The SQ100 Filter Holder Kit from Hoya is a square filter holder system that gives photographers the means and freedom to fully express creativity and realize artistic goals. The system features a sophisticated filter holder kit and a line of high-quality filters, making it an exceptional tool for advanced and professional photographers shooting landscapes, cityscapes, and more. As square filters are usually larger than the front glass element of the lens, the chance for vignetting is reduced to a minimum, even when stacking filters. Stacking filters is more effective with a square filter system as it can carry up to three square filters in addition to the polarizer. Switching filters is faster and easier than with conventional round filters. In addition, filter holders can be rotated, giving the photographer the option to reposition the line of graduated ND filters.

Separately available adapter rings allow the system to be used with a wide range of lenses with a range of thread sizes, so it is not necessary to buy the same filter multiple times for different lenses. The Sq100 holder kit includes a 100mm-wide square filter holder, a polarizer, and two geared adapters that fix the polarizer inside the holder and attach it to the lens. The body of the filter holder is made of aluminum for optimal durability while being still lightweight. It features a gapless design plus a black gasket on the edge of the inside holder ring to minimize light leaks.

The circular polarizer can be rotated inside the frame for perfect reflection and saturation control. With its large diameter of 86mm, the polarizer filter won't cause any vignetting with most lenses. HOYA's special water-repellent multi-coating is applied to the polarizer's optical glass, making cleaning easy and stress-free. The polarizer adopts a high-transparency polarizing film for fast shutter speeds. This translates to no less than nearly 1/2 stop more light entering the lens while yielding the same polarization effect, when compared to other polarizing filters.

Related Questions and Answers

Q: 1. Is it normal for a circular polarizer to have movement once attached to the lens?

A: Define movement. It screws on and that should be tight (no movement). The filter itself turns to orient the angle of the polarization (as opposed to a non circular polarizing filter which only really works when shooting in landscape mode)

Q: 2. Hello,I noticed the only difference between this Hoya circular polarizer and last years model is this one is not coated. What is the benefit of a non-coated filter?Sincerely,Daniel

A: The main benefit of a non-coated filter is a lower price point. A multi-coated filter will provide dramatically improved light transmission and resistance to glare. If you have the option to spend more for multi-coating, I would definitely recommend it.

Q: 3. What country are Hoya filters made in?

A: The Hoya 67mm NXT Circular Polarizer Filter is manufactured in the Philippines.

Q: 4. Is this the same filter as the Hoya NXT Circular Polarizer filter, just updated?

A: According to Hoya, the NXTPlus filters are improved over the NXT-series because they "use better glass, an improved multi-coating process, more multi-coated layers for better light transmission, AND add a new 'Waterproof' Top-coat to repel water quickly away from the surface which makes it easier to clean and more fun to use."

Q: 7. how many f stops of light transmission are reduced?

A: It has a filter factor of 2 to 4 (1 stop minimum, 2 stop maximum).

Q: 8. does this fit Olympus tough TG5 ?

A: Yes, it does. But you have to buy the Olympus CLA-T01 adaptor in order mount the filter. This is the same adaptor that is used to mount the Olympus wide-angle and telephoto extender lenses on the camera.

Q: 9. Does this filter rotate?

A: Yes, the circular polarizer rotates. it enable you to add contrast to colors outdoors, and remove the majority of unwanted reflections form non-metallic surfaces such as water or windows. Keep in mind that if you have a powerful light source 9such as the sun) in the frame, it will eliminate any polarization effects.
