Olympus 12-40mm f2.8 AF noise

[rouji4256]

I recently noticed a rattling/ticking sound during AF and zooming on this lens after getting my Pen F.

I did not notice this noise before but also am not sure if it was present before. I updated my Pen F firmware to the latest as well as left it in the drybox at 40% for 4 days if it helps.

May I know if this sound is normal because I can't find anything useful online.

Just sent it in, will update when I get it back.

Got it back recently, having issues with infinity focus at 12mm when MF clutch is engaged now, will send it in again.
