AF-calibration for lens

[frode_inge_helland]

<p>My Zuiko 4-5,6 70-300mm is one of my two preferred workhorses. It is very sharp, but do not always hit the mark.<br>

An animal photographer wrote in a forum at Depreview that he did “lot of AF calibration of his 70-300 on his E-30”, and the lens got considerably more quick and accurate.<br>

I do not find anything in the manual about this.<br>

But I found this<a href=":%20http:/forum.fourthirdsphoto.com/f2/e-30-autofocus-adjustment-tutorial-50109.html">: http://forum.fourthirdsphoto.com/f2/e-30-autofocus-adjustment-tutorial-50109.html</a>, a button press sequence. But it is not clear what exactly is calibrated, if test cards were involved etc. and the effect of the manipulations.<br>

If somebody do know about this, I would be happy to know how to improve the AF properties of my 70-300mm on E-30.</p><div></div>

You may want to look into LensAlign. I just got done helping my wife use it to look at the AF calibration on her (Canon) camera. Fairly straight forward to use. You may want to take a look at it. Hope that helps.<br>
