The Tiffen 3 x 3" 1 Straw Soft-Edge Graduated Filter helps to specifically add a warm, golden yellow coloration to skies and other bright areas of an image while allowing a portion of the image to remain neutrally colored. The filter's coloring is densest at the edge and tapers to clear by the middle, with a soft-edged transition between the density and clear areas. The 1 color density provides less straw coloration than the 2 density filter.

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. It measures 3 x 3" / 76.2 x 76.2mm.

1 Density Color Graduated Filter    Straw Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a golden yellow coloring to select areas of the image.

Graduated filter design keeps a portion of the image neutral, resulting in a more realistic look while allowing for the sky or other bright areas to take on the color of the density.

Q: 1. Do CP.3's allow for a protective filter to be screwed on?

A: No, for any filters you will have to use a matte box.

Q: 2. If using a super 35mm sensor with this full frame lens, would one need to use the crop factor of 1.5 to determine the equivalent field of view?

A: Yes you would. To take it a step further all lenses are listed by their physical focal length and from there the crop factor needs to be taken in to account. Even lenses that only cover a Super 35mm sensor will be subject to a crop factor. Any lens, regardless of it is covers Super 35mm or Full Frame, will need to have the 1.5x crop factor added.

Q: 7. How does this perform in terms of CA levels and purple fringing at all aperture settings?

A: It is our understanding that the optical properties of the CP.2 and CP.3 lenses are very similar. There were reports of some CA with the CP.2 lenses. Being that these are Zeiss, we doubt that this really is something that the cinematographer will be concerned about let alone his audience. CA is dependent on lighting, focus and aperture as well. We would encourage you to rent and test before you buy to make sure these lenses are for you.
