Sigma 86MM DG Filter (Digitally Optimised (DG) Filters)
Sigma 86mm has multi layer coating for treatment of highly_reflective_characteristic of image_sensors. Contrary to it, the mechanism used on other filters is such that light w'd reflect off the image_sensor and bounce back to the image sensor creating ghost effect. With the application of multi layer coating, the ghost effect is reduced to a greater extent. Sigma 86mm DG filter has the ability to deliver refine and balanced colour with greater accuracy.

Product Description

Digitally Optimised (DG) Filters
Sigma??s EX DG filters benefit from our 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.

Multi-coated UV Filter
This filter perfectly eliminates the harmful effect of ultraviolet light. The multi-coated UV filter can be used with both colour and black-and-white film and digital sensors. This is the most suitable filter for protective use and general photography.
