So i was walking past my dresser, my elbow caught my camera strap....fun...ground lens immediately released from body. so taking a closer look, one of the tabs on the lens broke off. It clicks into the body but is a little loose on the bottom. Can i replace the metal mount. Its a spherical 28-80mm lens. this sucks because i have a roll due in two days, I do not want to have to use my 300mm.
