A lens with a good wide-angle coverage (say, 24 mm) will allow you to include more of the picture in the same one frame. To contrast, a panorama picture needs many frames to cover the same angle of view.
The APS-C sensor means better wideangle coverage in comparison to Micro Four Thirds; a 24mm lens behaves like a semi-wide 35mm, rather than a 50mm normal.
To improve image quality Kodak introduced a camera with two lenses, one for wide-angle coverage. Shooting down on these two girls makes their heads look much larger than they really are since they are much closer to the camera and its wide-angle lens.
A benchmark in Canon optical technology, the lens supports 24mm ultra-wide angle coverage for shooting horizons and landscapes, and an extended 5.0x optical zoom for zooming into distant scenes or subjects - all while offering a bright f/2.
The three things I require of a strobe for shipwreck photography are (a) quick recycle time because we are working at depth and trying to stay ahead of the turbidity generated by other divers and ourselves; (b) wide-angle coverage; ...
