The Tiffen 105mm Warm Soft FX 4 Filtercan be applied to create a warm cast over an entire image while purposely reducing the appearance of blemishes and wrinkles in portraits, or to apply a general soft-focus effect while maintaining overall sharpness. An array of small lenses distributed within the surface of this filter smooths fine lines and textures, which can be useful for creating a more flattering result of a subject.

The warming effect of this filter can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. This filter's overall coloration reflects a mired shift value of +45.

This filter has a grade of 4. Grades of 1/2, 1, 2, 3, and 5 are also available where this filter type's effect becomes approximately twice as strong with each grade number increase. When higher grade numbers are applied, a halation effect around highlights can be created to further enhance a subject's appearance or produce a desired effect.

This filter is constructed from optical glass for clarity as well as color fidelity. It is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 7. To be honest I have not researched lens composition. I read about this filter in a magazine many years ago and now have one for every lens. Does it make a difference? I have always assumed the lens was glass. As to light loss, I agree with another response and have never faced major light loss. If used in daylight it has never altered stops. Further, I would agree that light loss would be almost nothing to maybe 1 to 1.5 stops although the latter seems rather extreme. Not sure what you are looking for to render a decision, but I would never be without this lens, especially in the fall and doing landscapes/mountains.

A: I am 73 years old, have had one since they first came out. Now I have four.C.B.
