The Sigma 28mm F1.8 EX DG ASP Macro
The 28mm F1.8 EX DG ASP Macro from Sigma is a fantastic lens for shooting landscapes, architecture, weddings, and any low light situation.
This full-frame, fast-aperture, rectilinear wide angle lens is wide enough to be used in most scenic and landscape assignments as well as building interiors. It’s also useful when shooting large groups of people, as the wide angle effect and field of view is not as extreme as shorter focal length lenses – so it’s great for group shots at weddings or family events.
Even though this is a wide angle lens, it has the ability to close focus to 7.9 inches at a magnification ratio of 1 to 2.7, so you can make great macro and near-far effects in your wide angle shots.
