Hi, Hoping someone can help provide some insight. I bought a second hand 16-55 f2.8 from wex. The camera functionally focuses fine, the zoom is smooth, aperture click is as expected, and so on. The only thing I’m not sure about is a chirping the lens seems to make when focusing. My question is, is this normal or is this something I should be concerned about? FullSizeRender.MOV
