Closest focus  is 85cm from the outermost edge of the lens, F 8. Focus on the program wheel of the camera.

This is a very sought after and often quite expensive lens for Paxette cameras, it has a 
15 blades iris and it's luminous. Wide open it's (too) soft, at F 4 it's fine in the center, but it stays softer towards the edges. At F 16 it only gets a bit blurred due to diffraction, but better than other lenses. This is a problem of the APS-C sensor size, not the lens (see comparison page). The lens has no close focussing capablities. It is very small and extremely lightweight, particularly for a F 2 lens. A lens which offers 1 stop more than standard. It would be a good portrait lens on the A6000.

The M39 Paxette Mount is the same thread as ordinary M39 (Leica), but  a different flange focal distance. Please refer to the Paxette lens page.
