<p>That Luminous Landscape article is wrong about the 8 element Super Takumar. The 8-element ("Planar killer" design) has no yellowing Thorium element. It is differentiated by that, the location of the infrared focusing mark (inside the f/4, not outside it,) and a pretty low serial number (don't know that I've ever seen one that started with over "150"). The yellowing Thorium element was the version after the 8 element, a 7 element design, still called Super Takumar.</p>
