This filter specially added accurate stop numbers and magnetic attraction designs, which are rather easy when taking pictures because the filter can be changed just in one second! Moreover, this interchangeable variable ND filter is also highly recommended because of the performance and practicality. The 2-5 stops are perfect for taking videos and the 6-9 stops are dedicated to photography. It can be interchanged pretty fast, while the price is lower than 2 variable ND filters! 

What you concern mostly is the vignetting of the filter, the picture below demonstrates there is no vignetting when using and low color cast. Meanwhile, the waterproof nano-coating surface enables you to use underwater! By the way, the weight of the Interchangeable Magnetic Variable ND Filter is almost 9g lighter than the previous VND filter.
