Hi everyon, I come to seek suggestions on lens selection. I am invited to a friend's PhD. graduation ceremony. I want to take some photos for him. Question is I have no idea what will happen during the event and how far apart my friend and I would be. Has any of you attended such event? Which lenses should I bring? I have a FF camera. I'll definitely mount a 24-105, then should I bring a 70-200 2.8 or 100-400 for telephoto? I am reluctant to take both. Or you have some other suggestions, please feel free to let me know.
Thanks in advance
