yeesh wrong thread all of you

As the format/film you want to cover gets larger, the image circle gets larger, so field of view gets bigger for a given focal length. Longer the focal length, the slimmer the plane of focus will be. So with large formats you can have a lens that has a wide angle of view, but a slim plane of focus with the foreground and background all blown out of focus.
If you have a good frame of reference for 35mm focal length fields of view, imagine what its like looking through a 50mm lens on an old film slr, and picture how big a 35mm negative is. Now imagine your negative was 10x bigger, and you had a 50mm lens that could cover that negative, you would be seeing a much much much wider field of view, but the thin plane of focus would be the same.
edit: jeeze missed a whole page discussing this
double edit: I have and love the original x100, have a small sensor LX-5 which is a great camera to have in a handlebar bag. Hated the couple micro4/3 cameras I had partially because the sensors sucked and mostly because I hate 4x3 ratio.
whatever that bokeh shit is makes me dizzy af
almost as dizzy as all this camera chat
