Sigma launches redesigned lens filter lineup
Posted on Sep 8, 2026 by Pro Moviemaker
Sigma have announced the renewal of Sigma’s filter series for interchangeable lenses. The entire lineup has been completely redesigned to achieve further performance improvements. Additionally, the design and packaging have been updated to align with Sigma’s new visual identity, introduced in 2025.
Four filter models will be released on November 5th, 2026: the Sigma WR Ceramic Protector PTC-21, a ceramic protector offering exceptional impact resistance; the Sigma WR Protector + UV PUV-21, featuring UV protection and water- and oil-repellent coating; the standard Sigma Protector LPT-21; and the Sigma WR Circular PL Filter CPL-21, a circular polarising filter with water- and oil-repellent coating.
Key Features
Completely redesigned construction
As part of this renewal, the entire lineup has been redesigned from the ground up to further minimise impact on image quality while enhancing overall usability. Improvements to the surface treatment of the filter frames reduce internal reflections compared to previous models, while an optimised design has enabled a slimmer profile for the large-diameter 95mm and 105mm sizes.
New exterior design and packaging
These filters feature an exterior design and packaging aligned with Sigma’s new visual identity, introduced in 2025.
Verified compatibility with all Sigma lenses
Compatibility with all Sigma lenses has been fully verified, allowing for worry-free shooting without vignetting, even when using ultra-wide-angle lenses. Despite the slim design, these filters ensure secure lens cap attachment, providing users with peace of mind.
