Max aperture all the way, all the time folks are interesting breed... Its really odd to see their group photos of people, where only one or two are in focus and the rest out of focus because they are on a different focus plane just a foot behind or in front of the others that are in focus, or the use of crazy shutter speeds like 1/4000 of a second outdoors in every shot so they can use that aperture. I wish they would realize that they dont need to spend all that dough and just use a lens of a longer focal length to get some of that bokeh they want.
