Well, it's my first and I have no idea how to use it. I keep looking for the zoom ring and I simply am lost as to what will work. Here are a couple of images I took this morning. Obviously just test shots. But I intend to not only use it as is, but to also put the panotools to work and see what I get out of that.
So, what special considerations should I be taking in to take into account the special needs of this lens in as far as lighting and composition goes?
