SIGMA 72mm UV camera filter

What this filter is and who it's for

The Sigma 72mm Multi-Coated DG UV Filter is a clear optical filter that absorbs ultraviolet light to reduce the bluish cast often found in daylight photography. It adds no colour shift or contrast change, so it can be stacked with other creative filters. The super multi-layer coating cuts flare and ghosting for clearer images. It also serves as a permanent shield against dust, moisture and accidental scratches on the front lens element.

Who this suits and who should look elsewhere

Photographers who want a single filter to leave on a 72mm thread lens for everyday protection and UV correction will find this a practical choice. It suits shooters who stack filters because it introduces no tint of its own. Buyers needing a polarising effect, neutral density reduction or a coloured warming filter should look at dedicated filter types instead. Those with lenses that take a different thread diameter cannot use this filter without a step-up or step-down adapter ring.

Capacity and headroom

The 72mm thread fits directly onto any lens barrel marked with that diameter, providing full coverage without vignetting on compatible optics. The multi-coating maintains high light transmission and contrast across the frame under normal shooting conditions. The filter will not reduce exposure or alter white balance, so it imposes no creative limitation. It cannot block strong reflected glare from water or glass, nor can it extend exposure times for motion blur effects.
