I have an issue for some time now where images I shoot at 200 mm at 2.8, 4, and to some degree 5.6 are blurry. They are not out of focus, but the images have a soft, blurry quality to them. I suspect the only way to resolve this is to send the lens in for repair, but was wondering if anyone else had similar issues and has a diagnosis. I have attached a sample image. Thanks

What focus points are you using?
Does this happen if you set the camera to P mode and One Shot AF?
What if you switch off Image Stabilization?

You deleted all the EXIF data so I can't tell much about your settings but the side bar indicates you used Ai-servo. Turn it off for a shot like that.

That is a screenshot, not a sample image. But, at least we can see the EXIF data ... and then some. Does that say you are zoomed in 1:1, or 100%? Have you been pixel peeping?

ebriggs1 - It is difficult even for me when looking at the image on my LCD screen or computer screen to tell whether the image is in focus or not, but when comparing the image to others that have truly been out of focus, I can assure you this particular image is not out of focus. A series of several images of this moment all exhibit the same characteristics. And I’d have to counter that in this particular situation where a subject is walking towards me, which he was, AI-Servo really is the appropriate AF setting.
What shutter speed were you using? When an entire picture is blurry but not OOF, it's usually because of camera movement.

What is really confounding is that there are some situations where the images are perfectly sharp. Here are three screenshots, zoomed in, showing three different apertures.
