3.5mm ELIMINATES VIGNETTING

The X1 UV Filter features a 3.5mm ultra-slim double-threaded frame profile to eliminate vignetting on wide-angle full-frame setups.

Why 3.5mm? In our lab tests 4.2mm was the frame width at which point 1-stop of light falloff (vignetting) became visible on images with 16mm wide-angle setups on full-frame cameras.

LASER ENGRAVED

We also laser engrave each X1 UV Filter with a unique serial number. When you activate your 25 Year Ironclad online we associate your X1 serial number to you, so any future discussions regarding your X1 UV are tracked, issues recorded, all of which goes directly into our design and prototyping pipeline.

WEATHER-SEALED DURABILITY

Every filter we make, including the X1 UV, is weather-sealed. If you want to ensure that your lens maintains out-of-box optical performance for as long as possible, Canon, Nikon and Sony recommend protective filters for the purpose of completing a lens weather-seal. “Without a filter, the lens is not dust or water resistant.”, as Canon states on page 2 of their lens user manuals.

25 YEAR SUPPORT

We stand behind each filter with our 25 Year Support and US-based phone, email and live chat.

WEATHER-SEALED

Our X1UV filters are designed to hold up for years of regular use in the field. Each filter completes the weather-sealing of the lens and can withstand extreme wind, salt water, dust and other abrasive elements and conditions.

NANO-COATING

Each filter incorporates our state-of-the-art Nano Coating technology which repels dirt, water and other debris by beading up on the surface rather than absorbing and smearing.
