Specification :
The 50-200mm F2.8 IS PRO is the world’s only fully weather-sealed, all-purpose super-telephoto zoom lens, offering a 100-400mm equivalent focal length with a constant F2.8 aperture (as of September 2025). With the optional MC-20 teleconverter, it can be extended to an 800mm equivalent focal length. Weighing just 1,075 grams (2.37 pounds), it is built for versatility. Paired with our advanced 5-axis sync IS, this lens supports agile handheld shooting with up to 7.0 stops of image stabilisation.
Built to withstand challenging conditions, the lens features IP53-certified splash- and dust-resistant, and freezeproof construction for reliable performance in the harshest environments. Its 0.78m minimum focusing distance makes it ideal for capturing stunning close-ups of delicate subjects with up to 0.5x magnification (35mm equivalent). Despite its impressive capabilities, it remains remarkably lightweight, making it easy to carry on long shoots or in remote locations. This balance of power and portability makes it an excellent choice for photographers aiming to capture handheld telephoto shots in extreme field conditions.
