special effects

This is a high end filter. Very well made. Glass with metal ring. Great for preventing damage to your expensive lenses and even filters out UV rays. Easy to clean as compared to cleaning finger prints off of a lens. I had dropped a lens and broke the filter, but the lens was unharmed thanks to the filter. Replacing the filter was far less expensive then replacing the lens. A great value for a high quality filter. No lens should be without one.

A UV filter or a neutral-density filter is the best way to protect your lens from dust, fingerprints, scratches, and so on, all the time, since they can be kept on the camera at all times. The UV filter will also help with haze a bit, since most haze occurs in the blue area of the visible spectrum, and UV is just below that in terms of wavelength.

I use a UV filter on my lens to protect it because unlike others it has the least effect on the amount of light passing through it and does not affect color. I use it indoors and out with both black and white and color films. The only time it is off of my lense is when I want to affect color or contrast by using a special filter. It reduces haze to improve the clarity of outdoor pictures. Tiffen filters are well constructed.
