This is a nice telephoto lens for Canon FD cameras. Note that this lens will not work on any modern camera without an adapter. It would be an excellent lightweight telephoto for a classic FD kit or adapted to mirrorless.
This one is in good condition with moderate wear. There is a tiny mark on the front element that I could not see without a flashlight, it's minor and it won't affect your image quality on a lens this long. Otherwise the glass is clean with no haze or fungus. The focus and zoom are smooth and the aperture is dry and snappy.
