This reduces the risk of the lens mount breaking due to the lens weight. For primes, I understand that the nodal point will be fixed, so I could find the point once and mark it, but for zooms, since the nodal point moves when I zoom, a method that can be easily replicated in the field would be best. These figures correspond roughly with those from www.myfourthirds.com by Klaus Schraeder (this link appears to be broken now) for the 11-22mm lens on an E-1 camera when adjusted for the sensor plane distance. 30mm at F11, focus at aprox 0.56m, 0.5m at left f16 mark. endobj Why?
