LEE Elements Big Stopper Circular Filter - 77mm

It means the filter reduces the light reaching your camera's sensor by 10 full f-stops. This is equivalent to darkening the scene by a factor of 1024 times, allowing for significantly longer exposure times.

Yes, it can be used for video to achieve motion blur effects, such as smoothing out choppy water or creating a cinematic look for fast-moving scenes, provided you can adjust your shutter speed accordingly (typically double your frame rate).

While the screw-in design is generally slim, some vignetting might occur on extremely wide-angle lenses (wider than 24mm on full-frame). This is more common with stacked filters. For standard wide-angle lenses, it's usually minimal.

Use the provided microfiber cloth for light dust. For smudges, a lens cleaning solution on a damp cloth can be used. Always wipe gently from the center outwards.

LEE Filters are known for minimizing color cast. While extreme ND filters can sometimes introduce a slight cast, the multi-layer optical coatings on the Big Stopper are designed to reduce this. Any minor cast can typically be corrected in post-processing.

Yes, you can stack it with other filters, but be aware that stacking filters, especially on wide-angle lenses, can increase the risk of vignetting and reduce overall image quality due to increased light obstruction.

Ensure you are using the correct filter size (77mm) for your lens. Check for any debris on the lens threads or filter threads. Try to screw it on gently and straight, without cross-threading.

This can sometimes occur with very strong ND filters. Adjust the white balance in your camera or in post-processing software to correct the color cast. Ensure the filter is clean.

Autofocus systems can struggle in very low light conditions created by the filter. It is recommended to focus your lens *before* attaching the Big Stopper filter. Switch to manual focus afterwards.

Recalculate your exposure compensation. A 10-stop filter requires multiplying your base shutter speed by 1024 (2^10). For example, if your meter reads 1/125s, your new exposure should be approximately 1 second (1/125 * 1024 = 8.192s, which rounds to 8s for practical purposes).
