This lens came quickly and looked to be in very good condition. However, when I tried to move the zoom in and out - it stuck! Movements were sticky and jerky when any zoom in or out was made. I checked online and discovered that sticky zoom lenses are not uncommon - but not in "new" or "certified/refurbished" lenses. The causes for sticky lens are either out-of- round housing or lubricating grease that has hardened with age. Neither of these should have been a problem with this lens based on its advertised description. I was disappointed and simply returned it through Amazon.
