I was asked a question by a budding sports shooter today and I was stuck for an answer. He is wanting advice on something for basketball, baseline under the basket. 24-35mm range. And he does not have $1500.00 for the Canon 35 f1.4L. (What I use). For those sports shooters, which would be your choice, or is there something not mentioned in the $600 or less range. These were my thoughts. Canon 28mm f1.8. http://www.bhphotovideo.com/c/product/102851-USA/Canon_2510A003_Wide_Angle_EF_28mm.html Sigma 24mm f1.8 http://www.bhphotovideo.com/c/product/217772-USA/Sigma_432101_W_A_24mm_f_1_8_EX.html Sigma 28mm f1.8 http://www.bhphotovideo.com/c/product/217758-USA/Sigma_440101_W_A_28mm_f_1_8_EX.html Sigma 30mm f1.4 http://www.bhphotovideo.com/c/product/381615-REG/Sigma_300101_30mm_f_1_4_EX_DC.html Canon 35mm f2.0 http://www.bhphotovideo.com/c/product/12119-USA/Canon_2507A002_Wide_Angle_EF_35mm.html I've not shot any of them. The two top requirements are sharpness wide open and fast focus speed. He is using a crop body and has no plans to change from a 1.6 crop. Looking forward to the suggestions. He is looking now so he can save and be prepared for high school b-ball this winter.
