Hi, I am looking for some advice from more experienced photographers than me: I was recently asked to take some pictures during a short animation festival organized by a friend of mine in October for their website and other promotional material. The shots schould give an impression of this festival and its visitors, et cetera. I am a novice photographer and my current gear is a Canon 450d with a Sigma 50mm f1.4 and a Canon 17-40mm f4 (I also have a yongnuo 560-II manual flash). My friend is not expecting high professional quality work, it's unpaid and is just a favor and he wanted me to help. I am not that worried about the shots themselves, but I am completely not used to the situation: shooting before, during and after the showing of the short animations means no flash, but (obviously) the whole situation will be pretty dark (it will be in a movie theater or a big room build to look like one). I will also not use a tripod. And that is my problem: what kind of gear do you use or would you advice to use for such a situation. My Sigma is f1.4 is pretty good, but it is also 50mm on a crop-sensor so it is very tight (equivalent of 80mm). The 17-40 is the right length I think, but f4 does not really work that well in low light conditions. Also, because my Canon 450d can't really do high ISO; 800 is allready pretty bad. I am absolutely willing to rent gear, I just don't know what to rent exactly. I was thinking of a Canon 5d mark II or III with a 24-70mm f2.8. Is that good enough to shoot in low light without flash? I am also interested in your stories on such a project. What worked for you and what should I try to avoid. Thanks for all your help!
