The Sigma 24-35mm F2 covers a full frame (24mmx36mm) sensor and maintains a constant aperture of f2.0 throughout the zoom range.
The lens is also internal focus and zoom, so the lens stays the same length at both its widest, and longest focal lengths.
Typically professional zoom lenses feature a maximum aperture of 2.8, so this lens is an innovative addition to both photographers and film makers.
A great choice for reportage photography in low light.
