Be Prepared

So I ordered a Zeiss 85mm f/1.4 from Borrow Lenses, but later found out that I forgotten some information for my address and ended up needing to get a full refund. And this was for a gig tonight since I know that the lighting was going to be terrible for my lens since it can't handle low lighting. But I have lights that I'm bringing with me to the banquet so, what I'm saying is that because I know how to use the lights that I have I can use them to my advantage to help my lens see better and increase my aperture to around f/16-22 to make sure that the photo is as sharp as it can be.
