Professional ultra-telephoto zoom lens covering 200-400mm focal range at constant f/5.6 aperture, ideal for wildlife, sports, and distant subject photography. Features Low Dispersion (LD) glass elements to minimize chromatic aberration and deliver sharp, high-contrast images throughout the zoom range with excellent color accuracy. Includes built-in tripod collar for stable shooting and balanced handling of this substantial telephoto lens, with 77mm filter thread for standard accessories compatibility. 【Item Condition】 The item is in relatively clean condition. 【Functionality】 Operation has been tested and confirmed to be working properly. 【Optical System】 The lens has been inspected under strong light. There is some fungus present on part of the edge of an internal element, and slight fungus near the center area as well, but I believe this will not significantly impact shooting performance. 【Included Accessories】 Front cap Rear cap Please refer to the posted photographs for details regarding the item's condition and included accessories.
