Okay I bought the 50mm f/1.8 lens and love it. What would be a good lens (price/performance), for shooting groups(like 6 to 16 people) in the sunlight and in low light. BTW this is with the Rebel XT...
From the picture he posted in another thread I assumed he already has the kit lens. Another suggestion would be the 17-40 f/4 L, which isn't exactly cheap either.
