I ordered three of these variable ND filters for my Canon lenses and have found these filters to be of excellent quality. The filters operate in the same way a polarizing filter does. The outer rim of each filter is knurled for easy grip and adjustment. The outer lens is slightly larger than the inner lens which accomodates the view of wide angle lenses.

Great product! The variable density is perfect for making quick changes on the fly to get the perfect shot.

Works well nice color .i actually dont see any diffencies in color toning as hear you can a greenish tone or yellowish. But for me its just fine.

Used for my 85 1.2. It does a bit of what i need it to do, but SEVERELY degrades image quality. I would rather wait for more ideal lighting situations and shoot that use the images coming though this filter. Perhaps it's more of a personal preference.

I purchased this variable ND filter to use on Nikon D300s with 18-200mm lens. I tested the filter against a white wall over various settings: f-stops, shutter speeds, ISO and ND settings. Works quite well at all settings except extreme ND where I saw uneven brightness areas on the exposure but I had to push ISO past 3200 to even get the exposure. At 3200 ISO it could also be the camera. In all I am very satisfied and would recommend this variable ND filter for most amateur photographers. For amateur photographers the price is right.
