What is the difference between Continuous Advance Priority AE and Hi/Lo Continuous Shooting?

Applicable Products and Categories of This Article

Continuous Advance Priority AE on the Mode Dial allows the camera to shoot at its highest frames per second (fps). In Automatic Auto Focus (AF-A) or Continuous Auto Focus (AF-C), the shutter speed is automatically selected by the camera and the aperture is set to the fully open position of the attached lens. In Single Auto Focus (AF-S) and Manual Focus (MF), aperture can be manually selected, but the camera controls the shutter speed automatically.

Hi/Lo Continuous Shooting in the Drive Mode settings gives you the option of selecting a high or low fps speed, whichever might best suit your purpose. The Hi setting shoots up to 8 fps. The Lo setting shoots up to 3 fps. You can adjust both the aperture and shutter speed manually when the Mode Dial is set to the P/A/S/M modes or automatic settings like the AUTO or AUTO+ options.

In summary, Continuous Advance Priority AE can shoot at a higher fps than Hi/Lo Continuous Shooting, but with slight limits on aperture or shutter speed control since the camera chooses those values automatically for you. On the other hand, while Hi/Lo Continuous Shooting may not use a higher fps than Continuous Advance Priority AE, you have more flexibility for controlling the aperture and shutter speed.
