  • Helps to Eliminate Reflections and Glare
  • Reduces Haze and Blue Cast in Landscapes
  • Greater Color and Tonal Saturation
  • Single-Layer Coating
  • Optical Glass Construction

The Sigma 105mm DG Single-Layer Coated Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions.

A circular polarizer 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.

This filter features a single-layer coating to help reduce surface reflection and ghosting while helping to increase overall clarity and contrast.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° from the sun.
Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
Single-layer coating provides a reduction in surface reflections and helps to reduce flare and ghosting.

        By John

        from Williamsburg, Va.

        Comments about Sigma 105mm DG Single-Layer Coated Circular Polarizer Filter:

        I bought this to mount on my Lee filter system and found the I had severe vignetting at 24mm. I had wanted to go even wider but this filter will be left in my bag unless smeone can help.

            Appears to be a high quality product that makes it hard to justify the much-more expensive alternatives.

              I shoot a lot on the water and in bright light, so I went with a Sigma filter for a Sigma lens. The Sigma products seem to be very compatible with each other, at least in my experience.

                On Sigma 120-300 2.8. Fits on nicely. Nice, but bulky, case to protect it when not in use.

                    This is a good filter. Made in Japan, metal surround, heavy and well made. Comes with a black, hard leather case (red velvet on the inside).

                    Does not seem to noticeably degrade image quality whatsoever. Certainly not cheap though, so it had better perform well, eh? I use it with an 82mm->105mm step up ring on my Sigma 10-20mm f/3.5. No vignetting even at 10mm!

                      The description and subsequent research revealed this polarized lens is amongst the top performing filters in its class. It compliments my lenses well with no vignetting and hinderance to overall performance. A must have if you desire to photograph scenes just as you see them...if not better!

                      Comments about Sigma 105mm DG Single-Layer Coated Circular Polarizer Filter:

                      A very good Polarizing filter for Digital Photography.
                      All Polarizing filters have moving parts, having a bit thicker rings. Therefore in most cases one needs much bigger filter than the actual thread on the wide angle lens, to avoid vignetting.
                      105mm with a low profile 82-105mm adapter works very well, covering very well the whole frame when used with 16mm wide angle lens.
                      A must for Canon 16-35mm zoom.
