The Sigma AFF-940 72 mm UV Filter offers excellent protection for your sensor against harmful ultra-violet radiation, as well as providing physical shielding for the lens glass.
Digitally optimised UV filter
Treated with Sigma's dynamic multi-layer lens coating, this high-grade filter has been crafted with digital optimisation to offset the highly reflective nature of imaging sensors.
Older filters would reflect light off the sensor, bouncing it off the lens and filter elements to send it back into the image sensor. This would in turn cause abhorrent ghosting in images. With this great new multi-layer coating, this effect is thankfully and dramatically reduced.
UV'll be sorry
The Sigma AFF94-0 72 mm UV Filter goes to work to perfectly abolish the harmful effects that ultra-violet light can have on your camera and photographs. Multi-coated for decisive, thorough performance, it can be sued with both colour and black-and-white film and digital sensors, making it pleasingly versatile.
In living colour
Dramatically reducing image haze without upsetting colour balance, the Sigma A-FF940 72 mm UV Filter helps you achieve all-round better-looking photographs. Additionally, an optimum, beautifully neutral colour balance is ensured, also helping to increase the white balance accuracy of your digital camera.
On top of this light protection and colour enhancement, the filter physically protects the front lens element from dust and damage, so it's doubly practical.
A highly suitable filter for protective use and general photography, the Sigma AFF-940 72 mm UV Filter will be a valuable addition to your imaging kit bag.
