lenses for what one 70-200mm f2.8 costs.  You will love how much lighter they are and easier to handle.

Thank you for your input! 

It is always at 70mm cause I needed to zoom in more and it still wasn't quite enough.

I will definitely look into this

Thanks again!

Do you mean zoom out? If you need to zoom in, it would have been 200mm.  I second ebiggs' suggestion - an 85mm f/1.8 will do or for roughly the same price with a 70-200mm, you can get either a newer 85mm f/1.4L IS or a 85mm f/1.2...they are way faster than the 2.8 (2 stops or more).

I think it is time to learn how to post edit.
