Graduated Neutral density filter

The filter holder allows the user to adjust the location of the dark half of the filter. There are circular graduated filters, but your horizon will always have to be in the center of the frame, having the adjustable filter holder is a huge convenience. The filter was $30, and the holder kit was $20. The same filter holder can be used with all different thread sizes, you only need to buy the mounting ring specific for each filter thread size. Saves you the cost of buying muliple filters. The filter holder pops on and off, this is much easier than having to thread filters on.

The filter holder is on the verge of vingetting when using my Sigma 20mm with an 82mm thread. This is for a Canon 1dmk2 with a 1.3x crop. I assume the filter holder will vingette on a full frame camera. Originally the filter holder held 3 filters, I cut the last two slots off so my filter is now only holds one filter. This should eliminate my problem with vingetting.
