First and foremost, if you aren’t at least a little Geeky, this post is not for you. Unless you’re one of those people who thinks ‘just take some pictures, dammit’ when I write some article about resolution testing. In that case, you might like this article because we’re taking pictures to test lenses. Sort of.
For the last 18 months or so I’ve been on a Holy Quest, trying to find better ways to optically analyze and adjust bad lenses. Why? Partly because we need to. Some lenses factory service just can’t seem to return to proper optical adjustment. Partly because some smug people several years ago told me I could never learn how to do that, which, of course, made me really, really want to.

Gaaf apparaat. Moet zelf altijd denken aan Dee Dee "What does this button do?" van het tekenfilmpje Dexter's Laboratory. Hoe die gedachten opkomt.... geen idee....

Wat doet dat stukje gereedschap (wit met hout) in de rechteronderhoek van de laatste foto (boven de kop "So What Does That Thing Do, Anyway?") Is dat op de laatste afstelling te doen?

OLAF’s Lens Art
http://www.lensrentals.com/blog/2014/04/olafs-lens-artThis is a Geek Article, with very little practical information. But there are pretty pictures that non-Geeks might like. (Not the construction pictures, the ones further down.)
