Focused but still hazy

For some reason my my pictures have started looking hazy in every shot. I have not changed any settings in the camera other than changing from:
Case 4: 0,0,1
to a:
Case 2: -.5,0,0

Each picture has the center focus point on chest or face of the player yet zooming in 1:1 and it looks hazy or blurry for some reason.

Any idea how to fix this?

Thank you.

i forgot to add the camera details:

Canon 5D Mark III
300mm Sigma f/2.8 lens
Fstop: 2.8
Exposure: 1/1000
ISO: 1000
EV: +1.3 Step
Shutter Priority
Manual White Balance
No Flash
2 Gel knee pads :)

A few observations. A higher ISO might work better than exposure compensation. Also, tighter framing might relieve the "hazy" look.

And you might want to make sure the lens' rear element is clean.

I agree about trying to shoot tighter so you don't have to crop so much.

Don't know much about that Sigma lens. Have you micro-adjusted the focus? I know Sigma is producing some nice glass these days but I am still not sold on the AF of their lenses, especially for sports/AI servo.

Details on what these are would be nice, from someone who doesn't have a 5D III:

Which Sigma 120-300 version are you using? (DG, OS, Sport?). I would say that if all of your shots are like the ones above, then your issue is about 95% likely to be due to shooting much too wide. Very few lenses can still look good when you are cropping so heavily. I used the Sigma 120-300 DG lens for a few years, and while a fantastic sports lens (with some AF quirks), it wasn't necessarily the sharpest lens I've ever owned. When you zoom in to view 100% crops, things due end up looking a little 'hazy'

It's also harder for the AF system to absolutely 'nail' focus when the subject is loosely composed in the frame.

How will these shots look @ f4...@ 2.8 wide open you might get that hazy look...with a 300mm or other lens..
my sigma 70-200 2.8 is the same hazy but @ f4 it looks great... take a few @ f4.. then recheck..

good luck.

With the 5D3 these are specific adjustments for tracking sensitivity, acceleration/decelerat​ion, and AF point auto switching.

In these shots have a close look at the grass for a sharp plane of focus. If there is grass in sharp detail is it in front or behind the cleats. If there is no sharp grass you have a blurry lens.
