Big Stopper 10-stop ND filter
The Lee Filters LEE85 Big Stopper is a neutral density filter that reduces light entering the lens by ten stops. It is designed for photographers who want to create long-exposure effects during daylight hours. The 85x90mm glass filter fits compatible filter holder systems for creative landscape and urban photography.
Neutral density glass construction
The filter uses optical glass to achieve a consistent 10-stop reduction with a 3.0 density rating. It maintains colour neutrality across the frame without introducing noticeable colour casts. The solid glass construction provides durability for regular outdoor use in varying weather conditions.
Extended exposure creative control
Under sustained bright light the Big Stopper enables exposure times of several seconds or minutes rather than fractions of a second. Moving elements such as clouds, water or traffic render as smooth, blurred streaks while static architecture remains sharp. The fixed 10-stop density suits scenes where a single, strong reduction is required.

Questions about this item
How do I fit the 85x90mm glass into the Lee holder without vignetting?
Slide the filter into the front slot of the Lee 85mm holder with the foam gasket facing the lens; keep the holder rings tight so the 90mm height sits flush and prevents light leaks at the corners.
Will the optical glass need recoating or replacement after heavy field use?
The neutral-density coating is bonded to the glass substrate; clean only with a microfibre cloth and lens fluid — no recoating service exists, so replace the filter if scratches or coating wear appear.
At what point does the 10-stop density cause colour shift during very long exposures?
The 3.0 density extends exposures by roughly ten stops; beyond several minutes the filter’s inherent warm cast becomes noticeable, so set a custom white balance or correct in post.
