This Platinum PT-MC400VND67 variable neutral density filter is compatible with most 67mm, 58mm and 52mm lenses, with included adapters, and lets you reduce incoming light to allow wide apertures in bright light and other creative shooting options.
I have more than a few filters lying around including a handful of ND filters. I have only had this filter for a few days now and WOW... I love it. I get the same results with this as I do stacking my other filters. And for doing landscapes, which I love, I often find myself spending too much time wasting on setting up and changing out filters. With this I just turn the filter one way to increase the darkness and the other to lighten it up. Skies are bluer Grass is greener, and best of all those at longer exposures those clouds are super smooth. From what I can tell the build quality is very good/sturdy. Time will tell but as of now, an AMAZING product... Wish I would have gone to Variable long ago!
Going to the Anna Maria Island Beach Saturday and I'm very happy to have this in my arsenal!!!
