Thanks for the suggestions

I do have a Sigma 70-200mm f/2.8 but it's heavy and I don't want to be lugging it around all day!

Ideally I just want one lens. I wont be doing the group shots (because I will have to been in them) so it will just be for the candid type bride getting ready and reception shots

I have been roped into taking some pictures at my brothers wedding as they are on a tight budget.
They do have a pro booked for few hrs to cover the church and a little while after, but I have said I will attempt the bride getting ready and reception (and the next day's picnic) photos.

I am going to hire from http://www.srsmicrosystems.co.uk/hire/ and was thinking about the Pentax DA* 16-50mm F2.8 SDM Lens will this be suitable? (To use with a K-5 IIs)

Thankyou

Sorry guys!
