What are the absolute best budget lenses for L-mount video work right now because I am in a serious bind? I just picked up a Lumix S5II and totally blew my budget on the body and some extra batteries and now I realized I have a wedding gig next Saturday and my kit lens just isnt gonna cut it for those low light reception shots. I need something fast but I literally only have about 550 bucks left in my bank account for this.

I am looking at three main options right now. The first is the Panasonic 50mm f1.8 because I heard the autofocus is native and super smooth for video but Im worried it might be too tight for some of the indoor shots. Then there is the Sigma 28-70mm f2.8 Contemporary which would be way more versatile but even used it might be pushing my 600 limit and I dont know if the f2.8 is enough for a dark ballroom. I also saw that super cheap TTArtisan 50mm f2 and Im tempted just to save the money but Ive never used manual glass for a high pressure event like this and Im scared Ill miss focus every single time.

Since Im in Chicago I can probably run to a local shop but I need to decide tonight so I can order it if they dont have it in stock. Should I just play it safe with the Panasonic prime or try to find a deal on that Sigma zoom so I dont have to keep swapping lenses mid-ceremony?
