I am new in DSLR and I hope someone can advise.
I recently got my D60 and plan to upgrade with one of the following options
1. Speedlight SB-600
2. Speed lense
To take kids photo in house and some time outdoor, which option should I go first. If speed lense is recommended, which lense should I go for (third party lense is welcomed).
My budget should not exceed $600.
