I have disputed with this lens a vacation and felt rarely longing for my other lenses. Clear: In the twilight it gets tight, Lichtsärke 4 is just far from extreme. Was striking, however, as the focal lengths fit for use: on a full frame camera 24mm already allow nice wide-angle shots and a bit architecture, and the 105 mm telephoto are sufficient in most cases. While it is a relatively heavy "Klopper", you can still carry on your own back through the countryside. Wildlife photography - Forget it. Macro: not really. Portrait: are more likely. At dusk: on the border. All in all, highly recommended to those who are on foot and want to have something else in your backpack.
