Ultra Wide-Angle lenses
Architectural photography also includes pictures of interiors. Often the areas that need to be photographed are narrow or small, but need to be shown in their entirety. This calls for another breed of special lenses. Ultra Wide-Angle lenses, like TS lenses are expensive playthings for people who have no need for them, but a necessity for those who do, 14-21mm prime lenses fit the bill for professional photographers who make a living out of photographing interiors. However, for the enthusiast who prefers to have a more usable range of focal lengths and does not 'need' the ultra-high quality that the prime lenses offer, the ultra-wide zoom lenses that various companies offer are a good option.
