General Precautions Shooting Precautions The aperture setting is fixed at f/11 on this lens, and cannot be adjusted. Adjust exposure using the shutter speed and ISO speed. zz Be aware of the following when selecting a shooting mode. • If [P] mode is selected, shutter speed is adjusted while the aperture setting remains fixed at f/11, and so actually it is the same as if selecting [Av] mode. • If [Av] mode is selected, the aperture setting cannot be adjusted. • If [Tv] mode is selected, the aperture setting is not adjusted, and so actually it is the same as if selecting [M] mode. • If [Fv] mode is selected, it is actually the same as if selecting [Av] or [M] mode, depending on the shutter speed and ISO speed settings. zz Also be aware of the following when shooting. • Since the aperture setting cannot be changed, the effect gained from stopping down (depth of field) cannot be adjusted. • When using safety shift and the camera automatically changes the manual settings to allow shooting at standard exposure, the aperture setting is not adjusted. • During AEB (auto exposure bracketing), the aperture setting is fixed at f/11 and does not change. • When using Portrait mode in the Special Scene Modes (on EOS RP cameras), the depth of field cannot be adjusted for a shallower depth, since the aperture setting cannot be adjusted.
