Sorry to be so blunt. But why would you have to post a chart picture that clearly shows a out of focus left sensor and ask what we think. It is old news that some sensors have a left focus problem. If you need people to tell you what they think about the left focus issue just TYPE IN THE SEARCH BUTTON IN THE RIGHT CORNER OF THIS PAGE " D800 LEFT FOCUS ISSUE". You will get everything you need to read about what people think about the left focus sensor. Good luck

Brosen, Thanks for the post.
The left focus does appear to be off.
Can you explain how you did the test a bit more? Were the 3 targets lined up side by side on a wall? Or did you have a single target that was shot with the individual center, left-most and right-most focus points? Did you rerack the focus before each new shot? Also, where did you get the test target used for the test? Is it downloadable from the Internet?

With all due respect, I do not see any entries in your profile. Could you please fill out your profile if you don't mind? This perhaps would add more credibility to your claim. As another colleague states, it is clear that the left focus is soft, so why do you ask others for their opinion is kind of strange. If I were you, I would send the camera back to Nikon with these samples for them to take care of this situation. It is old news at this point that there D800/D800Es with focus problems. However, there are many of us fully satisfied with our camera right of the box. Respectfully, I am going to give you my humble opinion. "Send the camera back to Nikon".

Just as a clarification, I was looking for feedback regarding how bad it is based on the experts opinion, I am not one. From my personal perspective it's not that bad in order to return it or send it in for repairs, I can live with it.
Something interesting that I discovered today, when I took the pictures I had enabled Light Optimizer and Lens Correction (something like that), I did new tests today with those parameters disabled, and the result are much better, I am going to post those photos later today.
Thanks for all the feedback.
- The test was done with a D800 S/N: 3043XXX - I've tested with other lenses 50 f/1.8G, 85 f/1.8G, 105 f/2.8G and the results are much better with larger focal lengths. - I used 3 targets, one per each focal point - I've done the test multiple times using a controlled environment with a tripod - At larger focal length I would say there is no visible problem (human eye)
