Four-Inch Diameter Drop-In UV Filter

[Guest Glenn Brady]

I've acquired a Century 3.5mm f/1.8 Extreme Wide Angle lens equipped with a filter holder that accepts filters four inches in diameter. Typically, these lenses were supplied with a filter holder accepting readily available 4½-inch diameter filters and I've found no four-inch diameter filters (which are larger than the largest series filter of which I'm aware). Does anyone know where I might get a four-inch diameter UV filter?

Try your local glass supply or framing company and ask them to cut you a piece of museum glass in the size you need.

Thanks. That sounds like a comparatively inexpensive solution.
