No wedding expert here - have only shot one wedding! On that one occasion, the Tamron 28-75 was the most useful. Two others that were used quite a bit were the FA 100 macro, and the A 70-210 F4 - both quite sharp even wide open, and both good color rendition of skin tones, etc. The DA 12-24 was useful for some interior church shots, and for some large group shots. Had brought along the A 50 F1.4, but never used it...
