Its 4x ultra-telephoto zoom capabilities, with a focal length range from 150mm to 600mm, enhance the creative potential of telephoto photography, a captivating feature for all photographers, particularly nature, wildlife, and sports shooters. 4x ultra-telephoto zoom lens with a focal length range of 150mm to 600mm The focal length range of this lens was extended by 50mm on the wide-angle side and 100mm on the telephoto side compared to the existing model A08, making it possible to take even more striking photographs of birds, wildlife, sports, and other distant subjects. Mounted on APS-C DSLR cameras, it has a stunning near1000mm telephoto equivalent focal length range of 233mm to 930mm. World class image quality Employing 20 elements in 13 groups and boasting an advanced optical design, the lens delivers a superior balance of resolution and contrast for sharp, clear images. The front group contains three LD (Low Dispersion) glass elements (two in the first group, one in the third) for enhanced optical correction effectiveness, enabling the lens to thoroughly compensate for on-axis aberrations at the telephoto end. The lens also adopts eBAND Coating, developed from state-of-the-art coating technologies, and conventional BBAR (Broad-Band Anti-Reflection) Coating to greatly suppress ghosting and flare even when shooting under adverse lighting conditions.
