Item Description
Sigma 2x EX DG Tele
Converter
The TELE
converters provide a larger focal length and allow greater mobility, which is
useful for taking photographs of sport, nature and landscapes.
The 2 EX is placed
between the lens and the camera, and it allows the photographer to use the
70-200mm f/2.8 lens as a 140-400mm f/5.6 telephoto zoom lens, and the 300mm
f/2.8 lens as a 600mm f/5.6 ultra telephoto lens
