Query: Necessary but blurry on the edges.

This is a must have for doing any close-up or indoor footage. If using on a HD 1080 video camera then you will notice a little blurriness along the edge of the frame. If you have a lot of camera motion in your video it will not be too noticeable, it's mainly when the camera is static does your eye tend to zone in on it. Over all it's a good product.
