The Tiffen 6.6" Low Contrast Filter 1/2works to lessen contrast across the image by creating a small amount of controlled flare near highlight areas. This enables greater detail to be attained in shadow regions, while unaffecting the values of highlights, in order to produce lower apparent contrast. This filter is ideal for use during midday and other high contrast lighting situations when it is difficult to control both overexposed highlights and underexposed shadows. The 1/2 density provides less contrast adjustment than the 1 density, but more than the 1/4 density filter.

Tiffen filters are 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 10,000th of an inch. This filter measures 6.6 x 6.6" / 167.6 x 167.6mm.

Low Contrast for Greater Shadow Detail    Does Not Affect Highlight Values    Ideal for Midday and Bright Conditions    ColorCore Technology

Ideal for use during midday and other high contrast lighting situations when it is difficult to control both overexposed highlights and underexposed shadows.

Lower contrast results in greater shadow detail when properly exposed.

Q: 1. Can I stack these filters in front of each other? Or will that cause visual issues?

A: You can stack the Tiffen Full Spectrum IRND 0.6 filter, however you may potentially experience flare.

Q: 2. what wider focal length The Tiffen Digital HT CP is compatible?. It seems TIFFEN have a CP Wide angle but with inferior quality (no coating) than the HT CP. so is the HT CP compatible with 17-28mm focal length?

A: Yes this filter would be suitable for a 17-28mm focal length.

Q: 3. How many steps are recommended of IRND filters to build a set to work primarily in Sony sLog mode?

A: Please contact techsupport@tiffen.com for assistance as this question is more in depth than a response here can satisfy.

Q: 4. What Filter Thickness is? 2 or 4 mm?

A: Tiffen 4 x 5.65" Full Spectrum IRND 0.6 Filter is a 4mm glass filter.

Q: 5. 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.

Q: 6. Does this have female threads on the outside to attach a ND filter ?

Q: 7. Do the Tiffen IRND filters come with any pouch or case?

A: The Tiffen 4x4 Full Spectrum IRND 1.2 Filter comes with a pouch.

Q: 8. Do the Tiffen IRND filters come with any pouch or case?

A: Comes with a case.

Q: 9. Does this filter come with a pouch?

A: Yes, it comes with a filter pouch.

Q: 10. How does this compare to the Tiffen Digital HT CPL that is about $40 more? Which one is higher quality for videography/filmmaking?

A: While both the Tiffen Digital HT (High Transmission) Circular Polarizing Multi-Coated Filter and the Tiffen Circular Polarizing Wide Angle (Low Profile Design) Filter are polarizing filters and would have similar usage, the Tiffen Digital HT (High Transmission) Circular Polarizing Multi-Coated Filter has a titanium anti-reflective transmission coating that makes the filter extra hard and durable, making it easier to clean, and offers better light transmission with less reflections on the coatings they use. The Digital HT filter would be the better quality option between the two filters, but both may be used to polarize light and reduce reflections on non-metallic items while assisting in increasing contrast/saturation and deepening the blue color in the sky (depending on your orientation in relation to the sun).
