Great price, bad quality
bought the 77mm version of this filter to protect my Olympus 300mm Pro lens. While doing bird photography in Ecuador, I had problems with this lens. All photos were blurred. I had used the lens 2 weeks earlier and the images were crisp. I had to throw away a whole day's work because every picture was bad. I put the lens away for the rest of the trip thinking the lens was going bad. I got home and started testing the lens. I noticed that with the filter, all the images were blurry. So I removed the filter and all the images came out crisp. So be very careful when using this filter at least on Olympus cameras and lenses. I've since put on a B+W filter and it works flawlessly.
