Nice article, and criticism where it's due. Even with the latest firmware, it's still certainly no auto focus monster. It rapidly gets more accurate once my subject starts being two meters away or more though. Portraits within 1-1,5 meters are unfortunately a weak spot, especially as turning the focus ring manually can be a bit tricky too, in the heat of the moment.

Still, it's very fun and brought back my inspiration big time. It's strangely liberating to be limited by the lens choice. And as long as you shoot macro on f/4 or smaller (no optical issues on f/2 in non-macro), it's an incredibly good lens too.
