Sometimes this is the only lens that captures the scene as I see it.

Got a quick question on this lens ... I know this lens is MF only, but for street photography can I just set the focal length to say 2m and leave it at that? Or do I need to manually focus the lens all the times?

If you set the aperture to 5.6 and align the " ¬8 " (infinity) mark on the focus ring to match the " ¬3.5 " mark on the aperture ring, it should be what is called hyperfocal, having everything from maybe 0.25m to infinity in focus.

If I'm wrong, I'm sure someone will correct me! ;)

If you set the lens for hyperfocal like BosseBe writes and turn on focus peaking, you'll have a reality check that I find helpful/comforting.

Exactly this.

The picture below was taken I think at f5.6 focus on infinity. Anything from more than about 25cm to infinity is in focus.

I haven't used this lens that much. Tried some more test shots today, as I am still learning to find interesting compositions with this focal length. I am slighty disappointed with the sharpness. I know about the problem with infinity focus on some copies, so I set the focus ring slightly in front of the infinity mark. Is this amount of sharpness expected or am I doing something wrong?

I tried defishing in Hugin using the Panini projection, not entirely succesful though.
