<p>Ok so I saw that my AF points were smudged/smeared.I figured that it was caused due to the misalignment of the AF screen.I sent to the canon service center.They failed to repair it for the first 2 times. The third time they told me that all 600D/T3i models were like that.<br />I probably shouldn't try to repair it on my own since I will ruin it more.Now my question is will affect in any way the af of the camera or the picture quality?</p>
