Does my D800 have the left af issue?
First you need to see if you need any AF fine tuning, using the center AF. Only mentioning this in case you have not done that yet. Then you need to compare the left, right and center banks, using the VF. On that lens, at 24mm and 2.8, the left and right probably won't be a sharp as the center, but they should be consistent to each other. If the left is out of focus compared to the right, you may have the defect.
