I recently purchased a used SAL35F18 that seems to have a "sticky aperture", i.e., the aperture doesn't close fast enough resulting in overexposed shots. It seems like a pretty open and shut case, however, the aperture appears to spring shut quickly when it's not attached to a camera. Has anyone ever seen this happen with a newer lens like the SAL35F18, and if so, was it just a faulty lens or something else entirely?
Here's a video of me pressing the DOF preview button repeatedly with the SAL35F18:
For comparison, here's my Tamron 28-75 F2.8 doing the same thing:
