Here is the specs of my lens, and cam is 350D. I need to calculate the
diagonal distance of the smallest box (W/L = 3/2) which can exactly fit
into the frame. Is this formula correct?
D = 2 * (220cm * tan(6.2/2)) / 1.6 = 14.89cm.
Angle of View 18.2 - 6.2 degrees
Minimum Focusing Distance 200- 220cm
Maximum Magnification 1:5.3
