Hi Sony Alpha Forums,
I would like to ask. During startup/turning off the camera with Sony 70-200 f/2.8 GM lens attached, is it normal to hear a short rattling noise from the lens?
During auto-focus, the lens doing just fine. But when start-up/turn off, I heard a short vibration/rattling noise from the lens.
The noise is similar like the rattling noise when Sony Alpha is in self-cleaning mode.
From what I observe, it's a mechanism inside the lens which open/close the aperture.
Is this noise normal?
Looking forward to your advice.
