・Without changing the aperture, the Variable NDX filter allows the freedom to change the shutter speed according to the effect desired. For example, without adjusting the aperture, the same 1/60 scene can be taken using the Variable NDX filter with shutter speeds from 1/20 to 6 seconds, with just a turn of the outer filter ring. The problem of diffraction is eliminated by being able to work with a slow shutter speed. ・With the Variable NDX filter, the shutter speed remains constant for a wide aperture easily creating a blurred background effect. ・Even with a shutter speed of 1/8000 seconds, a large aperture of F1.4 or F1.2 can cause overexposure / highlight clipping. With the Variable NDX filter, this overexposure is eliminated. ・For HD video-enabled cameras, use the Variable NDX filter to easily adjust light control and shutter speed. The Variable NDX filter makes it simple to produce blurred background effects, simulate a night scene or create manual fade in / fade out effects. It is also perfect for use in bright locations such as beach or snow scenes and city scapes. ・The singular versatility of the Variable NDX filter not only replaces a whole set of stacking neutral density filters it also removes vignetting which may be caused by using multiple filters. //Attention: ・Filter Size(mm): 77-82 Please use the step-up ring if you want to use other size lenses. ・When using a neutral density higher than 450, cross-like color variations may occur. Structurally this problem cannot be eliminated due to the 2 layers of polarizing film.This is a property of the filter and all variable ND filters. ・Display of the frame is only a guide. It can cause a slight error in the filter effect at the Maximum/minimum points.
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
