amaizin, That's not really normal, because you might only normally hear a tiny noise if you shake a lens not mounted on the camera, but not loose glass sound, everything is fixed and solidly set for alignment when focusing if any element is loose it could never be able to get a clear focus and the element would be so scratched there would be all kinds of distortions even if it went "back into" place. You'll hear loose glass after you drop a lens on to the sidewalk or hard surface and an element is dislodged. Inspect the lens body for an impact mark a lightened portion in a ring shape where the metal or plastic has been stressed or the telltale signs of an abrasion from something like a hard rough surface such as concrete (a little group of pin **** on a corner). The lens should be inspected by a reputable shop to determine if it needs to be repaired or replaced. I take it that you were selling it to upgrade to another lens or other equipment. randy320sgi

There is a ring you must remove then you will have to soften the silocon we use aceton but you must be very carefull DONOT lever out the elemet just turn over the lens and bang it on the table a few times and the front element will fallout with luck
