Canon EF 400mm f/2.8L IS II USM ultra long focus lens

Canon's 400mm F2.8 lens was born in 1981 and is the most representative lens in Canon's New FD system that showcases Canon's technological strength at that time. It can be said to be one of the lenses that laid the foundation for Canon's modern DSLR ultra long focus lenses. F2.8 has excellent image quality even when the aperture is fully open, and does not change the lens length when focusing, with good handling performance. The New FD 400mm F2.8L lens adopts an 8-group 11 piece structure, 9 aperture blades, a volume of 166mm x 348mm, and a weight of approximately 5350g.
