Hi, i am a really begginer when it comes dslr's but i want to take some photos of a jazz band tommorow. I will be using a Canon 400d. I have the choice of the stock 18-55mm canon lense, a tamron 70-300mm or a tamron 28-80mm.Which should i use and what are some basic settings for shooting in dimly light areas. Thanks anyway. Here is the place.
