Yes, Yes, Yes---For my the Wedding Job
1) Canon 24-70 f/2.8 II
2) Canon 85 f/1.2 II
As you say, BUT, I add 3 more lenses for some situation in most of wedding :
3) Canon TS-E2mm, F/ 3.5 L MK II = for 4-5 shots At Shift Function, for the Big group( 100 People) Photos, and combine them as panorama - 1 photo = Super Larged File for Super Larged $ 1000 US Dollar Print---Ha, Ha, Ha.
4) Canon 70-200 mm. F/ 2.4 L + 1.4X or 2X for shoot at the Balcony 1,000 Feet away from Altar--Where the PRIEST not let the Photographer around his Territory, Because your Machine gun sound, might make him forget his pray--------If The Balcony is shorter distant from Altar ( in small church/ Sanctuary), EF 135 F/ 2.0 L. is extra Nice for the Dark/ Candle light At Ceremony area.
5) If you go to take the photos for the Wedding of Prince and Princess----Ha, Ha, Ha, You must have 600 mm OR 800 mm. Lens with 2X too----They not let the Photographers with in half of Mile.
IF you can GO ANY PLACE AND ANY TIME DURING THE WEDDING, JUST ONE LENS IS ENOUGH FOR ME = EF 50mm, f/1.2L USM ---Just use your strong legs as ZOOM function---Can use from dark indoor party to the bright sun shine place.
Have FUN for your job.
PS. AS the Wedding PRO, They use 3 People to carry the 3 Support Lights for best 3D Liked Photos---One at the 45 degree Left or right of the Subjects for side light, One at the Back of the subjects, for Back Light, and the most one from 45 degree Back of the subjects at High elevation for the Hair light-----Yes, I forget another helper, The Last one to carry the Cooler full with the Beers that you like.
