— for a lens designed for shooting buildings, it is almost mandatory to have a tilt-shift mode (see "Functions / Capabilities"). This mode allows you to eliminate the curvature of straight lines that occur when shooting high-rise buildings at close range (these curvatures are not critical for amateur photography, but are unacceptable in professional architectural photography). The focal length in "architectures" is usually constant (see the relevant paragraph), but its value can be different: in this category, there are both wide-angle optics and models close to telephoto lenses.
