Hey folks, I just got a Voigtlander 35/2.5 Skopar VM (the M mount one) and I can see blobs of grease at the back. Is this expected? I'd normally send it right back but given the tiny size of the lens and the fact that basically the lens is the mount thought I'd check. The grease is in the helicoid, not running off anywhere else and everything work perfectly but I still found it weird. The lens is used but basically looks unused.
