[QUOTE="hark, post: 677927, member: 13196"] Greg, depth of field at 35mm f/2.8 isn't the same as the depth of field at 70mm when set at f/2.8. Telephoto lenses have a shallower depth of field than wide angle lengths when using the same aperture. To summarize, these are the factors that yield bokeh: [LIST] [*]As I just mentioned, the focal length contributes to depth of field especially when using a fast lens. So the longer the lens, the shallower the depth of field. [*]The distance between you and your subject is another factor. The closer you are to your subject, the shallower the depth of field. [*]And distance between your subject and the background can contribute to bokeh. The further your subject is from the background, the better your chances of yielding bokeh. [*]Fast lenses when shot wide open offer more bokeh than when stopped down in the same situation. [/LIST] [/QUOTE]
