for comparison. Focus is on the satellite
dish to the right of the big solar panel near the center of the photo.
Closest focus is 18cm from outermost edge of the lens, F 8. Focus on
the program wheel of the camera.
This lens is very small and very lightweight. However this one is not
at it's best with digital sensors, it is not as sharp as one could
imagine. It produces wide images with a nostalgic
image impression. Carefully aligned there is no distortion. Wide open
it's a bit soft. At F 8 it's nice,
focussing is very easy because of the wide depth-of-the-field range, at F 22 however it's blurred
due to diffraction. This is a problem of the APS-C sensor size, not the
lens (see comparison page).

There is a new version III of this lens, made for full frame sensors,
but the new one is much bigger and heavier, hence less attractive.
