So, I took it out over my lunch break, and tried to come up with a better way to describe what I'm seeing. It's not streaks so much as some spots in the patch. They are really hard to see, and again, only noticeable against a bright white surface.
So you think this may be a sign of delamination.
In my previous camera, I guess it was the mask that had the issue (cracking) and neither Youxin or DAG could fix it. But in this case, is it a mask issue or is it something that is resolved by recementing the main prism?
