Mixed performance

This is a lens that you both love and hate. First of all, it seems a little large for its range and aperture. It almost double its length at 16mm. The built-in flash would be blocked a little beyond 28mm. Centre sharpness is decent but corner sharpness could be better, especially for distant subjects like scenery. The drops in corner sharpness might be due to the average built quality, but then it is a very affordable lens for this range and optical performance. At close distance, like family snaps, pictures are really sharp. It is pretty flare resistance too. It is sharper at the wide end than the long end.
