7artisans 58mm ULR Ultra-Low Reflection MRC UV Filter

SKU CH-XJC4-MNX6G

A 58 mm UV filter with B270 optical glass, 99.6% light transmittance and 0.1% reflectivity in a 3.8 mm frame

  • B270 optical glass delivers superior clarity and durability
  • 6% light transmittance produces bright, crisp images
  • 1% reflectivity minimizes glare for vibrant, accurate photos
  • 8 mm thin frame prevents vignetting on wide-angle lenses
  • 8H-hardness nano coating resists scratches, water, oil and mildew

Purpose and Fit

The 7artisans 58mm ULR Ultra-Low Reflection MRC UV Filter fits 58mm threads and serves photographers who want lens protection without degrading image quality. It uses B270 optical glass with a multilayer nano coating to maintain clarity for 4K and 8K video work. Buyers who need a different thread size or a circular polariser should look elsewhere.

Sustained Behaviour

The coating stack keeps reflectivity at .1% and light transmittance at 99.6% even after repeated cleaning, so contrast stays consistent during long shooting sessions. Hardness exceeds 8H, resisting scratches from dust and frequent wiping. The 3.8mm thin frame prevents vignetting on wide-angle lenses throughout extended use.

Interface Limits

The filter mounts via standard 58mm front threads, adding only 3.8mm of depth to the optical path. Double-sided waterproof and oil-proof layers shed moisture and fingerprints, but the glass itself has no electronic contacts or data interface. It cannot communicate with the camera or alter exposure metadata.

Questions about this item

How much light does the 99.6% transmittance filter actually let through during all-day shooting?

The filter transmits over 99.6% of incoming light, so exposure stays virtually unchanged even during extended sessions.

What thread size must my lens already have for this 58mm filter to mount directly?

Your lens needs a 58 mm front filter thread; the filter screws straight onto that thread with no step-up ring required.

Will the 3.8mm thin frame vignette on my older wide-angle zoom at its widest setting?

The 3.8 mm frame is designed to avoid vignetting on wide-angle lenses, so older zooms should stay corner-to-corner clean at their widest focal lengths.
