<p>I just needed to adjust my D300. It was out by a lot. 40 cm at 3m on a 50mm f:1.4D lens.<br> There was not enough room to insert the Allen key again after I maxed it out. <br> What I did was use two Allen keys. I twisted the end of one so that it now has a ridge where the the other has a flat. This way one of the two keys will always fit, no matter what the position of the set screw is.</p>
