My canon EOS R5 is taking slightly blurry photos

[Shaneradin]

hey all, I’m very lost and I really need help. I have a canon r5 with a 15-35 24-70 70-200 all lens are 2.8 rf. Whenever I shoot with the 70-200 or the 24-70 zoomed in my pictures are slightly blurry. Just to give context I sent canon my camera 5 times and they said nothing was wrong with it each time. The pictures are never under exposed and they are all shot at 2000 shutter speed. I really hope someone can help me.

Hi, you'll be asked to upload some examples and what all your settings were so folks can try and diagnose.

Ahh yes sorry here are a few in a good drive.

Hi.
I have downloaded your photos and my first question is why are you shooting at f/2.8 on a bright day?   It appears to me that your photos actually do have a point of sharp focus, but your depth of field is very shallow, so a lot of the image you would likely want to be in focus is not within that DoF.
Given have moving subjects and in some cases (e.g. the two players) , I would have gone with something like f/8 - you will still get a decent background blur but you will get more of the subjects in focus.
For example, in the following image, taken with a Sony RX-10IV, which is has a 1" sensor and thus an equivalent f/stop is f/10:  There is still good separate from the players and the grass behind, but the critical elements: both players and the goal posts, are within the DoF.

What kind of focus tracking, if any were you using please?

Hi, yes sometimes I bump it to f/4 but I like to stay at 2.8 to keep that really shallow depth of field. I’ve never had an issue with it before though. It was like all of the sudden my photos are blurry. My focus settings are set to track the eye of humans.

Well, looking at the images, the eyes are in focus for both individuals and for the chap in the black shirt but your other characters are not.  So, to me your camera is selecting focus correctly for one person, but with more than one, and such a shallow DoF, you are likely to get other people out of focus.
Do you shoot in RAW as well as JPG?

[Shaneradin]

I shoot raw. On pictures with only one person in them, if you zoom in there is a slight blur to the pictures. That’s where I’m confused about.

[Tronhard]

Could you please share the RAW images then.

[Shaneradin]

Unfortunately I do not have the raw images. Is there anything else I can do to help u help me?
