Shifting from Autofocus to Manual Focus on Your Canon EOS Rebel T3/1100D

Your Canon EOS Rebel T3/1100D offers an excellent autofocusing system. However, with some subjects (such as low-contrast scenes, like foggy mornings), autofocusing can be slow or impossible, which is why your camera also offers manual focusing.

Make the shift from auto to manual focus as follows:

  1. Set the AF/MF switch on the side of the lens to the MF position.

    This switch sets the focus operation to either auto (AF) or manual (MF). The following figure shows you the switch as it appears on the Canon Rebel 1100D kit lens. The switch should be in a similar location on other Canon lenses. If you use a lens from another manufacturer, check the lens instruction manual.

  2. Look through the viewfinder and twist the focusing ring until your subject comes into focus.

    On the kit lens, the focusing ring is at the far end of the lens barrel, as indicated in the figure. If you use another lens, the focusing ring may be located elsewhere, so check your lens manual.

    If you have trouble focusing, you may be too close to your subject; every lens has a minimum focusing distance. (For the kit lens, the minimum close-focus range is about 10 inches; for other lenses, check the specifications in the lens manual.) You also may need to adjust the viewfinder to accommodate your eyesight.

Some lenses enable you to use autofocusing to set the initial focusing point and then fine-tune focus manually. Check your lens manual for information on how to use this option, if available. (This option isn't offered on the kit lens.)
