70-300 DL Sigma Macro Zoom lens element loosened, and then reset

I sold a lens, shipped it, and the buyer heard a noise, a piece of glass, lens element had loosened. When I got it back, i simply rotated the zoom and the element reset. Is this possible/normal?

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

If it doesn't turn correctly, that strongly indicates you didn't reassemble the lens properly. Take it apart and try again. And I hope you have a lens collimator and other tools to ensure you get the lens elements aligned properly.

Trouble focusing with sigma 70-300 DL macro super lens


It will not focus on anything closer than 5 feet.

(From Sigma lens literature)
Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing distance is 1.5m / 59 in. at all zoom settings.
