The Sigma 72mm WR UV Filter is a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. This filter is especially useful when photographing at high altitudes or around bodies of water. No additional coloration or contrast is provided, allowing you to pair this filter with others.

A UV filter is also useful as a general protective filter to leave on a lens at all times. This filter helps to reduce dust and moisture from reaching your front lens element and provides additional protection in case of drops or situations where scratching could occur.

This Sigma WR UV Filter is coated to repel water drops and resist smudging from fingerprints. It is also treated to exhibit antistatic properties to prevent microscopic dust from clinging to the front surface. This helps to ensure sharp images.

Q: 1. Can I use this with all canon cameras?

A: You can use this with all cameras on the planet, provided the lens accepts 55mm filters. the filter's diameter (55mm) must match that of the lens (filter diameter is mentioned in the front of the lens).

Q: 2. Does ir cut only serve to reduce red from sunlight or is this also necessary in artifificial light like LED?

A: LED white lights typically remove unused spectrums to save on power so the difference under artificial light should be minimal. The largest gains will be under sunlight and UV/IR specific lighting. Unless the camera is full spectrum modified you will likely see very little difference under any light but almost none under modern artificial lighting. I would not buy an IR cut filter unless the camera is full spectrum modified as your camera already has one built in and UV filters are much less expensive. HTH.

Q: 9. Hu guys, I'm after a UV filter for a Canon 16-35 f2.8 II. I think I've narrowed down my choices to: (a) Hoya 82mm Ultraviolet UV Haze HD (High Density) Digital FilterB&H # HOUVH82 ? Mfr # XHD82UV(b) Hoya 82mm HD2 UV Filter B&H # HOUVH282 ? Mfr # XHD2-82UVI'm just wondering what the main difference are between the two.Is it just a case of the HD2 being thinner? Is the Haze on the first one a reference to a colour/effect? Thanks for your help.
