Not as fast and not as quiet as my 18-105 whale! There is a catastrophic lack of a stabilizer ! At a shutter speed of 1/60, itβs difficult to shoot, this is after my whale, where it was easy to shoot at 1/35. You need to learn how to shoot with this glass and you can get very tasty shots! By the way, today there was a glitch - auto focusing refused to work after working in manual mode - I took it off, put the lens in - everything worked . Then there were no glitches during the day.
