I've been looking at cameras and understand they can be programed with aperture priotity etc. Some cameras say they have "shiftable" program and others say that the program is not always "shiftable". Anyone know what "shiftable" means?
A better description, Shiftable Program mode, when using this mode the camera selects aperture value and shutter speed for you automatically. However if you want to change either the aperture or the shutter speed there is no need to switch to Aperture Priority or Shutter Priority,
By moving one of your control wheels, the f-stop and shutter speed will be adjust up/down respectivley in one direction and down/up in the other direction. This happens in either half-stop or 1/3rd-stop increments depending on your camera.
Believe me, this feature can avoid wasting an unexpected opportunity, because you can control either value in an instant.
