The Tiffen 138mm Mounted Low Contrast 1/8 Filter can be applied to purposely reduce contrast while photographing an image or while recording video. By redistributing illumination from brighter to darker areas within a scene, this filter is useful in helping to balance the tonal range among highlights and shadows. Detail is increased within shadow regions while a halation effect around highlights is created which can further enhance a scene's appearance or produce a desired effect.

This filter has a grade of 1/8. Grades of 1/4, 1/2, 1, 2, 3, 4, and 5 are also available where this filter type's effect becomes approximately twice as strong with each grade number increase.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. No front or rear threads are included on this filter's ring, or mount, which is 138mm in diameter and designed for use in third-party or custom filter holders.

Q: 1. Will this lens kit fit on my Nikon D7100? 67mm lens?

A: The Tiffen 138mm Close-up +1/2 Lens is designed to be used on lenses that have a 138mm filter thread size. If your lens has a 67mm filter thread size, the Tiffen 138mm Close-up +1/2 Lens will not fit onto your lens.

Q: 10. will this work with a canon 18-135mm lens?

A: It is the right size for your lens but if you use it at the widest angle you'll get some vignetting where the edge of the filter will appear as a dark shadow in the outer corners of the image. It won't be a problem at longer focal lengths. This is tolerable if you can crop these corners in post production. This filter will really raise the quality of light and colour in your landscapes.
