I am wondering if anyone has any advice for me. A friend has set-up an opportunity for me to shoot photos for a small awards ceremony. It is in a small venue with unknown lighting and no ability to preview. I am just starting out (and still learning) so i don't have a lot of equipment. I have a Nikkor 50mm 1.8G lens, a Nikkor 24-85 3.5-4.5G lens, Nikkor AF 28-100mm 3.5-5.6G and a Sigma 70-300mm 4-5.6 lens (no image stabilization)...I have only 1 camera body, D600. I am wondering which lens you would use primarily? Also if you have any advice, I would appreciate it. I know that I need to invest in good glass, but I can't afford to before the event (next Thursday) and nor am I in a position to rent anything. Thank you for your feedback......I am open to anything constructive.
