Isn't that an 80-200?? If it is it's built like a tank.
I've shot some great interview stuff with this series of the 80-200. Design inspired by their Mk I 28-70 whose design was licensed from Angenieux. Still have a mint Nikon mount one and still use it occasionally on the FS7 with a Speed Booster. It then becomes an awesome F2.0 80-200. A great $$$ value lens. The fact that they are parfocal makes them great for video work.
