The Holga iPhone lens
is a nifty little device that snaps right to your phone like a case,
giving you 9 different lenses and filters with a simple spin of the
dial. I’m especially excited about the macro lens, which will work a
whole lot better than that built-in “zoom” slider bar that kills your
resolution. And unlike the photo apps with filters, here you can
actually see what the photo will look like before you click.
Just $30. Sweet. –Liz
