14mm calibration and Nokton aperture breakage

Last month I was using my Leica at MacWorld when all of a sudden the aperture started to behave weird. For some reason a blade inside the thing seems to have broken lose from it’s mount and pushed the others around. Now, at maximum aperture the lens looks like this.

This is a limited edition Voigtlander lens. Only 300 were produced in a chrome body.

I don’t have my flash around so I had to hack a front light together using my Litepanel in order to make the aperture blades visible. It was running low on battery so I had to remove the warming gel which destroyed teh color balance. I didn’t know where to place it to reduce reflections off the glass surface. (I have better placed shots, but they were misfocused.)

The postprocessing was just done to balance the lights and bring out some of the definition and detail in the aperture.

The change in saturation 1/3 of the way down is a bug in Aperture 2.0 export. The correct color/saturation is the top 1/3. It looks fine in the previews.

  1. wow nuts. I’ve never seen that. Oil on the aperture blades for sure, but not brokeness.

    How do you find the macro performance of the 70-200 with the canon close up filter?

    As for the reflection. Looks like this lens doesn’t have that good of an anti reflective coating. I think you would need two lights sources to get this right. One further up and away from the lens to give the lens body some light. Then a smaller, weaker light head on to illuminate the aperture blades.
