Great for places where you can get a great foreground, middle and background elements or cannot back up enough.
Optics are great as is the build, its a tank.
The short zoom can be an issue but only time its been a concern is when I need to switch lenses to take a portrait.
The lens is sharp at 11mm f/2.8 to 16 f/2.8 but resolution peaks about f/4 to f/5.6. My copy is not soft at f/2.8.
There is barrel distortion at the wide end, but is mostly fixable. However be aware some remains. No issues in places like the Colosseum in Rome, or of a lighthouse. Photograph of a door will leave the picture somewhat distorted, note that you have to look for it.
Its my go to lens in European cities and places where I choose to fill the frame. Have shot everything from Rockefeller center, the Colosseum, Cinderellas castle in Disney, to Trajans column. Detail and rendition are stunning. It is a lens that I am keeping in my DX arsenal.
