Thin 52mm variable ND filter with dark tinted glass and silver magnalium frame

Urth

Urth 52mm ND2-32 Variable ND Filter Plus+

SKU CH-YWAP-MA2W4

A 52 mm variable neutral-density filter that cuts 1 to 5 stops using 20-layer nano-coated German SCHOTT glass in an ultra-slim magnalium frame with a locking rim to prevent over-rotation

  • Blocks 1-5 f-stops for shallow depth and motion blur
  • Locking rim prevents over-rotation and X-effect
  • 20-layer nano-coated German SCHOTT glass for high transmission
  • Ultra-slim 52mm frame avoids vignetting on wide lenses
  • Tough magnalium construction backed for lifetime use

Variable ND2-32 Filter for 52mm Threads

The Urth 52mm ND2-32 Variable ND Filter Plus+ mounts on lenses with a 52mm front thread. It provides a continuous 1 to 5 stop reduction for photographers and videographers who need flexible exposure control in changing light conditions. The ultra-slim magnalium frame prevents vignetting on wide-angle glass. A built-in locking rim stops over-rotation and eliminates the X-effect at maximum density.

Consistent Transmission Under Changing Light

Twenty layers of nano-coating on German SCHOTT glass deliver a uniform transmission curve across the entire 1-5 stop range. The coating resists water, oil and scratches, so the glass stays clean during extended outdoor sessions. Light transmission remains predictable as you rotate the filter, avoiding sudden density shifts that would ruin a long exposure or video take. The hard-wearing magnalium construction maintains alignment through repeated adjustment.

Upgrade Path from Fixed ND or Uncoated Variables

This filter replaces a set of fixed neutral density filters when you want to travel light and adapt quickly. It also supersedes uncoated variable ND filters that suffer from colour cast, uneven darkening or sticky rotation. The jump is worth it for shooters who work in variable daylight and need reliable stop-for-stop accuracy without carrying multiple filters. It is not for users who require densities beyond 5 stops or who shoot with lenses lacking a 52mm thread.

Questions about this item

How much heat does the 20-layer nano-coating generate during all-day video recording?

The passive glass filter produces no heat of its own; it only reduces light entering the lens, so the camera sensor runs at its normal temperature.

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

Your lens needs a 52 mm front filter thread; otherwise a step-up or step-down ring is required.

Will the ultra-slim rim prevent vignetting when stacked on my older circular polariser?

The ultra-slim rim is designed to minimise vignetting, but stacking any filter increases the risk on wide-angle lenses; test at your widest focal length.
