I have shot a few weddings as second photographer with my 50D, 15-85, 70-200 2.8 II, 50 1.8 and 580EXII. I have started to go on my own this year and have added a 5D3 and 24-105 to my gear. Now I'm in a dilemma as to how to optimize my lenses. Obviously 15-85 on crop and 24-105 on FF are redundant. Should I replace the 15-85 with either a prime (maybe 35L?) or 24-70?
Complicating this further is that on some occasions my wife will be using the 50D to shoot groom and his party while I'm somewhere else shooting bride's preparations. I guess she could use 24-105 then and I will stick with the 35L or 24-70, whichever I get, for the bride's prep shots.
Any advice would be appreciated.
