I just picked up a (barely) used copy of the subject lens. I like it so far, but my copy didn't come with a lens hood, and I've quickly discovered the hood is definitely needed. My question: Since the Tokina hood is relatively hard to find (my excellent local shop that normally has everything doesn't stock them) I'm hoping someone knows of another option, i.e., maybe a more easily sourced Nikon hood would fit? If so, which model? I can order the Tokina hood from B&H but am in a bit of a hurry and would like to find something more quickly if possible. Any ideas?
