[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]If you suffer from the idea that your lenses are misfocusing due to a body focus problem (for example Noctilux, and Summilux 75), you might check out http://www.dantestella.com/technical/flange.html When you do the math, you will discover that it is almost an impossibility that given the manufacturing specs of any M body, that the problem would be the body focus of the body (whether Cosina, Leica or Konica, even given their differing factory specs). Part 1 http://www.dantestella.com/technical/flange.html#dof addresses general issues of depth of focus and depth of field Part 2 http://www.dantestella.com/technical/flange.html#hexar and Part 3 http://www.dantestella.com/technical/flange.html#keppler addresses the interaction between the Hexar RF body focus spec and potential errors you can make in testing Hexar compatibility with Leica, Cosina and other lenses. Part 4 http://www.dantestella.com/technical/flange.html#summilux addresses the fallacy of the Summilux (it's the body's fault/lens's fault, etc) and the unnecessary work Leica and other rangefinder users have done on their cameras (body focus adjustments), when they should be concentrating on rangefinder alignment and more importantly, human factors.
