About Sigma 105mm EX DG

Digitally Optimised (DG) Filters
EX DG filters benefit from Sigma's multi-layer lens coating, developed to counteract the highly reflective characteristic of image sensors. With older style filters, light would reflect off the image sensor, bounce off the lens and filter elements and re-enter the image sensor, creating a ghost image. The multi-layer coating dramatically reduces this effect. In addition to this, an optimum, neutral colour balance is ensured, increasing the white balance accuracy of the digital camera.

Circular Polarizing Filter
This type of Polarizing filter has a large diameter and it also deepens the intensity of blue skies, eliminates glare. It not only reduces the reflection from non-metallic surfaces, but also increases colour saturation perfectly

Superior Value


from Shizuoka City, JAPAN  -  Semi-pro Photographer

Product used exclusively for nature photography with 8 x 10 camera & 300 mm lens. Cannot comment about consistency of effect because I have not used the product long enough for such a judgment; however, I see no reason why it would not maintain the same quality of results I have seen so far.

Questions about this item:

Shopper  Why Did You Choose This?
PEDRO B  I bought the Sigma 120-300 2.8 and decided that I needed the polarizer for it. Works as intended, but you need a suitcase to carry the lens and polarizer!
Shopper  threaded both sides?? Thanks! ;)
PEDRO B  Yes! It is threaded on both sides.
Shopper  Is this filter suitable for use on a non-digital lens? The lens I want to use it on is a Mamiya 75mm lens. Thanks
TONY S  Yes. I use it on my large format camera. Determining exposeure with it, however, can be tricky.
