so i herd u liek filterz (or, how to use filters on the Sigma 8-16mm)

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.

7. Enjoy!

whoah that is WIDE!!

I bet your camera was just about touching that cat condo

>inb4 rules 1 and 2

That is huge!

lol. What's funny is that I did not buy the 8-16 because I could not find a suitable way to use filters and I had looked at all the options you had mentioned.

Haha I know, there is truth in it.

amy chance you might do a step by step with pictures? I'm considering this lens and thing your idea is good I'm just not great at DIY when left to my own devices haha.

also is that the 145mm ND filter?

One idea

Also check Lee Filter SW150, it's a bit rich and for Nikon 14-24 but the plans were to make adapters for other lenses.

Yep, that's the 145mm filters. I doubt I'd do a step by step with pics, but if i ever build another one I will. :P

I've seen those links before, as well, they are great links. The issue w/the 8-16mm is the integrated hood is more "annoying" than the integrated hood on the 14-24 (play with one and you'll see what I mean). In order to get it to not vignette you must press the filter so it's basically touching the hood. Even the 145mm filter will vignette if you move it out even a little bit away from the hood, it must be almost in contact. I wanted something specifically for the 145mm filter from fotodoix, because they are large, glass (good quality and won't scratch), but also very inexpensive.

To make a "nicer" version of what I did, you could do this:
1. Order the part that the lens cap sits on for the 8-16mm (the round part that slides onto the lens).
2. Cut it down to size (making it shorter)
3. Use epoxy and some fiberglass tape (or metal if you have the tools to cut that stuff) to attach a Lee (or w/e) filter holder to that.

My main goal was to have something that worked well, could use that inexpensive glass ND filter, and would be under $10 to make. lol
