Tiffen 6.6x6.6" Low Light Ultra Contrast 1 Filters - Bright lights or sunlight create problems when the ratio between the highlight and shadow areas is beyond the latitude of the film.

If you expose for the highlights, the shadows appear without detail. If you expose for the shadows, the result is washed-out, overly bright highlights. Contrast reduction is achieved by lightening shadows without overexposing highlights or by darkening highlights without darkening shadows further.

Tiffen Low Light Contrast filters are more effective in dealing with contrast in lower light scenarios

Tiffen Ultra Contrast filters work by using the ambient light surrounding the image area as well as the light in the actual image area itself

They lower contrast uniformly, with little or no loss of sharpness, throughout the scene even when there are varying degrees of brightness within the image

Shadow areas are opened up, revealing more detail, but without any flare or halation from direct light sources or bright reflections

Even direct shooting into the sun produces no flare or halation

Q: 5. Was this made for film or digital? Do you have to angle it slightly for digital?

A: The Tiffen 4 x 5.65" Ultra Pol Linear Polarizer Filter, being a linear polarizer, is not good for digital photography. For digital photography, you would want to use a circular polarizing filter. Here is a link to the circular polarizing filter options in the 4 x 5.65" size: https://bhpho.to/4dOpbz9.

Q: 8. Will this work with the sony 10-18mm lens?

A: The totally correct answer is I don't really know. On the other hand I see no reason why it should not work. I bought this filter in the 67mm size for my Canon EF-s 10-18mm lens for a camera with an APC size sensor. The Canon lens is equivalent to a16-28.8mm full frame lens while your Sony lens works out like a 15-27mm equivalent. I bought the low profile filter when I realized that my regular polarizer vignetted at 10mm. The new filter solved this problem. Even though your lens is a scant millimeter (equivalent) wider and the size is 5mm smaller I still believe that the filter will work for you without vignetting, which I assume is your concern. Looking at the geometry of the two lenses I think you will be safe.
