Hello, everyone! I recently bought a K3 on ebay and just finished getting my second roll scanned. Unfortunately, a lot of what would have otherwise been some nice footage came out unusable because of a very strange issue. Here are a couple clips that demonstrate the problem: Basically, at the start of a shot, the film will weave in and out of focus (there are always a few frames at the start of a shot that are in perfect focus) but then the film settles in a position where the center of the frame is blurred, while the sides seem to be in focus. I had only noticed this issue in a couple of shots in the past so I wrote it off as a one-off thing, but it was happening a lot with this last roll I shot. From reading this post from 2008 which describes the exact same issue, (only with an Arri 16S) it seems like the pressure plate just isn't holding the film flat enough, and I need to either replace the current pressure plate spring or tighten it. In some other threads, I've also come across people mentioning that they have tightened the pressure plate spring on their K3's, but I'm having a lot of trouble figuring out how to do that. Does anyone here happen to know how I could make that adjustment with my K3? Do I maybe need a new pressure plate in general?
