If you are using the correct hood (#12585)-- plastic or metal, German or Canadian -- there are two push-buttons on the front of the hood that you push as you put the hood onto the lens. When you release the push-button into the ridge on the lens, tiny knife blades inside the hood go into the ridge on the lens and hold the hood firmly on the lens. You store the hood on the lens by reversing the hood, pushing in the buttons as you move the hood into the lens's ridges. If your hood is like that -- and still pops off -- your push buttons may have missing knife blades. You can adapt the hood you have to fit over the front of the lens by cutting a piece of red felt to fit inside the hood until the hood fits snugly over the knurled metal front of the lens.[Because the hood is plastic [and difficult to glue properly] you might first try self stick tape cut to size; that might solve your problem.] And, if you use glue, don't put the shade onto the lens until the glue is completely dry. -- bob cole
