For others, don't forget to see the whole optics section of the site, it has articles on many aberations and also includes a simply GREAT program for calculating Depth of Field, angle of view, depth of focus, et cetera, even among different film formats. The best DOF calc I have seen so far (the better theoretically gifted than me can assess if the equation the guy uses are correct, as he clearly states all the equations in the docs. I am inclined to believe him though). Best regards, Frantisek Vlcek
