Q: 6. 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: 10. I have the Rokinon 14mm. does the Lee filters work great with this lens?, Does it vignetting too much?
