This lens is in great condition, the only thing is sometimes my Canon 1DX mark ii has issues with communicating with the contacts of the lens. It's strange, because the lens does work, just not reliably as it does force me to shut the camera off and re-attach the lens. However it doesn't really matter for video, as when I pair on a Canon C300 Mark II it works without a problem ever. So I would only really reccomend this purchase to people using it for video and not photo.
