Summary: I have the Nikon 18-70 lens and the HB-32 lens hood and I have had continual difficulty putting the hood on straight and when it stores in the inverted position over the lens it fits loosely. Due to the difficulty installing the hood for use, it frequently causes vignetting in the corners if you aren't checking the viewfinder closely and has also recently caused a large dark area in the bottom center of the photos.
Summary: This is the third one I have to replace as it is difficult to attach and easy to fall off. I haven't looked at the others, but i would like to know where nikon had them made. Product is not what I would expect from nikon. Maybe I am spoiled because I have had leica cameras before I went digital. The last one fell off today while I attended the French Quarter festival and apparently bumped into someone. Thanks for your time.
