Overview

The Tiffen 30.5mm Sky 1A filter serves a dual purpose: it acts as a physical barrier protecting your lens from everyday hazards like dust, moisture, fingerprints, and scratches, while also providing a slight optical correction. The Sky 1A designation means the filter carries a subtle pink tint that absorbs ultraviolet light and reduces the cool blue cast that often appears when shooting in open shade or under overcast skies. Built with Tiffen's ColorCore technology — where the filter material is laminated between two layers of optical glass — the 305SKY delivers consistent color rendition across the entire surface.

At 30.5mm, this filter fits a relatively niche thread size typically found on compact camcorders and select smaller lenses. For owners of these devices, the Sky 1A provides an easy and affordable way to keep the front element protected at all times without introducing noticeable color shifts or light loss. It threads on and stays on, making it a practical choice for users who want set-it-and-forget-it lens protection with a mild warming benefit for outdoor shooting.

Built with precision optical glass and ColorCore technology for dependable image quality, this Sky 1A filter is manufactured by laminating the filter material between two pieces of optical glass, ground flat to a tolerance of 1/10,000th of an inch and mounted in a precision metal ring.
