I received this filter in good condition and on time. quality seems good. This was my first experience with a neutral density filter, which I used during the August 21, 2017 solar eclipse. I mainly used it as extra protection as I also used a cheap sun filter. I look forward to experimenting with this as it offers a variation in light. To do anything with direct sunlight you need a stronger ND filter than this. It worked well during totality (2min 36sec) even though we had clouds so I was able to experiment a little with the variable filter without the sun filter. However, I have attempted to give this only limited time to experience the greater effects of totality.

I have ordered three of these variable ND filters for my Canon lenses and have found these filters to be of excellent quality. The filters work in the same way as a polarizing filter. The outer edge of each filter is knurled for easy gripping and adjustment. The outer lens is slightly larger than the inner lens, allowing for wide-angle lens vision.
