Do You Know the Reciprocal Rule of Shutter Speeds?

There is a great way to get more stable images without worrying about image stabilization from your lens or camera: it’s called the reciprocal rule of shutter speeds. SLR Lounge recently published a video all about it, which is after the jump.

The reciprocal rule of shutter speeds states that:

  • In order to achieve a stable image that is devoid of camera shake, you must shoot at a shutter speed that is the reciprocal of the minimum of the field of view.
  • What does that mean? If you’re using a 100mm lens on a full frame 35mm sensor/film body, then you need to shoot at at least 1/100th to produce an image that contains no camera shake when shooting handheld.
  • If you’re shooting with a 100mm lens on an APS-C sensor that has a 1.5x crop factor, then you need to shoot at 1/150th at a minimum. Here, the crop factor is taking into consideration.
  • If you’re shooting with a 100mm lens on an APS-C sensor that has a 1.6x crop factor, then you need to shoot at 1/160th at a minimum. Here the crop factor is also taken into consideration.
  • Micro Four Thirds shooters need to shoot with a 100mm lens at a minimum of 1/200th because of the crop factor.

The SLR Lounge video below visually demonstrates this idea.
