The 400mm Telephoto Lens Kit from Sirui bundles a lens whose focal length is equivalent to 400mm in full frame photography with a Mini Tabletop Tripod and Ball Head, a Cage, a Bluetooth Remote Control, and a Storage Case.
The lens, with its 400mm focal length and 8° field of view, will bring you closer to distant subjects. Its 11 optical elements in 9 groups have been built using German-manufactured Schott glass. The glass is coated with multi-layer, anti-reflective coatings for greater resolution, while the lens housing uses aircraft-grade aluminum for improved durability. This lens also features low distortion levels of 3%.
