if you have the opportunity to go into a store, put the various wide-angle lenses on your camera and see which has the field of view you would like to work with, which handles the way you want it. Different people have different choices. These days, my choice is not to go with a prime at all and use the Panasonic 8-18. On my Pen-F. Together with the 14-150II. To just walk around with.
