This makes a huge difference for close-ups. This is a standard four thirds lens (not micro four thirds), which I use with a micro four thirds-to-four thirds converter, on an EM-1 body, and all controls work perfectly (i.e., auto focus and other controls). The quality of the photos is excellent, too.

Broke down after very few uses, would not focus. Sent for repair at Olympus came back with the same fault, returned to Olympus for second repair lasted two shots, gave up with this very poor lens.

You do not need any extensions to get 1:1 (life-size) magnification (equivalent to 2x on a 35mm camera). You can bring this compact lens everywhere, and enjoy taking close-up pictures in your daily scenes, such as, flowers and insects.
