Excerpt: A Circular polarizing filter gives you the option of adjusting the degree of light to be filtered without changing the layout of the camera.(i.e. horizontal to landscape and vice versa) A simple a simple rotation of filter can change a hazy sky to blue without distorting the color. I'm a little apprehensive about the thickness of the filter, but there is no question about the results.
Pros: Clear Optics, Consistent Effect, Easily Mounted, Firm Mount
Excerpt: Used for 70-300mm VR, when needed. (B+W UV is the always-on protection filter)Adequately strong polarizer effect, front piece easy to rotate yet still not too tight.Anodized Aluminum frame feels less sturdy than B+W's brass frame. Sometime it is difficult to dismount. I have not had the need to clean it yet so don't know how easy it is to clean the filter without leaving liquid marks.
Excerpt: Highly recommended accessory for shooting outdoors in bright sunlight. It is a 'Must' accessory. Colors are move vivid, reflections are decreased and detail is better. I'm going to get one of each size to match my lenses.
Excerpt: This Nikon 67mm Polarizer II filter uses optically flat glass that does not add much aberration to the photo. Here is the Southwest where we have lots of sunshine, it is sometimes important and when the light is just right, the polarizing filter is a must. I hope the 72mm Nikon polarizer is just as good because I need one for another Nikon lens! Also, this polarizer will allow for about 1.5 f-stops of light attenuation if required. I just like Nikon quality!
Pros: Clear Optics, Easily Mounted, Firm Mount, Strong Construction
Excerpt: I am very happy with this polarizer. It is thin enough that I can use a Lee filter holder with wide angle adapter over it on my 16-85 lens with no vignetting. I have tested it on my lens and it seems to have no effect on sharpness. Does what a polarizer should.
