A company called Style My Heart (my wife Ranya’s company) which makes almost everything and anything creative jewelry wise has made me something random called Nuns Knickers for my dslr setup and Mattebox. This is basically what it is. A mattebox comes with usually a multitude of foam donuts or circular inserts to help block light coming in from behind the mattebox and above the lens. This donut usually needs to be changed out depending on the diameter of your lens. And because I have a Rokinon 14mm which has a HUGE diameter because there is a non removable lens hood and the glass is just huge to get the wide 14mm angle I can’t use the same donut for let’s say my 55mm. I would have to unscrew the donut holder and place in another donut to fit a smaller lens. This takes too much time in the field while shooting. So I did a little research and found 2 companies that make these universal light blockers. First is Zacuto‘s Universal Donut found here with a video to demonstrate installation. This is just a little too expensive for me so I check out the second alternative with a company called Genus. They have one called Nuns Knickers which I find very funny so I am using this as the name for my homemade one. Here is the Genus one which is definitely a little cheaper than Zacuto’s and differently made as well. I went another route and had my wife make me one with draw strings built in. I had some bose headphone bags and doubled them up to make sure light wouldn’t get through and cut a hold in the bottom of each. Also, cut them way down because I only need about 3 to 4 inches or even less between the mattebox and lens. So far this had been working great. It can be a little difficult to get the draw strings around a smaller lens but so far it works. The pictures below show some of the earlier versions which was slightly too large. The “Knickers” have been cut down to about 2″ now and seem to work better.
