'Sup, guys. Just wanna offer some questions to throw around here.
To start off, I'm on the Canon 450D. My plan is to rent a 17-55mm f/2.8 IS USM and a Speedlite 580EX II for the upcoming Cosfest 2009. Previously, there had been some photos taken last Saturday at Suntec (Games 'Xpo 2009). I've taken a look at some of these pictures, and the common thing I see from them is the use of a flash unit to fill in the lights in an otherwise dark environs.
Reading around the forums here, I noticed that the common refraint was to use prime lenses if I forgo the flash unit: the large apertures these lenses allow more light to enter.
My primary purpose for the event is to "record down the events as it happens." My secondary purpose is to "take the lovely portraits of each cosplayer in their full splendour."
So, a 450D (sad to say, gentlemen, I want to stick with my DSLR now), a 17-55mm f/2.8 lens (will be saving up for this baby before November), and a 580EX II. Is it a wise decision, or do you have any other comments that you can bring up?
