So you have a Sigma 8-16mm (or any other similar lens that won't take filters, like the Samyang 14mm). You want to use filters. You've thought about buying some of those massive Lee filters and then rigging it somehow. Their Nikon 14-24mm filter mount kit tempted you until you saw the ridiculous price. You thought about buying some of the filters on their own, but it just didn't feel right... Yet when you go out with your lens, you have that nagging feeling, that ex-wife glare, staring at you from somewhere deep inside your head?
Don't despair! I bring hope!
1. Go to the Fotodiox page. Look for the 14-24mm Filter kit. Don't worry, you don't actually need the adapter. Buy the filter you want (I grabbed the ND8).
2. Go to Walmart. Buy some craft foam board. One big sheet is way more than you'll need. Buy some double sided sticky tape. Buy a roll of black electrical tape. Buy a Velcro kit, the kind that has a sticky back.
3. Cut squares in the craft foam board that are the right size for the filter to sit on, where the edge of the filter will just reach the edges of the square. Cut a hole in the pieces of foam board, making it the right size to slide over your lens. Make the hole a little larger than needed. If you are using the Elmer's Craft Foam Board you'll want to stack four squares to make your adapter the right thickness.
4. Now you should have 4 (or whatever) squares of foam board, all the same size, with holes in the middle in the same spot. Don't worry if the edges look awful, it doesn't matter. Stack them on top of each other with the double sided sticky tape.
5. Wrap the entire thing with black electrical tape. Stick on a piece of partially folded over velcro in two (or four, if you wish) places on the edges of the new "filter holder" you created. Apply electrical tape over the Velcro to make it even more secure.
6. Stick two (or four, if you wish) thin strips of velcro to the edges of the filter itself.
No vignetting at 8mm, yay:
