i'll be going to the jurong bird park this weekend..
would like to know which of these 2 lenses is a better choice on a 1.3x cropper..
canon 70-200 f4L or tamron 200-400 f5.6?
is 200mm long enough or will the birds be quite far away?
cos i'm more concerned about the tamron's slower AF, softness n weight compared to the canon..
what aperture size to use? and any other valuable tips/pointers?
