Great price, poor quality
purchased the 77mm version of this filter to protect my Olympus 300mm Pro lens. While I was doing bird photography in Ecuador, I had problems with this lens. All photos were blurry. I had used the lens 2 weeks previously and the images were razor sharp. 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 were razor sharp. So be very careful when using this filter at least on Olympus cameras and lenses. I have since put on a B+W filter and it works perfectly.
