  • Ultra-thin 5.2 mm frame prevents vignetting on wide-angle lenses
  • Double-sided multi-coating maximises light transmission for clear images
  • Japanese optical glass delivers crystal-clear optical quality
  • Protects front lens element from dust and physical damage
  • Easy-clean surface simplifies maintenance for hassle-free use

Ultra-thin 43mm L395 UV filter

The NiSi 43mm L395 SMC UV Filter is a protective round filter designed for photographers who need to shield their lens front element from dust, scratches and moisture. Its ultra-thin 5.2 mm frame prevents vignetting on wide-angle lenses, making it suitable for landscape and architectural work. High-quality Japanese optical glass with double-sided multi-coating maintains light transmission and image clarity.

Replaces standard-thickness UV filters

Standard UV filters with thicker frames often cause dark corners on wide-angle lenses, especially at wider focal lengths. This filter upgrades that limitation by using a 5.2 mm frame that eliminates vignetting on super wide-angle optics. The improvement is worth it when shooting expansive scenes where edge-to-edge brightness and sharpness are critical.

Handles wide-angle protection without vignetting

The filter comfortably protects the front element on 43mm threads while preserving corner illumination on ultra-wide lenses. It runs out of utility on lenses with larger filter threads or when a circular polariser or neutral density effect is required instead of UV protection.

Questions about this item

Will the 5.2 mm frame thickness clear a 43 mm wide-angle lens without vignetting?

The ultra-thin 5.2 mm frame is designed to prevent vignetting on wide-angle lenses, so it clears the front element without dark corners.

How do I install the 43 mm filter and what step do people skip?

Screw the filter onto the 43 mm front thread until snug; the step often missed is cleaning the lens and filter glass first to avoid trapping dust.

What maintenance does the multi-coated Japanese optical glass need over time?

The double-sided multi-coating resists smudges; clean with a blower, then a microfibre cloth and lens fluid using a circular motion when marks appear.
