Noise or Focus

This example of photo is from a shot. Is this noise or a focus issue. I used a lightmeter shooting at 250 iso 125/f3.5. Can someone tell me how to avoid this in the future.

Looks like your lens is front focusing, imo. It looks as though the wall just in front of your model is in focus.

I used the center point to focus? This is not the only photo that looks like this.

Your camera has definitely focused on the closer portion of the wall. You say you are using the center focusing point, does the camera hold the focus? You may need to change the drive mode you are using. Also, try changing the custom function that moves the focus button away from the shutter release button. I am not sure what that function is on your camera; you will have to look it up in the owners’ manual. Try that and see what happens. Keep playing around with it until you figure it out. I see no problem with noise. Good luck.

It is a focus problem. Most are user generated. Not that it can't be hardware. You are using a fairly open aperture and shooting at a fairly long focal length? That will give you a very shallow DOF. If you waver a little, after you establish focus, you can have a problem. Try taking three exposures of the same shot and see if they are alike. If they aren't, it is you.
Better yet.... try a tripod and shoot an inanimate object. Then you will know.

This shot took place between 6pm and 8pm ct. A good portion of the shots are soft in focus. Could it be that the lens focus is off? I was using a 70-200 f2.8 ISL.

Sure...but more likely human error. I told you how to test it.
Auto focus has a much harder time working well in low light with dark surfaces. It needs contrast to work. Did you get the red flash of the focus point you were using? Her lower lip almost looks in focus to me. I really think it is just you struggling with shallow DOF. If you were shooting at a long focal length at 2.8, it was very shallow.

Yes flash point was lit. I was shooting at f3.5.

Better? I did no noise reduction.

Can't really tell because the up load image imo only good for view the flaw not editing cause I had to resize in MS Pic Manager. Cause I don't know how to resize in LR (Learning Curve).
