Negative Positive
Title: Mixed results
Review: I have had one of these filters on my Nikon 18-70mm DX lens for a couple of years and had no trouble with it. So I let Amazon add one to my order when I bought the Nikon 70-300 f/4.5-5.6 VR lens. The filter ruins the performance of the 70-300 VR, the lens doesn't focus correctly and there are strange reflection patterns in the out-of-focus areas of the image when you zoom in to 100%.
Is the review positive or negative?
