Re: Voigtlander 50mm f/1 Nokton Review


Yes, it's closer: Focus is set at 2 meters. I understand it, the FC is zero at infinity and apparently caused by the FLE. This would suggest that FC is present also at 2m. However, it may be more difficult to see in this particular case. In any case, the user claims that it is mild.

All of a sudden, over at the Leica forum, there is a Nokton f/1 user who said that he thinks the reverse / outward field curvature is mild. I referred him to the tests that Fred Miranda shared in this thread, but then he posted his own FC tests that look like this:













To me, this suggests that there is sample variation at play, and that some lucky buyers may get a lens without the quite noticeable outward field curvature we have seen in images from many users.

Fred, what do you think?



That's a pretty close focus example. Fred's tests are all at longer distances, so the results could be different.
