- The lens is NOT equipped with powerzoom. GREAT! In my mind, powerzoom is primarily for videographers. I want the tactile response of a manual zoom. In fact, it's one of the very few tactile controls left in still photography.
- The size is very nice for such a wide zoom. While it doesn't have the shallow depth of field of it's equivalent field of view 24-70 lenses in full frame 35mm format, it is tiny compared to those beasts. dpreview indicates that it's best balanced on a camera with a grip, like the DMC-G3. Again, GREAT!
