i am thinking of getting this lens to compleat my wide angle area, does anyone have any input on this idea.
i currently have
tamron 19-35
tamron 28-75
canon 50mm 1.8
canon 100-400 l is
20d, eos3, 430ex flash
and a manfroto tripod and ball head
i intend to switch my tamron 19-35 for a canon 16-35l 2.8, and the 70-200l 2.8 but for now i am thinking of getting the sigma 10-20, any ideas on this thanks for you input.
