    This lens has a two touch tele-zoom design that provides constant f stop and no change in focus when zooming. Minimum focus distance is 2m. 15 multi-coated lens elements in 11 groups. It's quite heavy for m43 but has a removable tripod mount. It has minimal high contrast flare at f5 that is completely gone by f6.3 (between f5 and f8 clicks). Sharpest images are achieved from f5 through f8.

    You can see the blue contrast flare on some of the leaf highlights around the base of the tree.

    Cool, havent seen many samples from this lens. Do you find it difficult to focus?

    Not really, it's smooth as butter. One nice feature is that once you have the focus set it stays the same even if you adjust the the zoom so you can easily change the composition on the fly.
