I got it on the Olympus E-520th 1. As a wide-angle (at 14-42) it comes from practically 28 mm to virtually 26/27 without edge - on down with the edge (quality no longer 100%). 2. As a macro, it is an affordable entry-level (but the edge has blur) Conclusion: 2 Flying priced applauded - but not kill 100%! (With the quality of smears you have to stop living - otherwise it will be expensive + heavy!) froentsch!
