Just picked up a m4-p for a reasonable price and the exterior and everything is very clean and I’ve shot 3 rolls and it’s came back sharp and focus is accurate as well as shutter speed tested( local shop said it was CLA’d about 10 months ago). But today I noticed what people described as balsam separation or desilvering when I looked at the front of the viewfinder. I just want to also say that I didn’t notice it and it does not affect my patch or my visibility in shooting. Guess what I’m asking is this seems minor? Should I just keep shooting with it until it gets worse or starts to come into view of my shooting? Does anyone have this and have they noticed it worsen over time?
