<p>Hello there,<br> I've been struggling with this issue for two days now, and I'm kind of giving up on it.</p> <p>Got D610 + Tamron 24-70 + Nikkor 80-200 2.8 (two ring).</p> <p>A few days ago, i shot some studio portraits with the 24-70, and got some front focus on it, so i decided to do the af fine tune, as i've done in my old DX days with other bodies.<br> Printed the <a href="http://regex.info/blog/">Jeffrey Friedl's Blog</a> charts, and started to do the test.<br> I was very careful with the setup, as i've always done.<br />Got wrong results every time, so i guess I'm doing something wrong.<br> I took a shot at "0", then at "+20" and then at "-20". The results were almost identical. <br />I double checked i had the AF tune in "ON". Wasn't using LiveView since i read it won't work with it.<br> This was with the 24-70, since it was the one with the front focus problem. And i just repeated the test with the 80-200 just to check, and still the same.<br> Would it be possible there are lens (or bodies) that won't respond to this test?<br> What am i missing?</p> <p>Best,<br />Luis.</p>
