LEE Elements Big Stopper Circular Filter - 72mm

Its primary function is to block 10 stops of light, allowing for significantly longer exposure times in bright conditions. This is used to create motion blur effects in water, clouds, and other moving elements.

You need to add 10 stops to your camera's meter reading. For example, if your camera meters a scene at 1/60s, with the Big Stopper, you would set your shutter speed to approximately 1 minute (1/60s + 10 stops = ~60s).

While technically possible, it's generally not recommended for standard video recording unless you are specifically aiming for extreme slow-motion effects or time-lapses where long exposures are desired. Most video requires faster shutter speeds to maintain normal motion.

When used correctly and kept clean, the high-quality optics and coatings aim to minimize any impact on sharpness. However, extremely long exposures can sometimes introduce minute sharpness variations, and focusing accuracy is critical.

It is available in 67mm, 72mm, 77mm, and 82mm thread sizes.

Use the provided microfiber cleaning cloth to wipe away dust and fingerprints. For tougher smudges, use a lens cleaning solution applied to the cloth, not directly to the filter.

Information regarding warranty is typically found with the retailer or manufacturer's official documentation. Please refer to your purchase details for specific warranty information.

Attempt to focus on your subject *before* screwing on the Big Stopper. If using autofocus, ensure your camera can lock focus in low light or manual focus mode after attaching the filter. Some users may find it easier to focus using live view.

The Big Stopper can sometimes introduce a slight color cast. This is often a magenta or green hue. Modern editing software has tools to correct this in post-processing. Alternatively, some photographers experiment with custom white balance settings or pre-shoot color correction.

Ensure you are using the correct filter size for your lens. If it feels tight, do not force it. Check for any debris on the lens threads or filter threads. Gently twist back and forth to loosen if it feels stuck.

Accurately calculate exposure by adding 10 stops to your base exposure reading. For example, if your meter reads 1/125 sec at f/8, with the Big Stopper, your new shutter speed will be approximately 8 seconds (1/125 + 10 stops = ~8s). Manual mode or shutter priority is recommended for precise control.
