I wanted to use this lens for indoor photography without a flash. I have 50mm f1.4 and 35mm f2.4 but sometimes they are too long, especially for group shots. I want a Sigma 18-35mm f1.8 but can't afford it. Some of the reviews on this lens have been negative, but I think it's perfect for my purposes. My pictures turn out much better than pictures taken with flash cameras. This lens is big and heavy, especially compared to my tiny, light 35mm f2.4 lens, but I like the weight because it's easierโฆ
