I had to re-upload this album with cropping the pictures cause i didnt like the sight of the cokin adapter on the sides. I found out that the cokin lens adapter, eventhough it doesnt slide on the fisheye's lens, fits perfectly on it and with some tape u can secure it on. The difficult part was that ,as oppose to a circular filter that seals on the lens and prevents light coming in from the sides, this one let tons of light to come in from the top. Anc ombined with the f/8 of the fisheye, it made it extremely difficult to calculate exposure times.
