F 4.5.

F 8.

F 22.

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).

It delivered beautiful images on film with a Bessa L. 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.
