Will be shooting a fren's weddding next month and am in a bit of a dilema. I have a D7100 and the following lens: Sigma 17-50/2.8, Nikon 16-85 VR2, Nikon 18-105 VR and Nikon 55-200 VR. I only want to bring at most 2 of these 4 lens (if possible just one as i still have to bring a 35mm prime). Which 2 should i bring?
1. Sigma 17-50 - my only constant f2.8 lens should be useful in generally dark ballroom
2. Nikon 16-85 - widest lens i have for taking those table group photo (although ultimately only 1 mm wider than sigma so may not be a big deal) and also significantly more reach than the sigma
3. Nikon 18-105 - not as wide as sigma or 16-85 but has longest reach of the 3 but prob the lowest IQ
4. Nikon 55-200 - longest reach
If confirm that i don't need more than 100mm (150mm FF equiv) focal length then i can immediately rule out the 55-200. The other 3 is less simple. As i have not shot wedding before i am not sure if just the Sigma 17-50 (24ish - 75ish FF equiv) alone is enough to cover the whole event. If it is then this will be my choice due to the f2.8. On the other hand if 50mm if not long enough then i will need to bring either the 16-85 or 18-105. Needless to say i rather bring the 16-85. But if i need even more reach than 85mm (120++ FF equiv) then i will need to bring the 18-105. From the test shots i have taken, i can't say for sure that the 16-85 has better IQ than 18-105 but psychologically i rather not shoot with a kit lens.
I did consider getting a d600 and 24-120 f4 and solve all the problem but the $$$ hurts.
