Good lens for weddings?

[PegLeg Media]

I have all my panasonic lenses under 50mm and love them, but now i need a good lens for when I film weddings/live bands. I was thinking about getting one of the stock 14-140 or 45-150mm lenses but dont know how they would do in low light, since most weddings are indoor with low lighting. I would also like something parfocul so I can zoom in for closeups at certain parts but I could live without this. So what do you guys use for weddings?

I use the 35-100mm for wedding service and speeches. never know how far/close you can be to the action.

I'm using a Sigma 24-70 F2.8 nikon mount, manual aperture with a metabones speed booster, which translate to 17-50 F2 approx. I use faster primes when I have the flexibility otherwise the sigma provides decent focal coverage and nice speed for a zoom.
