Shutter Speed Calculator

Here you have a universal shutter-speed calculator that will allow you to calculate action stopping or blur producing shutter speeds for any film or digital camera. You simply have to enter the size in millimeters of the short side of the film or sensor into the 'Short Side' field. Always use the actual focal length of the lens for the calculations. You may also be interested in my Depth-of-Field Calculator and Field-of-View Calculator.
