Except for the band I haven't gone anywhere this past week or taken any pictures.
Spent my time building some photography gear but haven't gotten around to shooting those, either.
So I thought I would take some pics in my yard, and finally get around to using my polarizing filter seeing as how I've been able to put it on my new lenses for months but never have.
The dark corners are less about the CP filter and more about my lens--I have noticed it before, and really don't care much.
So it darkens edges and corners--big deal.
With 10.2 megapixels, you have some room to crop dark corners if they bother you.
