City streets, old buildings, and interior spaces have been my favorite subjects with it so far. The broad field of view makes it much easier to fit a whole scene into the frame without constantly backing up. I especially appreciate how useful it is when there simply is not much room to move around.
Handling has been better than I expected for such a wide zoom. The controls feel straightforward, and I can change focal lengths quickly when moving between a large landscape and a tighter architectural composition. It also balances nicely on my Micro Four Thirds body, so longer walks with it have not been a hassle.
At the widest setting, perspective becomes part of the creative process. Lines near the edges can stretch noticeably, but I have found that useful rather than distracting when composing deliberately. Stopping down has also given me plenty of detail across scenes with buildings, trails, and larger groups of people.
Focusing has been dependable for my everyday photography, including moving between near and distant subjects. For video clips, the lens has been easy to operate without making the camera feel awkward. The broad view is especially handy for recording in tighter rooms or capturing a sense of place while traveling.
Low-light scenes have been a little more demanding because of the f/4 aperture, so I pay closer attention to shutter speed and ISO when daylight fades. In good light, though, the lens has been a pleasure to use, and the constant aperture makes exposure changes through the zoom range more predictable.
Most of my use has been for landscapes, architecture, travel, and indoor scenes, where the focal range earns its place in my bag. It has also encouraged me to experiment with perspective instead of relying on more conventional framing. For my style of photography, it has become a dependable and enjoyable lens to reach for when I want to capture a lot of the surroundings in one frame.
