Title: Good for protecting
Review: I only use this filter to protect the lens on my camera. It does that well. Make sure you do not over-tighten the filter!I did see some horrible ghosting effects of the filter but it was only an issue in low light with long exposures and bright subjects like neon signs. The light goes through the filter, reflects off of the sensor, off of the back of the filter and back into the sensor causing a double "mirrored" image (based off of what I read). People seem to make a big deal of this where I would simply say remove it.All in all if your lens doesn't have a lens hood, use it just for a longer lens lifespan.
