The Haida Multi-coating Circular Polarizing (PROII) filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

Haida MC C-POL (PROII) filters are constructed from high quality glass for increased optical clarity and color fidelity. They feature an aluminum filter ring for durability as well as jamming prevention. This filter is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters.

Athabasca NDX

NDX refers to adjustable ND, consisting of 2 pieces of opposed polarizer. When going through the first polarizer, light will go in through one certain direction; when light goes through the second polarizer, as the polarizing directions are different, light will be weakened. When the two polarizers are rotated in opposite directions, transmittance changes from high to low.

Main Functions:

NDX has infinite adjustment from ND2-ND400, with infinite light adjustment from 50%-0.25%.

Deficiency:

Due to the physical structure of NDX, opposed polarizers will cause the uneven light in the picture. Cross light would appear when density reaches 420 when NDX is applied to ordinary lens. So ND1000 is achieved theoretically but actually it can narrowly reach 400. Even the adjustment is limited to 400 on NDX, cross light is not completely avoided on all lens, since cross light appearance varies on different lens in different focal lengths.

A compact instant film camera, the smokey white instax mini from Fujifilm has been updated for selfie shooters and features a range of convenient controls for producing credit card sized prints. The sleek design incorporates a Fujinon 60mm f/12.7 lens, which offers a fixed focus from 2' to infinity, and a small selfie mirror is built into the front of the lens design for accurately composing self-portraits. Alternatively, a macro attachment lens is included to reduce the minimum focus distance for working with close-up subjects. For general shooting, the optical viewfinder is available and incorporates a central target spot to aid in composing images.

For controlling the look of imagery, the aperture setting can be changed in four steps, from f/12.7 to f/32, to suit various shooting conditions ranging from indoor lighting to bright sunlight. The dedicated hi key mode produces intentionally over exposed frames for a distinctly creative look. An automatic flash is built in to provide additional illumination when shooting in low light.
