Q: 1. What do I need other than a wide angle adapter to be able to use 77mm CPL with this, does the tandem adapter need extra adapter to mount on the holder?

A: If you have one LEE Filter Foundation Kit, you'll need a second one to hold the tandem adaptor. If not, you'll save a few bucks by buying the complete kit (with two tandem adaptors).

Q: 2. I have a rokinon 14mm, nikon 24-120mm and nikon 70-200mm. Is it work for all of them?

A: This will only work with the Samyang/Rokinon 14mm f/2.8 ED AS IF UMC Lens. It will not work with the Nikon lenses listed as well.

Q: 3. will this adapter ring work willthe canon 14mm f/2.8L version 1 lens ?

A: This equipment is lens specific. Lee designed the system for specific ultra wide angle lenses only.

Q: 4. Can I use this on a Nikon 10-20mm f/4.5-5.6G VR?

A: Yes you can. It just requires an adapter ring which would be 72mm for the lens in question. Lee is a great system. You'll love it.

Q: 5. This holder fits tokina 11-16 mm lens (for Nikon d7100). Generate vignetting?

A: This is an adapter ring only for the Tokina 16-28mm f/2.8 lens.

Q: 7. Does the pouch work well with the glass filters like the big stopper & polarizers?

A: Yes, it works with 150x150 filter perfectly.

Q: 8. The lens cap no longer fits once the adapter is fitted. Neither the adapter or filter holder comes with a lens cap and I cannot find one. What is used to protect the lens with the adapter in place?

A: I cannot speak directly to the Canon lens, as I use a Nikon 14-24. If they're similar, I can tell you that on the Nikon, Lee provided a neoprene sock for lack of a better word. It fits snugly, and actually does a better job of keeping dust off the lens glass. Also, the lens cap provided by Nikon does still fit, barely. However, I added a piece of gaffers tape to the rim of the lens cap, making it fit more snugly, and that holds the original lens cap nicely. So for me, I have two ways that work. Ultimately, I use both simultaneously. The neoprene sock certainly will not protect the lens glass from ANY kind of impact. I've seen some videos where people are frustrated that they have to choose one or the other. Nonsense! I simply places the hard lens cap inside the neoprene sock and place over my lens. Best of both worlds. In fact, I ordered an extra sock for my other 14-24, as added dust protection. They work great! Hopefully, your Canon will have similar success!

Q: 9. I have rokinon 14mm, nikon 24-120mm and nikon 70-200mm, i want to buy just one holder and wonder does it work for all of them

A: This adapter ring will not work with all of those lenses. You will need to purchase a corresponding adapter ring for every lens that would also fit the SW150 II holder.

Q: 10. Has the basic filter holder been redesigned recently? I have an old version that is all plastic with threaded inserts for the screws. I recently saw a Lee lens hood that had a center ring that was metal that was fused to the plastic. Is the current 2014 holder plastic -metal hybrid or all plastic?

A: This filter holder is made of a heavy duty, high impact plastic with metal screw threads built in.
