Lens for wedding

[arcamalpha]

I'm taking some photos for a small wedding and need to pick an appropriate lens for the ceremony. It's a fairly small room, perhaps 7m long.

I only want to take one lens in with me as there's no time to swap. I have a choice of 50mm/F1.8, 17-40/F4, 24-85/F3.5-4.5, 70-200/F4.

I'm thinking the 50mm will do nicely given the likely low light levels, however, I wonder if I'll need something longer for close-ups.

Any thoughts or experience?

I'd take the 50mm just in case the lights poor, you can always get a bit closer to the subject if you need to.

50mm, the others work as well.

Are you using the onboard Flash, or a mounted Flash unit?

If you are using a decent Flash then I would take the 17-40 F4 for the greatest range. You said the room was small. That might mean you need a wide lens.
On the other hand, the longer lenses are better for portraits. Just take them all and change once!
