Q: 5. I'm thinking of getting this lens for my Canon 50mm f1.8 with Canon 6D and T3i. Does it cause vignetting or reduce the light value?

A: Adding optics to a lens is at the most going to do no harm but in general it is not going to improve the lens optics. And with a wide angle add-on-lens it will distort. It is always better to use a lens not an add-on-lens.

Q: 8. I own the new Nikon P900 camera. I want a filter to protect the lens. Which filter works better to protect the lens, a clear glass filter or a UV filter?

A: In the days when Film was the only medium, the UV filter was definitely the way to go. With digital, most seem to prefer the clear glass filter. I own both (a hold-over from the days of film) and for the most part, I use the Nikon Clear Glass Filter on all my lens on my Digital SLRs. I'm still using UV on my Nikon F-100 for the shorter lenses, Skylight for longer ones. Hope this helps.
