I was pretty late to jump onto the ND filter bandwagon because I am old photographer and still to this day shoot film 90% of the time. With film, we learned how to make camera adjustments to do the same thing you would achieve with these filters. well, nearly the same thing.... I am shocked at how much simpler it is to work in harsh light, and to capture long timed exposures with using this Variable ND filter!

One question I had was "will this work with film or pretty much just for digital?" and I am happy to say that it does come in handy for film as well, but I do believe that its greatest strength is in digital photography.
This filter is one of the best quality built filters I have ever come across, its silky smooth to rotate, but has enough friction that it stays right where you set it at and does not slip to another adjustment. I could not believe my eyes, but it also acts as a mild Polarizer filter too. I was able to shoot in very harsh and bright sunlight and using the darkest setting have a exposure that was nearly 2 minutes long and was able to see right through the reflection of the water. I have never been able to do that before!

I really love the little orange nubbin that they call a "putter" on this filter too. it just makes adjusting it so much easier. I am totally sold on the use of ND filters now, and with this one being variable adjusting it is the only one i will ever need! very happy with it!
