edge of the lens (F 8, 50mm). Focus on
the program wheel of the camera.
A nice lens, I came
across it by chance and for cheap. At F 4 it's soft at the edges, but
gets much better when stopped down.. It
has good capabilities of close focussing for
such a wide lens. Carefully aligned there
is no distortion. The focus range isn't
bad for street photography.
