I have an event coming up in a few days time. I'm taking photos of my friend as he will be up on stage. It would take place in a sports hall, with performances & all. I will be shooting mainly people & big group of performers. I would say the area is pretty well-lit (typical sports hall lighting).
I'm using a 50D with kit lens (18-135). Is it advisable to rent an additional lens (I was thinking more of telephoto, for the extra reach) & an external flash? Or am I good with my current set up.
Many thanks in advance!
