Essential protection for 72mm Sigma lenses

This front lens cap fits a 72mm filter thread and shields the front element from dust, smudges and impacts. It is compatible with a wide range of Sigma lenses used for landscape, architectural, event, portrait and macro photography. The cap delivers a secure fit for daily protection of your optics.

Snap-on design for quick daily use

The cap uses a standard centre-pinch mechanism that allows one-handed removal and replacement even with a lens hood attached. Its construction is praised for a precise, tight fit that stays in place inside a bag. No tools or adapters are required for mounting.

Verify the 72mm thread before ordering

Check the front of your lens barrel or the existing cap for the 72mm symbol to confirm compatibility. This cap will not fit lenses with a different filter-thread diameter. Buyers who need a cap for another thread size should look for the matching diameter.

Questions about this item

Does the 72 mm thread match the filter thread on my Sigma 30mm F1.4 ART DC HSM?

Yes, the cap uses a standard 72 mm thread that matches the filter thread on the Sigma 30mm F1.4 ART DC HSM and other listed Sigma lenses.

Will this cap fit over the hood petals on my Sigma 10-20mm F3.5 EX DC HSM?

The cap threads directly onto the 72 mm filter threads at the front of the lens, not over the hood, so remove the hood before fitting the cap.

How do I attach the cap without cross-threading the 72 mm threads?

Align the cap squarely, turn it counter-clockwise until you feel the threads engage, then turn clockwise to tighten gently.
